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

Nature 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.

DNA mismatch repair proteins: scientific update and practical guide

Journal of Clinical Pathology, 2021
DNA mismatch repair (MMR) proteins are essential for the recognition and correction of sporadic genetic mutations that occur during DNA replication. Deficient MMR function (dMMR) leads to an increased risk of development of neoplasia.

Alleviation of C⋅C Mismatches in DNA by the Escherichia coli Fpg Protein

Frontiers in Microbiology, 2021
DNA polymerase III mis-insertion may, where not corrected by its 3′→ 5′ exonuclease or the mismatch repair (MMR) function, result in all possible non-cognate base pairs in DNA generating base substitutions.

Strand asymmetry influences mismatch resolution during a single-strand annealing

Genome Biology, 2022
Background Biases of DNA repair can shape the nucleotide landscape of genomes at evolutionary timescales. The molecular mechanisms of those biases are still poorly understood because it is difficult to isolate the contributions of DNA repair from those ...

Non-homologous end-joining pathway associated with occurrence of myocardial infarction: gene set analysis of genome-wide association study data [PDF]

, 2013
<p>Purpose: DNA repair deficiencies have been postulated to play a role in the development and progression of cardiovascular disease (CVD). The hypothesis is that DNA damage accumulating with age may induce cell death, which promotes formation of ...

Immune Checkpoint Inhibitors in Tumors Harboring Homologous Recombination Deficiency: Challenges in Attaining Efficacy

Frontiers in Immunology, 2022
Cancer cells harbor genomic instability due to accumulated DNA damage, one of the cancer hallmarks. At least five major DNA Damage Repair (DDR) pathways are recognized to repair DNA damages during different stages of the cell cycle, comprehending base ...

Downregulation of both mismatch repair and non-homologous end-joining pathways in hypoxic brain tumour cell lines [PDF]

PeerJ, 2021
Glioblastoma, a grade IV astrocytoma, has a poor survival rate in part due to ineffective treatment options available. These tumours are heterogeneous with areas of low oxygen levels, termed hypoxic regions.

Error-free and error-prone DNA repair gene expression data through reprogramming and passage in human iPS cells

Data in Brief, 2020
We recently found that DNA repair-related gene expression could be altered by reprogramming as well as the increased expression of genes that accurately convey genomic information, such as homologous recombination (HR) and mismatch repair (MMR), and the ...

An Msh3 ATPase domain mutation has no effect on MMR function

BMC 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.
