The DNA mismatch repair (MMR) pathway maintains genomic stability and
reduces cancer risk (colorectal and other internal cancers) by correcting polymerase
errors and activating cell cycle checkpoints and apoptosis in response to DNA damage.
Few studies have examined the influence of commonly encountered environmental
mutagens/carcinogens on the etiology of MMR-deficient...
Mismatch repair (MMR) system performs mainly three roles to maintain
genomic stability, correct DNA biosynthetic errors, ensure the fidelity of
genetic recombination, and in mammalian cells participate in the cellular
response to some DNA damages. Deficiencies in mismatch repair increase
mutation rates and cancer risks. In eukaryotes, the MMR system...
DNA mismatch repair (MMR) is an evolutionary conserved process that functions to maintain genomic integrity through the correction of mismatches that have escaped proofreading. Mutations in the MMR gene Mlh1 are associated with approximately 50% of all cases of Lynch syndrome, a hereditary predisposition to colorectal cancer, through varying and...
