Review of the application of dMMR and microsatellite instability in the diagnosis and treatment of endometrial cancer

open access: yesAnnals of Oncology Research and Therapy, 2021
Mismatch repair genes are responsible for discovering and repairing base mismatches during DNA replication in cells. Defects in mismatch repair function will lead to accumulation of gene mutations, microsatellite instability, and ultimately tumorigenesis.

ATP-Dependent Mismatch Recognition in DNA Replication Mismatch Repair

open access: yesQuantum Reports, 2023
Mismatch repair is a critical step in DNA replication that occurs after base selection and proofreading, significantly increasing fidelity. However, the mechanism of mismatch recognition has not been established for any repair enzyme.

Expression of PD-L1 in Microsatellite Instability High Tumours: A Retrospective Study [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2023
Introduction: Microsatellite Instability (MSI) is the hallmark of Lynch syndrome/Constitutional Mismatch Repair Deficiency (CMMRD) and is also found in many sporadic cancers like colorectal cancer, endometrial, gastric, small intestine, urothelial ...

MMR markers correlate with clinical outcome in patients with esophageal squamous cell carcinoma

open access: yesThe International Journal of Biological Markers, 2023
Background The DNA mismatch repair system is one of the defense mechanisms in the body, and the inactivation of mismatch repair plays a pivotal role in secondary carcinogenesis and progression.

The rate of spontaneous mutations in yeast deficient for MutSβ function

open access: yesG3: Genes, Genomes, Genetics, 2022
Mutations in simple sequence repeat loci underlie many inherited disorders in humans, and are increasingly recognized as important determinants of natural phenotypic variation.

Prime editing efficiency and fidelity are enhanced in the absence of mismatch repair

open access: yesNature Communications, 2022
Prime Editing is a versatile genome engineering tool. Here, the authors identify the DNA repair pathway known as mismatch repair as inhibitory for Prime Editing, thus, loss of mismatch repair enhances the efficiency of Prime Editing.

The Startling Role of Mismatch Repair in Trinucleotide Repeat Expansions

open access: yesCells, 2021
Trinucleotide repeats are a peculiar class of microsatellites whose expansions are responsible for approximately 30 human neurological or developmental disorders.

Constitutional mismatch repair deficiency and childhood leukemia/lymphoma – report on a novel biallelic MSH6 mutation

open access: yesHaematologica, 2010
Biallelic mutations of mismatch repair genes cause constitutional mismatch repair deficiency associated with an increased risk for childhood leukemia/lymphoma.

An Msh3 ATPase domain mutation has no effect on MMR function

open access: yesBMC Research Notes, 2017
Objective To demonstrate that the Msh3 ATPase domain is required for DNA mismatch repair and tumor suppression in a murine model. Results The DNA mismatch repair proteins are members of the ABC family of ATPases.

Explosive mutation accumulation triggered by heterozygous human Pol ε proofreading-deficiency is driven by suppression of mismatch repair

open access: yeseLife, 2018
Tumors defective for DNA polymerase (Pol) ε proofreading have the highest tumor mutation burden identified. A major unanswered question is whether loss of Pol ε proofreading by itself is sufficient to drive this mutagenesis, or whether additional factors
