Insights into a long life without cancer: The case of the bowhead whale

Molecular Oncology, EarlyView.
Long‐lived, large‐bodied organisms have evolved powerful anticancer mechanisms that preserve cellular and tissue integrity across extended lifespans. A recent study by Firsanov et al. shows that greater genome stability is a key factor underlying the remarkable longevity and cancer resistance of one such species, the bowhead whale.

Association of clinicopathological features with DNA mismatch repair status among colorectal cancer patients presenting to a Tertiary Care Cancer Hospital

International Journal of Advanced Medical and Health Research, 2022
Background: About 12%–15% of sporadic colorectal cancers (CRCs) display a defect in the DNA mismatch repair (MMR) system resulting in microsatellite instability (MSI).

Equilibrium Distribution of Mutators in the Single Fitness Peak Model [PDF]

, 2003
This paper develops an analytically tractable model for determining the equilibrium distribution of mismatch repair deficient strains in unicellular populations. The approach is based on the single fitness peak (SFP) model, which has been used in Eigen's

Strand discrimination in DNA mismatch repair

DNA Repair, 2021
DNA mismatch repair (MMR) corrects non-Watson-Crick basepairs generated by replication errors, recombination intermediates, and some forms of chemical damage to DNA. In MutS and MutL homolog-dependent MMR, damaged bases do not identify the error-containing daughter strand that must be excised and resynthesized.

Does sex of the patient play a role in survival for MSI colorectal cancer? [PDF]

, 2018
Microsatellite instability (MSI) is a feature of colorectal tumors that develops as a result of inactivation of the DNA mismatch repair system. It is found in about 15% of all colorectal cancers and is an important prognostic molecular marker when ...

Homozygous germ-line mutation of the PMS2 mismatch repair gene: a unique case report of constitutional mismatch repair deficiency (CMMRD)

BMC Medical Genetics, 2017
Background Constitutional mismatch repair deficiency syndrome results from bi-allelic inheritance of mutations affecting the key DNA mismatch repair genes: MLH1, MSH2, MSH6 or PMS2.
