\n This work focuses on the study of multimeric alpha-lactalbumin oleic acid and lactoferrin oleic acid complexes. The purpose of the research is to study possible mechanisms involved in their pro-apoptotic activities, as seen in some tumor cell cultures. Complexes featuring oleic acid (OA) with human alpha-lactalbumin (hAl) or with bovine alpha-lactalbumin (bAl), and human lactoferrin (hLf) were investigated using small-angle neutron scattering (SANS). It was shown that while alpha-lactalbumin protein complexes were formed on the surface of polydisperse OA micelles, the lactoferrin complexes comprised a monodisperse system of nanoscale particles. Both hAl and hLf complexes appeared to interact with the chromatin of isolated nuclei affecting chromatin structural organization. The possible roles of these processes in the specific anti-tumor activity of these complexes are discussed. © 2019 Elsevier Inc.\n

\n Abstract: Experimental curves of the dependence of survival and delayed colony formation on UV light (254 nm) fluence for two wild-type strains of diploid yeast Saccharomyces cerevisiae capable of recovering from UV damage and their UV-sensitive mutants are presented. The dose–response curves were sigmoid for wild-type cells and rad6/rad6 and rad18/rad18 mutants, which were sensitive to UV irradiation by a factor of 2.2 and 1.5 for survival and 2.0 and 3.1 for delayed colony formation in comparison with the original strain (XS800). The T2 (rad2/rad2) strain was characterized by an exponential dose–response curve and was more sensitive to UV irradiation by a factor of 10.7 for survival and 7.0 for delayed colony formation compared to the original strain (T1). Delayed colony formation of all studied strains reached 100% with increasing UV light fluence. Unlike traditional representations, these data indicate that the delayed colony formation is mainly determined by cell ploidy and does not depend on the shape of the dose–response curves and UV sensitivity of cells. © 2019, Pleiades Publishing, Inc.\n

\n Extracellular vesicles (EV) are secreted by cells of multicellular organisms. EV mediate specific mode of intercellular communication by “horizontal” exchange of substances and information. This phenomenon seems to have an essential biological significance and became a subject of intensive research. Biogenesis, structural and functional EV features are usually studied in vitro. Several methods of EV isolation from cell culture medium are currently used; however, selection of a particular method may have a significant impact on obtained results. The choice of the optimal method is usually determined by the amount of starting biomaterial and the aims of the research. We have performed a comparative analysis of four different methods of EV isolation from cell culture medium: differential ultracentrifugation, ultracentrifugation with 30% sucrose/D 2 O “cushion,” precipitation with plant proteins and latex-based immunoaffinity capturing. EV isolated from several human glial cell lines by different approaches were compared in terms of the following parameters: size, concentration, EV morphology, contamination by non-vesicular particles, content of exosomal tetraspanins on the EV surface, content of total proteins, total RNA, and several glioma-associated miRNAs. The applied methods included nanoparticle tracking analysis (NTA), dynamic light scattering (DLS), cryo-electron microscopy, flow cytometry and RT-qPCR. Based on the obtained results, we have developed practical recommendations that may help researchers to make the best choice of the EV isolation method. © 2018, Pleiades Publishing, Ltd.\n

\n Extracellular vesicles (EV) are secreted by cells of multicellular organisms. EV mediate specific mode of intercellular communication by \"horizontal\" exchange of substances and information. This phenomenon seems to have an essential biological significance and became a subject of intensive research. Biogenesis, structural and functional features of the EV is being commonly studies in in vitro condition. Several methods of EV isolation from cell culture medium are established, however selection of method might influence on obtained results. The choice of the optimal method depends usually from the amount of medium and the aims of the research while is still challenging issue. We performed a comparative analysis of four different methods of EV isolation from cell culture medium: differential ultracentrifugation, ultracentrifugation with a 30% sucrose/D2O \"cushion\", precipitation with plant proteins and immune-affinity capturing. EV isolated by different approaches were compared in terms of following parameters: size, concentration, morphology of EV, contamination by non-vesicular particles, content of exosomal tetraspanins on the EV surface, content of total proteins, RNA, and several glioma-associated miRNAs. Applied methods included nano-patricle tracking analysis (NTA), dynamic light scattering (DLS), cryo-electron microscopy, flow cytometry and RT-qPCR.

Here, we demonstrated that there is activation of expression of the p21/Waf1 gene when the cells were treated with sodium butyrate (NaBu), which is a natural histone deacetylase inhibitor, and investigated whether this phenomenon depends on the presence of a functionally active TP53 protein. For this purpose, we compared the effect of NaBu treatment of human cell lines with different TP53 mutation profiles, including wild-type TP53, single nucleotide substitutions, and the complete absence of the TP53 gene. NaBu activated the TP53 protein via hyperacetylation at the lysine residue K382, without significant changes in the level of protein expression. Western blotting showed that the addition of NaBu triggers a significant increase in the p21/Waf1 protein level in both TP53 wild-type cells and in cells with single nucleotide substitutions in the central DNA-binding core domain (DBD) of the TP53 protein. At the same time, no p21/Waf1 protein induction was observed in cells with complete deletion of the TP53 gene.

\n The p21/Waf1 protein is one of the main regulators of cell cycle arrest and one of the best-known transcriptional targets of the TP53 protein. Here, we demonstrated that there is activation of expression of the p21/Waf1 gene when the cells were treated with sodium butyrate (NaBu), which is a natural histone deacetylase inhibitor, and investigated whether this phenomenon depends on the presence of a functionally active TP53 protein. For this purpose, we compared the effect of NaBu treatment of human cell lines with different TP53 mutation profiles, including wild-type TP53, single nucleotide substitutions, and the complete absence of the TP53 gene. NaBu activated the TP53 protein via hyperacetylation at the lysine residue K382, without significant changes in the level of protein expression. Western blotting showed that the addition of NaBu triggers a significant increase in the p21/Waf1 protein level in both TP53 wild-type cells and in cells with single nucleotide substitutions in the central DNA-binding core domain (DBD) of the TP53 protein. At the same time, no p21/Waf1 protein induction was observed in cells with complete deletion of the TP53 gene. However, NaBu was not able to induce p21/Waf1 production when the expression of TP53 was transiently knocked down by the p53 siRNA. Overall, our results suggest that NaBu-dependent induction of p21/Waf1 does require the presence of TP53 protein, but, unexpectedly, it can occur regardless of mutational changes in the domain responsible for the TP53 binding to DNA.

The lethal effect of UV radiation was inhibited when the preparation preparation MFA was used on complete medium with ethanol. MPA had no effect on replicative mutagenesis. At the same time it depressed mutagenesis caused by repair errors. The data obtained suggest the antimutagenic activity of multiphytoadaptogene is associated with postreplicative repair activation. © 2013 Pleiades Publishing, Inc.\n

Here we describe a novel, evolutionarily conserved, ISWI-containing complex termed ToRC (Toutatiscontaining chromatin remodeling complex). ToRC comprises ISWI, Toutatis/TIP5 (TTF-I-interacting protein 5), and the transcriptional corepressor CtBP (C-terminal-binding protein). ToRC facilitates ATP-dependent nucleosome assembly in vitro. All three subunits are required for its maximal biochemical activity. The toutatis gene exhibits strong synthetic lethal interactions with CtBP. Thus, ToRC mediates, at least in part, biological activities of CtBP and Toutatis. ToRC subunits colocalize in euchromatic arms of polytene chromosomes. Furthermore, nuclear localization and precise distribution of ToRC in chromosomes are dependent on CtBP. ToRC is involved in CtBP-mediated regulation of transcription by RNA polymerase II in vivo. For instance, both Toutatis and CtBP are required for repression of genes of a proneural gene cluster, achaete-scute complex (AS-C), in Drosophila larvae.

\n SNF2-like motor proteins, such as ISWI, cooperate with histone chaperones in the assembly and remodeling of chromatin. Here we describe a novel, evolutionarily conserved, ISWI-containing complex termed ToRC (Toutatiscontaining chromatin remodeling complex). ToRC comprises ISWI, Toutatis/TIP5 (TTF-I-interacting protein 5), and the transcriptional corepressor CtBP (C-terminal-binding protein). ToRC facilitates ATP-dependent nucleosome assembly in vitro. All three subunits are required for its maximal biochemical activity. The toutatis gene exhibits strong synthetic lethal interactions with CtBP. Thus, ToRC mediates, at least in part, biological activities of CtBP and Toutatis. ToRC subunits colocalize in euchromatic arms of polytene chromosomes. Furthermore, nuclear localization and precise distribution of ToRC in chromosomes are dependent on CtBP. ToRC is involved in CtBP-mediated regulation of transcription by RNA polymerase II in vivo. For instance, both Toutatis and CtBP are required for repression of genes of a proneural gene cluster, achaete-scute complex (AS-C), in Drosophila larvae. Intriguingly, native C-terminally truncated Toutatis isoforms do not associate with CtBP and localize predominantly to the nucleolus. Thus, Toutatis forms two alternative complexes that have differential distribution and can participate in distinct aspects of nuclear DNA metabolism. © 2012 by Cold Spring Harbor Laboratory Press.\n

\n The yeast genes IXR1 and HMO1 encode proteins belonging to the family of chromatin nonhistone proteins, which are able to recognize and bind to irregular DNA structures. The full deletion of gene IXR1 leads to an increase in cell resistance to the lethal action of UV light, γ-rays, and MMS, increases spontaneous mutagenesis and significantlly decreases the level of UV-induced mutations. It was earlier demonstrated in our works that the hmo1 mutation renders cells sensitive to the lethal action of cisplatin and virtually does not affect the sensitivity to UV light. Characteristically, the rates of spontaneous and UV-induced mutagenesis in the mutant are increased. Epistatic analysis of the double mutation hmo1 ixr1 demonstrated that the interaction of these genes in relation to the lethal effect of cisplatin and UV light, as well as UV-induced mutagenesis, is additive. This suggests that the products of genes HMO1 and IXR1 participate in different repair pathways. The ixr1 mutation significantly increases the rate of spontaneous mutagenesis mediated by replication errors, whereas mutation hmo1 increases the rate of repair mutagenesis. In wild-type cells, the level of spontaneous mutagenesis was nearly one order of magnitude lower than that obtained in cells of the double mutant. Consequently, the combined activity of the Hmo1 and the Ixr1 proteins provides efficient correction of both repair and replication errors. © 2010 Pleiades Publishing, Ltd.\n

\n This work provides evidence that the product of the RDH54 gene participates in the coordination of some repair pathways of DNA lesions. The unique point mutation rdh54-29 described in our previous works confers the phenotype markedly differing from that of the strain with a full deletion of gene RDH54. The epistatic type of interaction between mutations rdh 54-29 and apn 1Δ allowed the product of gene RDH54 to be attributed to the base excision repair pathway. However, a pleiotropic effect of mutation rdh54-29 manifested as sensitivity to a wide spectrum of DNA-damagi ng agents suggests that Rdh54 is involved in the regulation of several DNA repair pathways. To verify this hypothesis, the direct influence of mutation rdh54-29 on recombination and mutagenesis was evaluated. The results obtained led to the assumption that, in addition to the involvement in base excision repair, Rdh54p may play a certain role in the coordination of DNA lesion repair by various systems, including recombinational and mutagenic repair pathways or nucleotide excision repair. This function supposedly is mediated through modification of chromatin structure at the location of DNA lesion, in particular, by alleviation of DNA-histone bonds, thus rendering DNA more susceptible to the action of various repair proteins. © Pleiades Publishing, Inc., 2010.\n

Previously, we isolated rdh54-29 point mutation demonstrating unique properties different from the full deletion of RDH54 gene. Epistatic interaction between rdh54-29 and apn1delta mutations discloses the function of Rdh54p in the process of base excision repair. However, rdh54-29 mutant exhibits sensitivity to many DNA damaging agents including UV light, methylmethanesulphonate and nitrous acid. Such pleiotrophic effect of rdh54-29 mutation may indicate the role of Rdh54p in the regulation of different DNA repair systems.

\n In this work, we present the evidences of the involvement of Rdh54 in coordination of DNA repair by several pathways. Previously, we isolated rdh54-29 point mutation demonstrating unique properties different from the full deletion of RDH54 gene. Epistatic interaction between rdh54-29 and apn1delta mutations discloses the function of Rdh54p in the process of base excision repair. However, rdh54-29 mutant exhibits sensitivity to many DNA damaging agents including UV light, methylmethanesulphonate and nitrous acid. Such pleiotrophic effect of rdh54-29 mutation may indicate the role of Rdh54p in the regulation of different DNA repair systems. To check this hypothesis, we estimated the effect of rdh54-29 mutation on recombination and mutagenesis. The data confirm the involvement of Rdh54p in coordination of different DNA repair systems including mutagenic and recombinagenic pathways as well as nucleotide excision repair. Rdh54p presumably operates via chromatin remodulation at the site of damage rendering DNA accessible to the DNA repair enzymes.\n

\n DNA double-strand break (DSB) repair mediated by the Rad51 pathway of homologous recombination is conserved in eukaryotes. In yeast, Rad51 paralogs, Saccharomyces cerevisiae Rad55-Rad57 and Schizosaccharomyces pombe Rhp55-Rhp57, are mediators of Rad51 nucleoprotein formation. The recently discovered S. pombe Sfr1/Dds20 protein has been shown to interact with Rad51 and to operate in the Rad51-dependent DSB repair pathway in parallel to the paralog-mediated pathway. Here we show that Sfr1 is a nuclear protein and acts downstream of Rad50 in DSB processing. sfr1δ is epistatic to rad18- and rad60-, and Sfr1 is a high-copy suppressor of the replication and repair defects of a rad60 mutant. Sfr1 functions in a Cds1-independent UV damage tolerance mechanism. In contrast to mitotic recombination, meiotic recombination is significantly reduced in sfr1δ strains. Our data indicate that Sfr1 acts in DSB repair mainly outside of S-phase, and is required for wild-type levels of meiotic recombination. We suggest that Sfr1 acts early in recombination and has a specific role in Rad51 filament assembly, distinct from that of the Rad51 paralogs. © Springer-Verlag 2008.\n

\n A new DNA repair gene from fission yeast Schizosaccharomyces pombe rlp1+ (RecA-like protein) has been identified. Rlp1 shows homology to RecA-like proteins, and is the third S. pombe Rad51 paralog besides Rhp55 and Rhp57. The new gene encodes a 363 aa protein with predicted Mr of 41,700 and has NTP-binding motif. The rlp1Δ mutant is sensitive to methyl methanesulfonate (MMS), ionizing radiation (IR), and camptothecin (CPT), although to a lesser extent than the deletion mutants of rhp55+ and rhp51+ genes. In contrast to other recombinational repair mutants, the rlp1Δ mutant does not exhibit sensitivity to UV light and mitomycin C (MMC). Mitotic recombination is moderately reduced in rlp1 mutant. Epistatic analysis of MMS and IR-sensitivity of rlp1Δ mutant indicates that rlp1+ acts in the recombinational pathway of double-strand break (DSB) repair together with rhp51+, rhp55+, and rad22 + genes. Yeast two-hybrid analysis suggests that Rlp1 may interact with Rhp57 protein. We propose that Rlp1 have an accessory role in repair of a subset of DNA damage induced by MMS and IR, and is required for the full extent of DNA recombination and cell survival under condition of a replication fork collapse. © 2004 Elsevier B.V.

\n The terminal DNA arrays on chromosomes of Drosophila melanogaster are composed of two families of non-LTR retrotransposons, HeT-A and TART. Available evidence suggests that chromosome length in this species and its close relatives is maintained by targeted transposition of these elements, with attachment of the elements to the chromosome end by their 3′ oligo(A) tails. However, the regulation of transposition of these elements and the control of telomere length are poorly understood. Here we present the hypothesis that the forces involved in telomere length regulation in Drosophila are the underlying forces that manifest themselves as telomeric position effect (TPE). Based on recent studies of TPE, which found that expression of a reporter gene is influenced by telomere structure in cis and trans, we propose that the subtelomeric satellite (TAS) in D. melanogaster plays an important role in controlling telomere elongation. Transcription of a HeT-A element is probably initiated at a promoter in the 3′ UTR of an upstream element, and TAS may repress this transcriptional activity in cis and trans. A region of HeT-A not at the extreme 3′ end of the element may act as a transcriptional enhancer that may be modulated by TAS.\n

\n Chromosome length in Drosophila is maintained by the targeted transposition of two families of non-LTR retrotransposons, HeT-A and TART. Although the rate of transposition to telomeres is sufficient to counterbalance loss from the chromosome ends due to incomplete DNA replication, transposition as a mechanism for elongating chromosome ends raises the possibility of damaged or deleted telomeres, because of its stochastic nature. Recent evidence suggests that HeT-A transposition is controlled at the levels of transcription and reverse transcription. HeT-A transcription is found primarily in mitotically active cells, and transcription of a w+ reporter gene inserted into the 2L telomere increases when the homologous telomere is partially or completely deleted. The terminal HeT-A array may be important as a positive regulator of this activity in cis, and the subterminal satellite appears to be an important negative regulator in cis. A third chromosome modifier has been identified that increases the level of reverse transcriptase activity on a HeT-A RNA template and greatly increases the transposition of HeT-A. Thus, the host appears to play a role in transposition of these elements. Taken together, these results suggest that control of HeT-A transposition is more complex than previously thought.\n

Mutations in this gene lead to the formation of the mutator phenotype and high sensitivity to induced mutagenesis. The double rad2 himl mutant manifested the synergic type of interaction. The level of UV-induced mutagenesis in the double mutant was five times higher than in single mutants, and the absolute yield of forward mutations in five genes controlling adenine biosynthesis was 1 to 2%. UV-induced mutagenesis was increased, at low doses, by several orders of magnitude in the double mutant, compared to the wild-type strain. The high level of mutagenesis in this mutant was caused by ethyl and methyl methanesulfonate. These properties of the stock with the double rad.2 himl mutation makes it promising as a tester in analysis of the gene toxicity of different substances.\n

\n Genetic content of 44F2-3; 4505-6 region of chromosome 2 characterized by an increased portion of heterochromatin rearrangements in comparison with other radiation-induced mutations, was studied. Eighteen complementation groups of lethal and viability reducing mutations were identified in 14 consecutive subregions of 44F-3; 4505-6 region using deletion and complementation analysis. Four additional complementation groups were formed only by rearrangements of heterochromatin. Location of heterochromatic aberrations does not coincide with hot spots of intralocus mutagenesis. Effective lethal period of mutations in 44F2-3; 45C5-6 region were analyzed. Mutations in 5 loci are lethal at the embryonic stage, strict lethal mutations of other genes lead to death at the larval stage. Mutations specifically changing scale and form of certain thorax bristles were identified in haplosensitive Notopleural locus which was not characterized earlier. Phenotypes of individuals homozygous for nonstrictly lethal alleles of vital loci of the region 44F-45C were described.\n

Six mutants have been isolated and designated him (high induced mutagenesis), and 4 of them were studied in more detail. The him mutants displayed enhanced reversion of the ade2-42 allele, either spontaneous or induced by nitrous acid, UV light, and the base analog 6-N-hydroxylaminopurine, but not by γ-irradiation. It is worth noting that the him mutants turned out not to be sensitive to the lethal effects of the mutagens used. The enhancement in mutation induced by nitrous acid, UV light, and 6-N-hydroxylaminopurine has been confirmed in a forward-mutation assay (induction of mutations in the ADE1, ADE2 genes). The latter agent revealed the most apparent differences between the him mutants and the wild-type strain and was, therefore, chosen for the genetic analysis of mutants. him mutations analyzed behaved as a single Mendelian trait; complementation tests indicated 3 complementation groups (HIM1, HIM2, and HIm3), each containing 1 mutant allele. Uracil-DNA glycosylase activity was determined in crude cell extracts, and no significant differences between the wild-type and him strains detected. Spontaneous mitotic gene conversion at the ADE2 locus is altered in him1 strains, either increased or decreased, depending on the particular heteroallelic combination. Genetic evidence strongly suggests him mutations to be involved in a process of mismatch correction of molecular heteroduplexes. © 1989.},\r\nauthor_keywords={Enhanced mutagenesis;  Mitotic gene conversion;  S. cerevisiae},\r\ncorrespondence_address1={Ivanov, E.L.; B.P.

\n We have developed a method to isolate yeast (Saccharomyces cerevisiae) mutants with enhanced induced mutagenesis based on nitrous acid-induced reversion of the ade2-42 allele. Six mutants have been isolated and designated him (high induced mutagenesis), and 4 of them were studied in more detail. The him mutants displayed enhanced reversion of the ade2-42 allele, either spontaneous or induced by nitrous acid, UV light, and the base analog 6-N-hydroxylaminopurine, but not by γ-irradiation. It is worth noting that the him mutants turned out not to be sensitive to the lethal effects of the mutagens used. The enhancement in mutation induced by nitrous acid, UV light, and 6-N-hydroxylaminopurine has been confirmed in a forward-mutation assay (induction of mutations in the ADE1, ADE2 genes). The latter agent revealed the most apparent differences between the him mutants and the wild-type strain and was, therefore, chosen for the genetic analysis of mutants. him mutations analyzed behaved as a single Mendelian trait; complementation tests indicated 3 complementation groups (HIM1, HIM2, and HIm3), each containing 1 mutant allele. Uracil-DNA glycosylase activity was determined in crude cell extracts, and no significant differences between the wild-type and him strains detected. Spontaneous mitotic gene conversion at the ADE2 locus is altered in him1 strains, either increased or decreased, depending on the particular heteroallelic combination. Genetic evidence strongly suggests him mutations to be involved in a process of mismatch correction of molecular heteroduplexes. © 1989.\n
