Molecular mechanisms of cancer predisposition in HNPCC

MLH-1 and MSH2 are involved in the DNA mismatch repair (MMR) process. Microsatellite instability (MSI) is an alteration of microsatellite repeats during DNA replication and is a hallmark of the inactivation of the MMR genes.

This inducible response occurs immediately after alky-lation, is long-lasting and dose-dependent, and results from translocation of the preformed MutSa complex (composed of MSH2 and MSH6) from the cytoplasm into the nucleus. Lynch Syndrome (LS) is the most common dominantly inherited colorectal cancer (CRC) predisposition and is caused by a heterozygous germline defect in one of the DNA mismatch repair (MMR) genes MLH1, MSH2, MSH6, or PMS2.

The results indicate that S. cerevisiae has two pathways of MSH2-dependent mismatch repair: one that recognizes single-base mispairs and requires MSH2 and MSH6, and a second that recognizes insertion/deletion mispairs and requires a combination of either MSH2 and The MSH6 gene provides instructions for making a protein that plays an essential role in repairing DNA. This protein helps fix errors that are made when DNA is copied (DNA replication) in preparation for cell division. The MSH6 protein joins with another protein called MSH2 (produced from the MSH2 gene MSH6 is a heterodimer of MSH2 and binds to DNA containing G/T mismatches. MLH-1 and MSH2 are involved in the DNA mismatch repair (MMR) process. Microsatellite instability (MSI) is an alteration of microsatellite repeats during DNA replication and is a hallmark of the inactivation of the MMR genes. These defects in MMR have been related to human carcinogenesis. Studies have shown the mutations MSH2 and/or MSH6 alterations are associated with a significantly higher TMB than MLH1 and/or PMS2 across several cancer types. TMB varies significantly across MSI-H tumors.
