Msh2 deficiency attenuates but does not abolish thiopurine hematopoietic toxicity in msh2-/- mice.
The amount of MSH2 protein, a major component of the mismatch repair system, was found to differ >10-fold in leukemia cells from children with newly diagnosed acute lymphoblastic leukemia, with a subgroup of patients (17%) having undetectable MSH2 protein. We therefore used a murine Msh2 knockout model to elucidate the in vivo importance of MSH2 protein expression in determining thiopurine hema...
متن کاملPromoter Methylation of MLH1, PMS2, MSH2 and p16 Is a Phenomenon of Advanced-Stage HCCs
Epigenetic silencing of tumour suppressor genes has been observed in various cancers. Looking at hepatocellular carcinoma (HCC) specific protein silencing was previously demonstrated to be associated with the Hepatitis C virus (HCV). However, the proposed HCV dependent promoter methylation of DNA mismatch repair (MMR) genes and thereby enhanced progression of hepatocarcinogenesis has been the s...
متن کاملA Case of Perimenopausal Endometrial Cancer in a Woman with MSH2 Germline Mutation
Lynch syndrome is a genetic malignancy syndrome affecting the colon, endometrium, and other organs. It is difficult to find a Lynch syndrome patient without any family history of cancer. We have recently examined an endometrial cancer patient with a MSH2 gene mutation without a family history of cancer. A 55-year old Korean woman was admitted to a local clinic for vaginal bleeding. An endometri...
متن کاملEndometrial cancer risk is associated with variants of the mismatch repair genes MLH1 and MSH2.
Women with germ-line mutations in the mismatch repair genes (responsible for hereditary nonpolyposis colorectal cancer) face an increased risk of colonic and endometrial cancer. However, these germ-line mutations are rare and are responsible for fewer than 1% of endometrial cancers. Therefore, we examined whether or not common variants of the hereditary nonpolyposis colorectal cancer-associated...
متن کاملInactivation of the mouse Msh2 gene results in mismatch repair deficiency, methylation tolerance, hyperrecombination, and predisposition to cancer
To investigate the role of the presumed DNA mismatch repair (MMR) gene Msh2 in genome stability and tumorigenesis, we have generated cells and mice that are deficient for the gene. Msh2-deficient cells have lost mismatch binding and have acquired microsatellite instability, a mutator phenotype, and tolerance to methylating agents. Moreover, in these cells, homologous recombination has lost depe...
