The significance of mismatch repair genes in gastric cancer

DNA mismatch repair genes and colorectal cancer.

Polymorphism of DNA mismatch repair genes in endometrial cancer.

UNLABELLED Endometrial cancer (EC) is the second most common malignancy associated with hereditary non-polyposis colorectal cancer (HNPCC) family. The development of HNPCC is associated with defects in DNA mismatch repair (MMR) pathway resulting in microsatellite instability (MSI). MSI is present in a greater number of EC than can be accounted for by inherited MMR mutations, therefore alternati...

immunohistochemistry stain assessment of dna mismatch repair proteins in gastric cancer

background: germline mutations in mmr genes are reported to be present in more than 70% of hnpcc cases. but, there is a paucity of data regarding the importance of defect of mmr system in the gastric cancer in general. so, in this study, we used ihc stain formlh1,msh2, pms2 andmsh6 to reveal profile ofmmr expression in patients with gastric cancer. materials and methods: this study was performe...

DNA Mismatch Repair (MMR) Genes and Endometrial Cancer

Significance of Dna Mismatch Repair Genes and Microsatellite Instability in Colorectal Carcinoma in Ibadan, Nigeria

Background: Though the incidence of colorectal carcinoma (CRC) is relatively uncommon in Nigeria, compared to the developed countries, recent studies indicate an increasing trend. Our patients often present at an earlier age, which has important implications for the pathogenesis in Nigeria. MLH1, MSH2, MSH6, PMS2 are the commonly mutated MMR genes in descending order of frequency, with PMS1 and...
