Aldehyde dehydrogenase 2 (ALDH2) enzyme oxidizes alcohol-metabolized carcinogenic acetaldehyde into acetate. It is well known that the inactive ALDH2 carriers, specific to East Asian populations, have an increased risk of several cancer types because of increased exposure to acetaldehyde after alcohol consumption. The aim of this study was to examine the association between alcohol drinking and bladder cancer risk using data from ten population-based prospective cohort studies in Japan, where approximately 40\% of the population has inactive ALDH2 enzyme. METHODS: We analyzed 340,497 Japanese participants with average follow-up of 13.4 years. The association between alcohol drinking and bladder cancer risk was evaluated using Cox regression models within each study, and random-effects models were used to estimate pooled hazard ratios (HRs) with corresponding 95\% confidence intervals (CIs). RESULTS: During 4,729,071 person-years, 936 men and 325 women were newly diagnosed with bladder cancer. Our results showed no evidence of significant association between alcohol drinking and bladder cancer risk even among men who consumed alcohol of ≥69 g/week, with HR of 1.02 (95\% CI, 0.79-1.33). The null result was observed consistently among women. CONCLUSIONS: Our findings do not support an association between alcohol drinking and bladder cancer risk in the Japanese, at least without consideration of the polymorphisms of alcohol-metabolizing enzymes.}, language = {eng}, number = {7}, journal = {Journal of Epidemiology}, author = {Masaoka, Hiroyuki and Matsuo, Keitaro and Oze, Isao and Ito, Hidemi and Naito, Mariko and Wada, Keiko and Nagata, Chisato and Nakayama, Tomio and Kitamura, Yuri and Sadakane, Atsuko and Tamakoshi, Akiko and Tsuji, Ichiro and Sugawara, Yumi and Sawada, Norie and Mizoue, Tetsuya and Inoue, Manami and Tanaka, Keitaro and Tsugane, Shoichiro and Shimazu, Taichi}, month = jul, year = {2020}, pmid = {31204364}, pmcid = {PMC7280052}, keywords = {Adult, Alcohol Dehydrogenase, Alcohol Drinking, Aldehyde Dehydrogenase, Aldehyde Dehydrogenase, Mitochondrial, Asian Continental Ancestry Group, Female, Humans, Japan, Male, Middle Aged, Polymerase Chain Reaction, Polymorphism, Genetic, Prospective Studies, Urinary Bladder Neoplasms, alcohol drinking, bladder cancer, cohort study, pooled analysis}, pages = {309--313}, }

We sought to establish globally scalable technology, policy, and procedures for sharing biosamples and associated genomic and phenotypic data on broadly consented cohorts, across sites of care. METHODS: Three of the nation's leading children's hospitals launched the Genomic Research and Innovation Network (GRIN), with federated information technology infrastructure, harmonized biobanking protocols, and material transfer agreements. Pilot studies in epilepsy and short stature were completed to design and test the collaboration model. RESULTS: Harmonized, broadly consented institutional review board (IRB) protocols were approved and used for biobank enrollment, creating ever-expanding, compatible biobanks. An open source federated query infrastructure was established over genotype-phenotype databases at the three hospitals. Investigators securely access the GRIN platform for prep to research queries, receiving aggregate counts of patients with particular phenotypes or genotypes in each biobank. With proper approvals, de-identified data is exported to a shared analytic workspace. Investigators at all sites enthusiastically collaborated on the pilot studies, resulting in multiple publications.

Tryptophan depletion in pregnancy is facilitated by increased activity of tryptophan-depleting enzymes [i.e. the indolamine-2,3 dioxygenase (IDO)1 and IDO2) in the placenta. In mice, inhibition of IDO1 activity during pregnancy results in fetal loss; however, despite its important role, regulation of Ido1 gene transcription is unknown. The current study shows that the Ido1 and Ido2 genes are imprinted and maternally expressed in mouse placentas. DNA methylation analysis demonstrates that nine CpG sites at the Ido1 promoter constitute a differentially methylated region that is highly methylated in sperm but unmethylated in oocytes. Bisulfite cloning sequencing analysis shows that the paternal allele is hypermethylated while the maternal allele shows low levels of methylation in E9.5 placenta. Further study in E9.5 placentas from the CBA/J X DBA/2 spontaneous abortion mouse model reveals that aberrant methylation of Ido1 is linked to pregnancy loss. DNA methylation analysis in humans shows that IDO1 is hypermethylated in human sperm but partially methylated in placentas, suggesting similar methylation patterns to mouse. Importantly, analysis in euploid placentas from first trimester pregnancy loss reveals that IDO1 methylation significantly differs between the two placenta cohorts, with most CpG sites showing increased percent of methylation in miscarriage placentas. Our study suggests that DNA methylation is linked to regulation of Ido1/IDO1 expression and altered Ido1/IDO1 DNA methylation can adversely influence pregnancy outcomes.}, language = {eng}, number = {4}, journal = {Human Molecular Genetics}, author = {Spinelli, Philip and Latchney, Sarah E. and Reed, Jasmine M. and Fields, Ashley and Baier, Brian S. and Lu, Xiang and McCall, Matthew N. and Murphy, Shawn P. and Mak, Winifred and Susiarjo, Martha}, year = {2019}, pmid = {30403776}, pmcid = {PMC6360327}, keywords = {Abortion, Spontaneous, Animals, CpG Islands, DNA Methylation, Epigenesis, Genetic, Female, Genomic Imprinting, Humans, Indoleamine-Pyrrole 2,3,-Dioxygenase, Male, Oocytes, Placenta, Pregnancy, Spermatozoa}, pages = {662--674}, }

Environmental factors and chronic inflammation are correlated with the disease risk. Diagnosis is performed by transurethral resection of the bladder, and patients with muscle invasive disease preferably proceed to radical cystectomy, with or without neoadjuvant chemotherapy. The anti-tumour immune responses, known to be initiated in the tumour and draining lymph nodes, may play a major role in future treatment strategies. Thus, increasing the knowledge of tumour-associated immunological processes is important. Activated CD4(+) T cells differentiate into four main separate lineages: Th1, Th2, Th17 and Treg, and they are recognized by their effector molecules IFN-γ, IL-13, IL-17A, and the transcription factor Foxp3, respectively. We have previously demonstrated signature CpG sites predictive for lineage commitment of these four major CD4(+) T cell lineages. Here, we investigate the lineage commitment specifically in tumour, lymph nodes and blood and relate them to the disease stage and response to neoadjuvant chemotherapy. RESULTS: Blood, tumour and regional lymph nodes were obtained from patients at time of transurethral resection of the bladder and at radical cystectomy. Tumour-infiltrating CD4(+) lymphocytes were significantly hypomethylated in all four investigated lineage loci compared to CD4(+) lymphocytes in lymph nodes and blood (lymph nodes vs tumour-infiltrating lymphocytes: IFNG -4229 bp p {\textless} 0.0001, IL13 -11 bp p {\textless} 0.05, IL17A -122 bp p {\textless} 0.01 and FOXP3 -77 bp p {\textgreater} 0.05). Examination of individual lymph nodes displayed different methylation signatures, suggesting possible correlation with future survival. More advanced post-cystectomy tumour stages correlated significantly with increased methylation at the IFNG -4229 bp locus. Patients with complete response to neoadjuvant chemotherapy displayed significant hypomethylation in CD4(+) T cells for all four investigated loci, most prominently in IFNG p {\textless} 0.0001. Neoadjuvant chemotherapy seemed to result in a relocation of Th1-committed CD4(+) T cells from blood, presumably to the tumour, indicated by shifts in the methylation patterns, whereas no such shifts were seen for lineages corresponding to IL13, IL17A and FOXP3. CONCLUSION: Increased lineage commitment in CD4(+) T cells, as determined by demethylation in predictive CpG sites, is associated with lower post-cystectomy tumour stage, complete response to neoadjuvant chemotherapy and overall better outcome, suggesting epigenetic profiling of CD4(+) T cell lineages as a useful readout for clinical staging.}, language = {eng}, number = {1}, journal = {Clinical epigenetics}, author = {Ahlén Bergman, Emma and Hartana, Ciputra Adijaya and Johansson, Markus and Linton, Ludvig B and Berglund, Sofia and Hyllienmark, Martin and Lundgren, Christian and Holmström, Benny and Palmqvist, Karin and Hansson, Johan and Alamdari, Farhood and Huge, Ylva and Aljabery, Firas and Riklund, Katrine and Winerdal, Malin E and Krantz, David and Zirakzadeh, A Ali and Marits, Per and Sjöholm, Louise K and Sherif, Amir and Winqvist, Ola}, month = aug, year = {2018}, keywords = {*CD4-positive T lymphocytes, *DNA Methylation, *DNA methylation, *Urinary bladder neoplasms, Aged, Aged, 80 and over, CD4-Positive T-Lymphocytes/*cytology/immunology, Cell Differentiation, Cell Lineage, Cells, Cultured, CpG Islands, Cystectomy, Drug Therapy, Epigenesis, Genetic, Female, Forkhead Transcription Factors/genetics, Humans, Interferon-gamma/genetics, Interleukin-13/genetics, Interleukin-17/genetics, Male, Middle Aged, Neoadjuvant Therapy, Neoplasm Staging, Prognosis, Sequence Analysis, DNA/*methods, Treatment Outcome, Urinary Bladder Neoplasms/genetics/immunology/*pathology/*surgery}, pages = {102--102} }

Ascorbic acid (AA) depletion in malignant tissue may contribute to aberrant normoxic activity of HIF-1α. While AA supplementation has been shown to attenuate HIF-1α function in malignant melanoma, the use of dehydroascorbic acid (DHA) as a therapeutic means to increase intracellular AA and modulate HIF-1α function is yet to be evaluated. Here we compared the ability of AA and DHA to increase intracellular vitamin C content and decrease the malignant potential of human melanoma by reducing the activity of HIF-1α. METHODS: HIF-1α protein accumulation was evaluated by western blot and transcriptional activity was evaluated by reporter gene assay using a HIF-1 HRE-luciferase plasmid. Protein expressions and subcellular localizations of vitamin C transporters were evaluated by western blot and confocal imaging. Intracellular vitamin C content following AA, ascorbate 2-phosphate (A2P), or DHA supplementation was determined using a vitamin C assay. Malignant potential was accessed using a 3D spheroid Matrigel invasion assay. Data was analyzed by One or Two-way ANOVA with Tukey's multiple comparisons test as appropriate with p{\textless}0.05 considered significant. RESULTS: Melanoma cells expressed both sodium dependent vitamin C (SVCT) and glucose (GLUT) transporters for AA and DHA transport respectively, however advanced melanomas responded favorably to AA, but not DHA. Physiological glucose conditions significantly impaired intracellular vitamin C accumulation following DHA treatment. Consequently, A2P and AA, but not DHA treated cells demonstrated lower HIF-1α protein expression and activity, and reduced malignant potential. The ability of AA to regulate HIF-1α was dependent on SVCT2 function and SVCT2 was not significantly inhibited at pH representative of the tumor microenvironment. CONCLUSIONS: The use of ascorbic acid as an adjuvant cancer therapy remains under investigated. While AA and A2P were capable of modulating HIF-1α protein accumulation/activity, DHA supplementation resulted in minimal intracellular vitamin C activity with decreased ability to inhibit HIF-1α activity and malignant potential in advanced melanoma. Restoring AA dependent regulation of HIF-1α in malignant cells may prove beneficial in reducing chemotherapy resistance and improving treatment outcomes.}, language = {eng}, journal = {Biomedicine \& Pharmacotherapy = Biomedecine \& Pharmacotherapie}, author = {Fischer, Adam P. and Miles, Sarah L.}, month = feb, year = {2017}, pmid = {28012930}, keywords = {Ascorbic Acid, Ascorbic acid, Biological Transport, Cell Line, Cell Line, Tumor, Dehydroascorbic Acid, Dehydroascorbic acid, Glucose, Humans, Hypoxia inducible factor-1 alpha, Hypoxia-Inducible Factor 1, alpha Subunit, Melanoma, SVCT2, Sodium, Transcription, Genetic, Tumor Microenvironment}, pages = {502--513}, }

Recently, Fontaine et al. (Science, 347, 2015, 1258524) conducted a phylogenomic analysis of six members of the Anopheles gambiae species complex. Their analysis revealed a reticulate evolutionary history and pointed to extensive introgression on all four autosomal arms. The study further highlighted the complex evolutionary signals that the co-occurrence of incomplete lineage sorting (ILS) and introgression can give rise to in phylogenomic analyses. While tree-based methodologies were used in the study, phylogenetic networks provide a more natural model to capture reticulate evolutionary histories. In this work, we reanalyse the Anopheles data using a recently devised framework that combines the multispecies coalescent with phylogenetic networks. This framework allows us to capture ILS and introgression simultaneously, and forms the basis for statistical methods for inferring reticulate evolutionary histories. The new analysis reveals a phylogenetic network with multiple hybridization events, some of which differ from those reported in the original study. To elucidate the extent and patterns of introgression across the genome, we devise a new method that quantifies the use of reticulation branches in the phylogenetic network by each genomic region. Applying the method to the mosquito data set reveals the evolutionary history of all the chromosomes. This study highlights the utility of 'network thinking' and the new insights it can uncover, in particular in phylogenomic analyses of large data sets with extensive gene tree incongruence.}, bibtype = {article}, author = {Wen, Dingqiao and Yu, Yun and Hahn, Matthew W and Nakhleh, Luay}, journal = {Molecular ecology}, number = {11} }

We, therefore, aimed to determine if PA influenced the effect of bone fragility genetic variants on BMD in childhood. Our sample comprised US children of European ancestry enrolled in the Bone Mineral Density in Childhood Study (N = 918, aged 5 to 19 years, and 52.4\% female). We used a questionnaire to estimate hours per day spent in total, high-, and low-impact PA. We calculated a BMD genetic score (\% BMD lowering alleles) using adult genome-wide association study (GWAS)-implicated BMD variants. We used dual-energy X-ray absorptiometry to estimate femoral neck, total hip, and spine areal-BMD and total body less head (TBLH) bone mineral content (BMC) Z-scores. The BMD genetic score was negatively associated with each bone Z-score (eg, TBLH-BMC: estimate = -0.03, p = 1.3 × 10(-6) ). Total PA was positively associated with bone Z-scores; these associations were driven by time spent in high-impact PA (eg, TBLH-BMC: estimate = 0.05, p = 4.0 × 10(-10) ) and were observed even for children with lower than average bone Z-scores. We found no evidence of PA-adult genetic score interactions (p interaction {\textgreater} 0.05) at any skeletal site, and there was no evidence of PA-genetic score-Tanner stage interactions at any skeletal site (p interaction {\textgreater} 0.05). However, exploratory analyses at the individual variant level revealed that PA statistically interacted with rs2887571 (ERC1/WNT5B) to influence TBLH-BMC in males (p interaction = 7.1 × 10(-5) ), where PA was associated with higher TBLH-BMC Z-score among the BMD-lowering allele carriers (rs2887571 AA homozygotes: estimate = 0.08 [95\% CI 0.06, 0.11], p = 2.7 × 10(-9) ). In conclusion, the beneficial effect of PA on bone, especially high-impact PA, applies to the average child and those genetically predisposed to lower adult BMD (based on GWAS-implicated BMD variants).

We found that the set of meiosis genes shared by Tetrahymena thermophila, Paramecium tetraurelia, Ichthyophthirius multifiliis, and Oxytricha trifallax is consistent with the prevalence of a Mus81-dependent class II crossover pathway that is considered secondary in most model eukaryotes. There is little evidence for a canonical class I crossover pathway that requires the formation of a synaptonemal complex (SC). This gene inventory suggests that meiotic processes in ciliates largely depend on mitotic repair proteins for executing meiotic recombination. We propose that class I crossovers and SCs were reduced sometime during the evolution of ciliates. Consistent with this reduction, we provide microscopic evidence for the presence only of degenerate SCs in Stylonychia mytilus.

Sire mice were treated with EtOH in a concentration range approximating human binge drinking (0-4 g/kg/day EtOH) for 7 weeks and mated with untreated females mice to produce offspring. EtOH exposure to sire mice induced attention deficit hyperactivity disorder (ADHD)-like hyperactive, inattentive, and impulsive behaviors in offspring. As a mechanistic link, both protein and mRNA expression of dopamine transporter (DAT), a key determinant of ADHD-like phenotypes in experimental animals and humans, were significantly decreased by paternal EtOH exposure in cerebral cortex and striatum of offspring mice along with increased methylation of a CpG region of the DAT gene promoter. The increase in methylation of DAT gene promoter was also observed in the sperm of sire mice, suggesting germline changes in the epigenetic methylation signature of DAT gene by EtOH exposure. In addition, the expression of two key regulators of methylation-dependent epigenetic regulation of functional gene expression, namely, MeCP2 and DNMT1, was markedly decreased in offspring cortex and striatum sired by EtOH-exposed mice.

These chromosomal rearrangements often occur at genomic sites susceptible to breakage during DNA replication, including regions with G-quadruplex (G4)-forming potential. G4s are stable secondary structures that guanine-rich single-stranded DNA can readily adopt in vitro. However, their formation in eukaryotic cells has remained elusive and thus a subject of debate ever since they were first described. Recent work has more convincingly implicated G4s in a variety of biological processes including telomere maintenance, gene expression, epigenetic regulation and DNA replication. However, the downside of employing thermodynamically very stable alternative DNA structures as regulatory entities lies in their potential to also interfere with normal DNA metabolic processes, such as transcription and replication, which require readability of each base to faithfully transmit genetic information. Indeed, it has become clear that G4 structures can pose prominent barriers to replication fork progression and that they are also intrinsically recombinogenic.

Co-ordination of polar organelle synthesis, including pili and holdfast, and flagellum ejection, is mediated in part by the scaffolding protein PodJ. At the time of cell division, PodJ undergoes regulated processing to a short form that persists at the flagellar pole of swarmer cells. This study analyses how PodJ's role in structural and signalling protein localization impacts organelle synthesis. A PodJ mutant with an internal deletion exhibits reduced sensitivity to pili-tropic phage ΦCbK, resulting from reduced pilA gene expression, which can be linked to altered signalling protein localization. The phage sensitivity defect of a ΔpodJ mutant can be partially suppressed by ectopic pilA expression. Induction of PodJ processing, by manipulation of podJ itself or controlled perP expression, resulted in decreased pilus biogenesis and, when coupled with a podJ mutation that reduced pilA expression, led to complete loss of phage sensitivity. As a whole, the results show that PodJ's scaffolding role for structural and signalling proteins both contribute to flagellar pole organelle development.}, number = {4}, journal = {Molecular microbiology}, author = {Curtis, Patrick D and Quardokus, Ellen M and Lawler, Melanie L and Guo, Xiaoyun and Klein, David and Chen, Joseph C and Arnold, Randy J and Brun, Yves V}, month = may, year = {2012}, pmid = {22512778}, keywords = {Amino Acid Sequence, Bacterial Proteins, Bacteriophages, Caulobacter crescentus, Cell Division, Fimbriae, Bacterial, Gene expression, Membrane Proteins, Models, Biological, Molecular Sequence Data, Sequence Deletion, Suppression, Genetic}, pages = {712--735} }

RNA G-quadruplexes at these specific locations play important roles in key cellular functions, including telomere homeostasis and gene expression. Indeed, RNA G-quadruplexes appear as important regulators of pre-mRNA processing (splicing and polyadenylation), RNA turnover, mRNA targeting and translation.

Bucindolol is a β-blocker/sympatholytic agent whose efficacy is modulated by polymorphisms in the primary target (β(1) adrenergic receptor [AR] Arg389 Gly on cardiac myocytes) and a secondary target modifier (α(2C) AR Ins [wild-type (Wt)] 322-325 deletion [Del] on cardiac adrenergic neurons). The major allele homozygotes and minor allele carriers of each polymorphism are respectively associated with efficacy enhancement and loss, creating the possibility for genotype combination interactions that can be measured by clinical trial methodology. METHODOLOGY: In a 1,040 patient substudy of a bucindolol vs. placebo heart failure clinical trial, we tested the hypothesis that combinations of β(1)389 and α(2C)322-325 polymorphisms are additive for both efficacy enhancement and loss. Additionally, norepinephrine (NE) affinity for β(1)389 AR variants was measured in human explanted left ventricles. PRINCIPAL FINDINGS: The combination of β(1)389 Arg+α(2C)322-325 Wt major allele homozygotes (47\% of the trial population) was non-additive for efficacy enhancement across six clinical endpoints, with an average efficacy increase of 1.70-fold vs. 2.32-fold in β(1)389 Arg homozygotes+α(2C)322-325 Del minor allele carriers. In contrast, the minor allele carrier combination (13\% subset) exhibited additive efficacy loss. These disparate effects are likely due to the higher proportion (42\% vs. 8.7\%, P = 0.009) of high-affinity NE binding sites in β(1)389 Arg vs. Gly ARs, which converts α(2C)Del minor allele-associated NE lowering from a therapeutic liability to a benefit. CONCLUSIONS: On combination, the two sets of AR polymorphisms 1) influenced bucindolol efficacy seemingly unpredictably but consistent with their pharmacologic interactions, and 2) identified subpopulations with enhanced (β(1)389 Arg homozygotes), intermediate (β(1)389 Gly carriers+α(2C)322-325 Wt homozygotes), and no (β(1)389 Gly carriers+α(2C)322-325 Del carriers) efficacy.}, language = {eng}, number = {10}, journal = {PloS One}, author = {O'Connor, Christopher M. and Fiuzat, Mona and Carson, Peter E. and Anand, Inder S. and Plehn, Jonathan F. and Gottlieb, Stephen S. and Silver, Marc A. and Lindenfeld, JoAnn and Miller, Alan B. and White, Michel and Walsh, Ryan and Nelson, Penny and Medway, Allen and Davis, Gordon and Robertson, Alastair D. and Port, J.

Firstly, RNA-seq data from five tissues and seven developmental stages were assembled into 25,748 gene models. A 3'-end capture and sequencing protocol was developed to predict the 3' ends of transcripts, and 46.1\% of the original models were subsequently refined.

The RNA-seq-only and the Ensembl/VEGA genebuilds contribute contrasting elements to the final genebuild. The RNA-seq genebuild was used to adjust intron/exon boundaries of orthologous defined models, confirm their expression, and improve 3' untranslated regions. Importantly, the inferred protein alignments within the Ensembl genebuild conferred proof of model contiguity for the RNA-seq models.

Whereas a significant proportion of the population will develop "stress-related" conditions such as post-traumatic stress disorder or depression in later life, the majority are considered "resilient" and are able to cope with stress and avoid such psychopathologies. The reason for this heterogeneity is undoubtedly multi-factorial, involving a complex interplay between genetic and environmental factors. Both genes and environment are of critical importance when it comes to developmental processes, and it appears that subtle differences in either of these may be responsible for altering developmental trajectories that confer vulnerability or resilience. At the molecular level, developmental processes are regulated by epigenetic mechanisms, with recent clinical and pre-clinical data obtained by ourselves and others suggesting that epigenetic differences in various regions of the brain are associated with a range of psychiatric disorders, including many that are stress-related.

Using differential RNA sequencing, we have established a genome-wide map of 3,527 transcriptional start sites (TSS) of the model organism Synechocystis sp. PCC6803. One-third of all TSS were located upstream of an annotated gene; another third were on the reverse complementary strand of 866 genes, suggesting massive antisense transcription. Orphan TSS located in intergenic regions led us to predict 314 noncoding RNAs (ncRNAs). Complementary microarray-based RNA profiling verified a high number of noncoding transcripts and identified strong ncRNA regulations. Thus, ∼64\% of all TSS give rise to antisense or ncRNAs in a genome that is to 87\% protein coding. Our data enhance the information on promoters by a factor of 40, suggest the existence of additional small peptide-encoding mRNAs, and provide corrected 5′ annotations for many genes of this cyanobacterium.

By studying promoter sequences of the human ribosomal protein genes we recently identified a novel highly specific Localized Tandem Sequence Motif (LTSM). In this work we sought to identify additional genes and LTSM-binding proteins to elucidate potential regulatory mechanisms. RESULTS: Genome-wide analyses allowed finding a considerable number of additional LTSM-positive genes, the products of which are involved in translation, among them, translation initiation and elongation factors, and 5S rRNA. Electromobility shift assays then showed specific signals demonstrating the binding of protein complexes to LTSM in ribosomal protein gene promoters. Pull-down assays with LTSM-containing oligonucleotides and subsequent mass spectrometric analysis identified the related multifunctional nucleotide binding proteins NonO and SFPQ in the binding complex. Functional characterization then revealed that LTSM enhances the transcriptional activity of the promoters in dependency of the distance from the transcription start site. CONCLUSIONS: Our data demonstrate the power of bioinformatic analyses for the identification of biologically relevant sequence motifs.

This complex process is affected by many factors within cells. Here, we have studied the effect of monovalent cations (K+, Na+, and NH4+) on the outcome of recombination events, as their presence affects the biochemical activities of the proteins involved in recombination as well as the structure of DNA. For this purpose, we used an in vitro recombination system that includes a protein nuclear extract, as a source of recombination machinery, and two plasmids as substrates for intramolecular homologous recombination, each with two copies of different alleles of the human minisatellite MsH43. We found that the presence of monovalent cations induced a decrease in the recombination frequency, accompanied by an increase in the fidelity of the recombination. Moreover, there is an emerging consensus that secondary structures of DNA have the potential to induce genomic instability. Therefore, we analyzed the effect of the sequences capable of forming G-quadruplex on the production of recombinant molecules, taking advantage of the capacity of some MsH43 alleles to generate these kinds of structure in the presence of K+. We observed that the MsH43 recombinants containing duplications, generated in the presence of K+, did not include the repeats located towards the 5'-side of the G-quadruplex motif, suggesting that this structure may be involved in the recombination events leading to duplications.

We initially employed biophysical approach involving CD, UV and FRET to understand the role of polyamines (spermidine and spermine) on conformation, stability, molecular recognition of quadruplex and to investigate the effect of polyamines on quadruplex-Watson Crick duplex transition. Our study demonstrates that polyamines affect the c-MYC quadruplex conformation, perturb its recognition properties and delays duplex formation. The relative free energy difference (DeltaDeltaG degrees) between the duplex and quadruplex structure indicate that polyamines stabilize and favor c-MYC quadruplex over duplex. Further, we investigated the influence of polyamine mediated perturbation of this equilibrium on c-MYC expression. Our results suggest that polyamines induce structural transition of c-MYC quadruplex to a transcriptionally active motif with distinctive molecular recognition property, which drives c-MYC expression.

We aimed to study the genetic and environmental etiology across three measures of activity level: parent and teacher ratings of hyperactivity-impulsivity and actigraph measurements, within a population-based sample of 463 7-9 year old twin pairs. We further examined ways in which the three measures could be combined for future molecular studies. Phenotypic correlations across measures were modest, but a common underlying phenotypic factor was highly heritable (92\%); as was a simple aggregation of all three measurements (77\%).

The term costs often appears in work addressing this issue but may be ambiguously defined. This review distinguishes two conceptually distinct types of costs: phenotypic costs and plasticity costs. Phenotypic costs are assessed from patterns of covariation, typically between a focal trait and a separate trait relevant to fitness. Plasticity costs, separable from phenotypic costs, are gauged by comparing the fitness of genotypes with equivalent phenotypes within two environments but differing in plasticity and fitness. Subtleties associated with both types of costs are illustrated by a body of work addressing predator-induced plasticity. Such subtleties, and potential interplay between the two types of costs, have also been addressed, often in studies involving genetic model organisms. In some instances, investigators have pinpointed the mechanistic basis of plasticity. In this vein, microbial work is especially illuminating and has three additional strengths. First, information about the machinery underlying plasticity--such as structural and regulatory genes, sensory proteins, and biochemical pathways--helps link population-level studies with underlying physiological and genetic mechanisms. Second, microbial studies involve many generations, large populations, and replication. Finally, empirical estimation of key parameters (e.g., mutation rates) is tractable. Together, these allow for rigorous investigation of gene interactions, drift, mutation, and selection--all potential factors influencing the maintenance or loss of inducible traits along with phenotypic and plasticity costs.

In terms of policy solutions, much of the focus of these debates has been on issues of consent, confidentiality and research governance. However, there are broader concerns, such as those associated with commercialisation, which cannot be adequately addressed by these foci. In this article, we focus on the health-wealth benefits that DNA databases promise by considering the views of 10 focus groups on Generation Scotland, Scotland's first national genetic database. As in previous studies, our qualitative research on public/s and stakeholders' views of DNA databases show the prospect of utilising donated samples and information derived for wealth-related ends (i.e. for private profit), irrespective of whether there is an associated health-related benefit, arouses considerable reaction. While health-wealth benefits are not mutually exclusive ideals, the tendency has been to cast 'public' benefits as exclusively health-related, while 'private' commercial benefits for funders and/or researchers are held out as a necessary pay-off. We argue for a less polarised approach that reconsiders what is meant by 'public benefits' and questions the exclusivity of commercial interests. We believe accommodation can be achieved via the mobilisation of a grass roots solution known as 'benefit-sharing' or a 'profit pay-off'.

Properties of the DFE can be inferred by comparing the distributions of the frequencies of segregating nucleotide polymorphisms at selected and neutral sites in a population sample, but demographic changes alter the spectrum of allele frequencies at both neutral and selected sites, so can bias estimates of the DFE if not accounted for. We have developed a maximum-likelihood approach, based on the expected allele-frequency distribution generated by transition matrix methods, to estimate parameters of the DFE while simultaneously estimating parameters of a demographic model that allows a population size change at some time in the past. We tested the method using simulations and found that it accurately recovers simulated parameter values, even if the simulated demography differs substantially from that assumed in our analysis. We use our method to estimate parameters of the DFE for amino acid-changing mutations in humans and Drosophila melanogaster. For a model of unconditionally deleterious mutations, with effects sampled from a gamma distribution, the mean estimate for the distribution shape parameter is approximately 0.2 for human populations, which implies that the DFE is strongly leptokurtic. For Drosophila populations, we estimate that the shape parameter is approximately 0.35.

In species where the inherited structure of social class may lead to consistent resource differences among family lines, between-class variation in resource availability should select for divergence in optimal reproductive strategies. Evaluating this prediction requires information on the phenotypic selection and quantitative genetics of life-history trait variation in relation to individual lifetime access to resources. Here, we show using path analysis how resource availability, measured as the wealth class of the family, affected the opportunity and intensity of phenotypic selection on the key life-history traits of women living in pre-industrial Finland during the 1800s and 1900s. We found the highest opportunity for total selection and the strongest selection on earlier age at first reproduction in women of the poorest wealth class, whereas selection favoured older age at reproductive cessation in mothers of the wealthier classes. We also found clear differences in female life-history traits across wealth classes: the poorest women had the lowest age-specific survival throughout their lives, they started reproduction later, delivered fewer offspring during their lifetime, ceased reproduction younger, had poorer offspring survival to adulthood and, hence, had lower fitness compared to the wealthier women. Our results show that the amount of wealth affected the selection pressure on female life-history in a pre-industrial human population.}, bibtype = {article}, author = {Pettay, Jenni E and Helle, Samuli and Jokela, Jukka and Lummaa, Virpi}, journal = {PloS one}, number = {7} }

Osmoregulatory mechanisms spanning all levels of biological organization, from molecules to behavior, are central to salinity adaptation. Functional genomics and proteomics approaches represent powerful tools for gaining insight into the molecular basis of salinity adaptation and euryhalinity in animals. In this review, we discuss our experience in applying such tools to so-called 'non-model' species, including euryhaline animals that are well-suited for studies of salinity adaptation. Suppression subtractive hybridization, RACE-PCR and mass spectrometry-driven proteomics can be used to identify genes and proteins involved in salinity adaptation or other environmental stress responses in tilapia, sharks and sponges. For protein identification in non-model species, algorithms based on sequence homology searches such as MSBLASTP2 are most powerful. Subsequent gene ontology and pathway analysis can then utilize sets of identified genes and proteins for modeling molecular mechanisms of environmental adaptation. Current limitations for proteomics in non-model species can be overcome by improving sequence coverage, N- and C-terminal sequencing and analysis of intact proteins. Dependence on information about biochemical pathways and gene ontology databases for model species represents a more severe barrier for work with non-model species. To minimize such dependence, focusing on a single biological process (rather than attempting to describe the system as a whole) is key when applying 'omics' approaches to non-model organisms.}, bibtype = {article}, author = {Kültz, Dietmar and Fiol, Diego and Valkova, Nelly and Gomez-Jimenez, Silvia and Chan, Stephanie Y and Lee, Jinoo}, journal = {The Journal of experimental biology}, number = {Pt 9} }

The most devastating species include P. infestans, P. ramorum and P. sojae. In order to develop molecular methods for routinely characterizing their populations and to gain a better insight into the organization and evolution of their genomes, we used an in silico approach to survey and compare simple sequence repeats (SSRs) in transcript sequences from these three species. We compared the occurrence, relative abundance, relative density and cross-species transferability of the SSRs in these oomycetes. RESULTS: The number of SSRs in oomycetes transcribed sequences is low and long SSRs are rare. The in silico transferability of SSRs among the Phytophthora species was analyzed for all sets generated, and primers were selected on the basis of similarity as possible candidates for transferability to other Phytophthora species. Sequences encoding putative pathogenicity factors from all three Phytophthora species were also surveyed for presence of SSRs. However, no correlation between gene function and SSR abundance was observed. The SSR survey results, and the primer pairs designed for all SSRs from the three species, were deposited in a public database. CONCLUSION: In all cases the most common SSRs were trinucleotide repeat units with low repeat numbers. A proportion (7.5%) of primers could be transferred with 90% similarity between at least two species of Phytophthora. This information represents a valuable source of molecular markers for use in population genetics, genetic mapping and strain fingerprinting studies of oomycetes, and illustrates how genomic databases can be exploited to generate data-mining filters for SSRs before experimental validation.}, bibtype = {article}, author = {Garnica, Diana P and Pinzón, Andrés M and Quesada-Ocampo, Lina M and Bernal, Adriana J and Barreto, Emiliano and Grünwald, Niklaus J and Restrepo, Silvia}, journal = {BMC genomics} }

However, the mechanism of ATRA-mediated down-regulation is not well understood. In the present study, deletion analysis and luciferase assays demonstrate that ATRA causes a marked decrease in the activity of the albumin promoter, the region between nt -367 and -167 from the transcription start site, where C/EBP (CCAAT/enhancer-binding protein)-binding sites are tightly packed, is indispensable for ATRA-mediated down-regulation. ChIP (chromatin immunoprecipitation) assays revealed that in vivo binding of C/EBPalpha to the region markedly decreases upon incubation with ATRA, whereas ATRA treatment marginally increases the recruitment of C/EBPbeta. We found that ATRA has the ability to differentially and directly induce expression of a truncated isoform of C/EBPbeta, which is an LIP (liver-enriched transcriptional inhibitory protein) that lacks a transactivation domain, and to increase the binding activity of C/EBPbeta-LIP to its response element. Overexpression of C/EBPbeta-LIP negatively regulates the endogenous expression of albumin, as well as the activity of the albumin promoter induced by C/EBP transactivators such as C/EBPalpha and full-length C/EBPbeta. In conclusion, we propose a novel model for down-regulation of the albumin gene, in which ATRA triggers an increase in the translation of C/EBPbeta-LIP that antagonizes C/EBP transactivators by interacting with their binding sites in the albumin promoter.}, bibtype = {article}, author = {Masaki, Takahiro and Matsuura, Tomokazu and Ohkawa, Kiyoshi and Miyamura, Tatsuo and Okazaki, Isao and Watanabe, Tetsu and Suzuki, Tetsuro}, journal = {The Biochemical journal}, number = {2} }

Transcription factors c-Jun and JunB were among the top-downregulated targets. Restoration of c-Jun expression in preleukemic cells rescued the PU.1 knockdown-initiated myelomonocytic differentiation block.

Examination of human individuals with AML confirmed the correlation between PU.1 and JunB downregulation. These results delineate a transcriptional pattern that precedes leukemic transformation in PU.1-knockdown HSCs and demonstrate that decreased levels of c-Jun and JunB contribute to the development of PU.1 knockdown-induced AML by blocking differentiation and increasing self-renewal.

We demonstrated that exceptional longevity and healthy aging in humans is an inherited phenotype across three generations. Moreover, we demonstrated that subjects with exceptional longevity and their offspring have significantly larger high-density lipoprotein (HDL) levels and particle sizes and low-density lipoprotein (LDL) levels that reflect on their health and cognitive function performance.

Therefore, polymorphism of DNA repair genes may affect the process of carcinogenesis. The importance of genetic variability of the components of mismatch repair (MMR) genes is well documented in colorectal cancer, but little is known about its role in breast cancer. hMSH2 is one of the crucial proteins of MMR. We performed a case-control study to test the association between two polymorphisms in the hMSH2 gene: an A --{\textgreater} G transition at 127 position producing an Asn --{\textgreater} Ser substitution at codon 127 (the Asn127Ser polymorphism) and a G --{\textgreater} A transition at 1032 position resulting in a Gly --{\textgreater} Asp change at codon 322 (the Gly322Asp polymorphism) and breast cancer risk and cancer progression. Genotypes were determined in DNA from peripheral blood lymphocytes of 150 breast cancer patients and 150 age-matched women (controls) by restriction fragment length polymorphism and allele-specific PCR. We did not observe any correlation between studied polymorphisms and breast cancer progression evaluated by node-metastasis, tumor size and Bloom-Richardson grading. A strong association between breast cancer occurrence and the Gly/Gly phenotype of the Gly322Asp polymorphism (odds ratio 8.39; 95\% confidence interval 1.44-48.8) was found. Therefore, MMR may play a role in the breast carcinogenesis and the Gly322Asp polymorphism of the hMSH2 gene may be considered as a potential marker in breast cancer.}, language = {eng}, number = {3}, journal = {Breast Cancer Research and Treatment}, author = {Poplawski, Tomasz and Zadrozny, Marek and Kolacinska, Agnieszka and Rykala, Jan and Morawiec, Zbigniew and Blasiak, Janusz}, month = dec, year = {2005}, pmid = {16252083}, keywords = {Biomarkers, Tumor, Breast Neoplasms, Case-Control Studies, Cell Transformation, Neoplastic, DNA Damage, DNA Repair, Female, Genotype, Humans, Lymphocytes, Middle Aged, MutS Homolog 2 Protein, Phenotype, Point Mutation, Polymorphism, Genetic, Risk Factors, Tumor Markers, Biological}, pages = {199--204}, }

Walsh and A. Gualberto (1992) J. Biol. Chem., 267, 13714-13718], suggesting that tetraplex structures of regulatory sequences of muscle-specific genes could contribute to transcriptional regulation. In the current study we show that promoter or enhancer sequences of various muscle-specific genes display a disproportionately high incidence of guanine clusters. The sequences derived from the guanine-rich promoter or enhancer regions of three muscle-specific genes, human sarcomeric mitochondrial creatine kinase (sMtCK), mouse MCK and alpha7 integrin formed diverse secondary structures. The sMtCK sequence folded into a hairpin structure; the alpha7 integrin oligonucleotide generated a unimolecular tetraplex; and sequences from all three genes associated to generate bimolecular tetraplexes. Furthermore, two neighboring non-contiguous guanine-rich tracts in the alpha7 integrin promoter region also paired to form a tetraplex structure. We also show that homodimeric MyoD bound bimolecular tetraplex structures of muscle-specific regulatory sequences more efficiently than its target E-box motif.

In this report, we compare patterns of LD derived from pairwise measures with statistical estimates of population recombination rates ( rho ) along a 10-Mb stretch of chromosome 20 in four population samples, comprising East Asians, African Americans, and U.K. and U.S. individuals of western European descent.

One requirement for FlbD activity is the assembly of a structure encoded by early, class II flagellar genes. In this report, we show that the trans-acting factor FliX predominantly functions as a negative regulator of FlbD activity in the absence of the class II-encoded flagellar structure. In contrast, a mutant FliX that bypasses the transcriptional requirement for early flagellar assembly is incapable of repressing FlbD in a class II flagellar mutant. Expression of this mutant allele, fliX1, does not alter the temporal pattern of FlbD-dependent transcription. Remarkably, this mutation confers the correct cell cycle timing of hook operon transcription in a strain that cannot assemble the flagellum, indicating that the progression of flagellar assembly is a minor influence on temporal gene expression. Using a two-hybrid assay, we present evidence that FliX regulates FlbD through a direct interaction, a novel mechanism for this class of sigma54 transcriptional activator. Furthermore, increasing the cellular levels of FliX results in an increase in the concentration of FlbD, and a corresponding increase in FlbD-activated transcription, suggesting that FliX and FlbD form a stable complex in Caulobacter. FliX and FlbD homologues are present in several polar-flagellated bacteria, indicating that these proteins constitute an evolutionarily conserved regulatory pair in organisms where flagellar biogenesis is likely to be under control of the cell division cycle.}, number = {3}, urldate = {2009-10-03TZ}, journal = {Molecular Microbiology}, author = {Muir, Rachel E and Gober, James W}, month = nov, year = {2004}, pmid = {15491362}, keywords = {Amino Acid Sequence, Bacterial Proteins, Caulobacter crescentus, DNA-Binding Proteins, Dimerization, Flagella, Gene Expression Regulation, Bacterial, Genes, Bacterial, Genes, Reporter, Membrane Proteins, Molecular Sequence Data, Mutation, Operon, Promoter Regions, Genetic, Sequence Alignment, Transcription, Genetic, Two-Hybrid System Techniques}, pages = {715--730} }

Within this modeling framework, we can allow for missing marker information and for uncertainty about the true underlying genealogy and the makeup of ancestral marker haplotypes. A crucial advantage of our method is the incorporation of the shattered coalescent model for genealogies, allowing for multiple founding mutations at the disease locus and for sporadic cases of disease. Output from the method includes approximate posterior distributions of the location of the disease locus and population-marker haplotype proportions. In addition, output from the algorithm is used to construct a cladogram to represent genetic heterogeneity at the disease locus, highlighting clusters of case chromosomes sharing the same mutation. We present detailed simulations to provide evidence of improvements over existing methodology.

Pairwise comparisons with a set of 15 different populations from neighboring European, North African, and Middle Eastern populations and geographic analysis showed the absence of any significant genetic barrier in the eastern part of the Mediterranean area, suggesting that genetic variation and gene flow in this area follow the "isolation-by-distance" model. These results are in sharp contrast with the observation of a strong north-south genetic barrier in the western Mediterranean basin, defined by the Gibraltar Strait.

This noise comes about in two ways. The inherent stochasticity of biochemical processes such as transcription and translation generates "intrinsic" noise. In addition, fluctuations in the amounts or states of other cellular components lead indirectly to variation in the expression of a particular gene and thus represent "extrinsic" noise. Here, we show how the total variation in the level of expression of a given gene can be decomposed into its intrinsic and extrinsic components. We demonstrate theoretically that simultaneous measurement of two identical genes per cell enables discrimination of these two types of noise. Analytic expressions for intrinsic noise are given for a model that involves all the major steps in transcription and translation. These expressions give the sensitivity to various parameters, quantify the deviation from Poisson statistics, and provide a way of fitting experiment. Transcription dominates the intrinsic noise when the average number of proteins made per mRNA transcript is greater than approximately 2. Below this number, translational effects also become important. Gene replication and cell division, included in the model, cause protein numbers to tend to a limit cycle. We calculate a general form for the extrinsic noise and illustrate it with the particular case of a single fluctuating extrinsic variable-a repressor protein, which acts on the gene of interest.

However, the success of positional cloning attempts based on whole-genome screens has been limited, and many of the fundamental questions relating to the genetic epidemiology of complex human disease remain unanswered. Both to review the success of the positional cloning paradigm as applied to complex human disease and to investigate the characteristics of the whole-genome scans undertaken to date, we created a database of 101 studies of complex human disease, which were found by a systematic Medline search (current as of December 2000). We compared these studies, concerning 31 different human complex diseases, with regard to design, methods, and results. The "significance" categorizations proposed by Lander and Kruglyak were used as criteria for the "success" of a study. Most (66.3% [n=67]) of the studies did not show "significant" linkage when the criteria of Lander and Kruglyak (1995) were used, and the results of studies of the same disease were often inconsistent. Our analyses suggest that no single study design consistently produces more-significant results. Multivariate analysis suggests that the only factors independently associated with increased study success are (a) an increase in the number of individuals studied and (b) study of a sample drawn from only one ethnic group. Positional cloning based on whole-genome screens in complex human disease has proved more difficult than originally had been envisioned; detection of linkage and positional cloning of specific disease-susceptibility loci remains elusive.}, bibtype = {article}, author = {Altmüller, J and Palmer, L J and Fischer, G and Scherb, H and Wjst, M}, journal = {American journal of human genetics}, number = {5} }

To study the possible additional genetic components, we conducted single-locus and two-locus segregation analyses, with and without a polygenic background, using three-generation families ascertained through 858 women with breast cancer diagnosed at age <40 years, ascertained through population cancer registries in Melbourne and Sydney, Australia. Extensive testing for deleterious mutations in BRCA1 and BRCA2, to date, has identified 34 carriers. Our analysis suggested that, after other possible unmeasured familial factors are adjusted for and the known BRCA1 and BRCA2 mutation carriers are excluded, there appears to be a residual dominantly inherited risk of female breast cancer in addition to that derived from mutations in BRCA1 and BRCA2. This study also suggests that there is a substantial recessively inherited risk of early-onset breast cancer. According to the best-fitting model, after excluding known carriers of mutations in BRCA1 and BRCA2, about 1/250 (95% confidence interval [CI] 1/500 to 1/125) women have a recessive risk of 86% (95% CI 69%-100%) by age 50 years and of almost 100% by age 60 years. Possible reasons that our study has implicated a novel strong recessive effect include our inclusion of data on lineal aunts and grandmothers, study of families ascertained through women with early-onset breast cancer, allowance for multiple familial factors in the analysis, and removal of families for whom the cause (i.e., BRCA1 or BRCA2) is known.

The method is highly reliable, and three patterns of peaks (QM376-400, QM780-790 and QM480) appeared to be representative for germ-line polymorphisms, as suggested by the results obtained in nine couples of monozygotic twins and four three-generation families. The frequency of these polymorphic peaks was studied in two different age groups (100 young subjects and 69 centenarians). In two out of the three regions (QM376-400 and QM480) a significant increase in homozygote genotypes frequency was observed in centenarians. These counterintuitive results suggest that increased homozygosity contributes to human longevity. This novel inter-Alu PCR approach could represent a valuable tool to identify longevity-associated DNA sequences interspersed throughout human genome, without making any a priori assumption about their nature and function.}, bibtype = {article}, author = {Bonafe, M and Cardelli, M and Marchegiani, F and Cavallone, L and Giovagnetti, S and Olivieri, F and Lisa, R and Pieri, C and Franceschi, C}, journal = {Exp Gerontol}, number = {7} }

Formation of triplex DNA was monitored by enhanced fluorescence of the beacon, due to the weakening of fluorescence energy transfer, upon its binding to the target duplex. Electrophoretic mobility shift assay confirmed triplex DNA formation by these oligonucleotides. In low salt buffer (10 mM Na(+)), triplex DNA formation was not observed in the absence of a ligand such as spermine. At room temperature (22 degrees C), the equilibrium association constant (K(a)) calculated in the presence of 1 microM spermine and 10 mM Na(+) was 3.2 x 10(8) M(-1). The K(a) value was 1.0 x 10(9) M(-1) in the presence of 150 mM Na(+), and it increased by 10-fold by the addition of 1 mM spermine. Delta H, Delta S, and Delta G of triplex DNA formation, calculated from the temperature dependence of K(a) in the range of 20–45 degrees C, were -35.9 kcal/mol, -77 cal/(mol.K), and -13 kcal/mol, respectively, in the presence of 150 mM NaCl. The corresponding values were -52.9 kcal/mol, -132.5 cal/(mol.K), and -13.4 kcal/mol in the presence of 150 mM NaCl and 1 mM spermine. Structurally related polyamines exerted different degrees of triplex DNA stabilization, as determined by binding constant measurements. Comparison of spermine versus hexamine showed a 17-fold increase in the equilibrium association constant, whereas bis(ethyl) derivatization lead to a 4-fold decrease of this value. In the absence of added duplex and polyamines, the molecular beacon dissociated with a melting temperature of 67 degrees C. Thermodynamic parameters of beacon melting were calculated from the melting curve, and the Delta H, Delta S, and Delta G values were 37.8 kcal/mol, 112 cal/(mol.K), and 4.4 kcal/mol, respectively.

These problems are also associated with early substance use and other markers of behavioral disinhibition. Previous twin research has suggested that much of the covariation between antisocial behavior and alcohol dependence is due to common genetic influences. Similar results have been reported for conduct problems and hyperactivity. For the present study, an adolescent sample consisting of 172 MZ and 162 DZ twin pairs, recruited through the Colorado Twin Registry and the Colorado Longitudinal Twin Study were assessed using standardized psychiatric interviews and personality assessments. DSM-IV symptom counts for conduct disorder and attention deficit hyperactivity disorder, along with a measure of substance experimentation and novelty seeking, were used as indices of a latent behavioral disinhibition trait. A confirmatory factor model fit to individual-level data showed a strong common factor accounting for 16-42\% of the observed variance in each measure. A common pathway model evaluating the genetic and environmental architecture of the latent phenotype suggested that behavioral disinhibition is highly heritable (a(2) = 0.84), and is not influenced significantly by shared environmental factors. A residual correlation between conduct disorder and substance experimentation was explained by shared environmental effects, and a residual correlation between attention deficit hyperactivity disorder and novelty seeking was accounted for by genetic dominance.

We conducted a simulation study to evaluate the probability that a woman with early-onset breast cancer is a mutation carrier, given the number of affected relatives, for a range of plausible values of allele frequency (0.001-0.01), and increased risk in mutation carriers (5-20, equivalent to cumulative risks to age 70 of 25-70%, respectively, for Australian women). Families consisted of a case proband and her mother, sisters, and maternal and paternal grandmothers, and aunts. The numbers of sisters and aunts were generated according to Poisson distributions, and ages were assigned according to a Weibull distribution. The simulated distributions of family history and of the prevalence of mutation carriers among case probands were in general similar to those observed in population-based studies, although there was a suggestion of heterogeneity of breast cancer risk in mutation carriers. As is being observed empirically in population-based samples, a family history of breast cancer was not a strong predictor of mutation status; each affected female relative increased the risk of being a mutation carrier by only 2- to 3-fold.

But a piece of the argument has been missing, and individuals at levels distinct from organisms have been denied potency (although granted existence within the undeniable logic of the theory), because they do not achieve individuality with the same devices used by organisms and therefore seem weak by comparison. We show here that different features define Darwinian individuality across scales of size and time. In particular, species-individuals may develop few emergent features as direct adaptations. The interactor approach works with emergent fitnesses, not with emergent features; and species, as a consequence of their different mechanism for achieving individuality (reproductive exclusivity among subparts, that is, among organisms), express many effects from other levels. Organisms, by contrast, suppress upwardly cascading effects, because the organismic style of individuality (by functional integration of subparts) does not permit much competition or differential reproduction of parts from within. Species do not suppress the operation of lower levels; such effects therefore become available as exaptations conferring emergent fitness-a primary source of the different strength that species achieve as effective Darwinian individuals in evolution.}, bibtype = {article}, author = {Gould, S J and Lloyd, E A}, journal = {Proc Natl Acad Sci U S A}, number = {21} }

Overall, methylation was detected in 11\% of breast cancer cases and in 5\% of ovarian tumours. Methylation of the BRCA1 promoter region was strongly correlated with lack of estrogen and progesterone receptor expression. It is clear from the frequency of abnormal methylation of the BRCA1 promoter region, that this cannot be the sole mechanism mediating the reduced expression of BRCA1 that has previously been reported to occur in the majority of invasive sporadic breast tumours.

The expression patterns of the Abd-B-related Hoxa and Hoxd genes have previously been partially characterized; however, our study reveals that these genes are expressed in patterns more dynamic and complex than generally appreciated, only transiently approximating simple, concentric, nested domains. Detailed analysis of these patterns suggests that the expression of each of the Hoxa and Hoxd genes is regulated in up to three independent phases. Each of these phases appears to be associated with the specification and patterning of one of the proximodistal segments of the limb (upper arm, lower arm and hand). Interestingly, in the last of these phases, the expression of the Hoxd genes violates the general rule of spatial and temporal colinearity of Hox gene expression with gene order along the chromosome. In contrast to the Abd-B-related Hoxa and Hoxd genes, which are expressed in both the fore and hind limbs, different sets of Hoxc genes are expressed in the two limbs. There is a correlation between the relative position of these genes along the chromosome and the axial level of the limb bud in which they are expressed. The more 3' genes are expressed in the fore limb bud while the 5' genes are expressed in the hind limb bud; intermediate genes are transcribed in both limbs. However, there is no clear correlation between the relative position of the genes along the chromosome and their expression domains within the limb. With the exception of Hoxc-11, which is transcribed in a posterior portion of the hind limb, Hoxc gene expression is restricted to the anterior/proximal portion of the limb bud. Importantly, comparison of the distributions of Hoxc-6 RNA and protein products reveals posttranscriptional regulation of this gene, suggesting that caution must be exercised in interpreting the functional significance of the RNA distribution of any of the vertebrate Hox genes. To understand the genesis of the complex patterns of Hox gene expression in the limb bud, we examined the propagation of Hox gene expression relative to cell proliferation. We find that shifts in Hox gene expression cannot be attributed to passive expansion due to cell proliferation. Rather, phase-specific Hox gene expression patterns appear to result from a context-dependent response of the limb mesoderm to Sonic hedgehog. Sonic hedgehog (the patterning signal from the Zone of Polarizing Activity) is known to be able to activate Hoxd gene expression in the limb. Although we find that Sonic hedgehog is capable of initiating and polarizing Hoxd gene expression during both of the latter two phases of Hox gene expression, the specific patterns induced are not determined by the signal, but depend upon the temporal context of the mesoderm receiving the signal. Misexpression of Sonic hedgehog also reveals that Hoxb-9, which is normally excluded from the posterior mesenchyme of the leg, is negatively regulated by Sonic hedgehog and that Hoxc-11, which is expressed in the posterior portion of the leg, is not affected by Sonic hedgehog and hence is not required to pattern the skeletal elements of the lower leg.}, bibtype = {article}, author = {Nelson, C E and Morgan, B a and Burke, a C and Laufer, E and DiMambro, E and Murtaugh, L C and Gonzales, E and Tessarollo, L and Parada, L F and Tabin, C}, journal = {Development (Cambridge, England)}, number = {5} }

Spo0A binds to specific DNA sequences (0A boxes), and two such boxes are found downstream of the tandem promoters for the abrB gene. The data indicate that both RNA polymerase and Spo0A bind simultaneously to a DNA fragment containing the promoters and the 0A boxes.
