Damage to the transforming growth factor TGF-beta type II receptor gene and microsatellite instability in carcinoma cells of the gastrointestinal tract [Povrezhdeniia gena retseptora tipa II transformiruiushchego faktora rosta TGF-beta i mikrosatellitnaia nestabil'nost' genoma v kletkakh kartsinom zheludochno-kishechnogo trakta.] [link]Paper  abstract   bibtex   
In order to compare the frequency of damage to the transforming growth factor TGF-beta receptor type II gene (RII gene) and microsatellite instability (MIN) in oncogenesis of sporadic and hereditary cancer of gastrointestinal tract (GIT), 4 groups of carcinomas were analyzed. They included sporadic gastric (GC), family gastric (FGC), sporadic colorectal (CC) and hereditary nonpolyposis colorectal (HNPCC) carcinomas having appropriate clinical and pathological characteristics. Each group consisted of two types of carcinomas, one of them showing MIN. The RII gene damage occurred in 89% of GC (8 cases out of 9), 86% of CC (6 out of 7), 71% of FGC (5 out of 7), 50% of HNPCC (3 out of 6) for carcinomas coupled with MIN, whereas only in 6% (1 out of 18) of GC and 5% (1 out of 22) of CC for carcinomas without MIN. No damage to RII gene was found in the cases of hereditary carcinomas which did not show MIN though the number of cases analyzed was not sufficient for final conclusions (3 cases of FGC and 3 HNPCC). The data revealed a correlation between the MIN phenotype and mutations in RII gene both for sporadic (p < 0.001) and for hereditary (p < 0.02) cases. For all 4 groups the frequency of RII gene damage was found for early and advanced carcinomas. This suggests that the deficiency of TGF-beta receptor complex in both sporadic and hereditary carcinomas of GIT is revealed at early stages of tumor development and consequently may be responsible for tumor progression. The correlation between RII gene damages and MIN in GIT carcinoma cells suggests that genetic change predetermined the neoplasia of colorectal and gastric epithelium and partially overlapped for both sporadic and hereditary cases.
