Msh2 and msh6

2011-02-09 Lynch syndrome (LS) is the most common hereditary colorectal cancer syndrome, caused by germline mutations in one of the major genes involved in mismatch repair (MMR): MLH1, MSH2, MSH6 and more rarely, PMS2.Recently, germline deletions in EPCAM have been also associated to the syndrome. Most of the pathogenic MMR mutations found in LS families occur in MLH1 or MSH2. MLH1, MSH2, MSH6 or PMS2 (and EPCAM) •Autosomal dominant •Phenotype not so obvious (unlike FAP, for example) •Family history not always obvious or available •Fortunately, we can use the molecular features of the tumor (mismatch repair deficiency) to help in work-up. 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.

Taken together, we conclude that the low expression of MSH2 and MSH6, involved in the G2/M arrest, results in Cd-induced DNA damage recognition bypassing the MMR system to activate G1/S arrest with the assistance of MLH1. This then leads to repressed root growth in LD10, explaining the intervarietal difference in Cd tolerance in soybean.

Forms two different heterodimers: MutS alpha (MSH2-MSH6 heterodimer) and MutS beta (MSH2-MSH3 heterodimer), which bind to DNA mismatches thereby initiating DNA repair.

Like PMS2, MSH6 only binds with MSH2. Loss of MSH2 function will therefore automatically lead to loss of MSH6 staining, but not vice versa. There are risk management options to detect cancer early or lower the risk to develop cancer.
