Prevalence of DNA Mismatch Repair Deficiencies in Multiple Solid Tumor Types in China. [PDF]

J Evid Based Med
ABSTRACT Aim Microsatellite instability (MSI) as a result of deficient deoxyribonucleic acid (DNA) mismatch repair (dMMR) is a key contributor to the development of tumors with a high mutation rate and cancer‐specific neoantigens. dMMR identification can be beneficial for selection of immune checkpoint inhibitor (ICI) therapy‐eligible patients.

Exome Sequencing Identifies Variants in MLH1 and ERBB2 as Potential Cancer-Predisposing Factors in Familial Early-Onset Colorectal Cancer. [PDF]

Kaohsiung J Med Sci
ABSTRACT Colorectal cancer (CRC) has raised considerable health concerns worldwide, with increasing incidence rates, specifically among younger populations. Despite remarkable progress in diagnosing and treating various diseases, the genetic basis of CRC remains only partially understood.

C-terminal fluorescent labeling impairs functionality of DNA mismatch repair proteins [PDF]

, 2012
The human DNA mismatch repair (MMR) process is crucial to maintain the integrity of the genome and requires many different proteins which interact perfectly and coordinated.

N‐terminus of hMLH1 confers interaction of hMutLα and hMutLβ with hMutSα [PDF]

, 2006
Mismatch repair is a highly conserved system that ensures replication fidelity by repairing mispairs after DNA synthesis. In humans, the two protein heterodimers hMutSα (hMSH2‐hMSH6) and hMutLα (hMLH1‐hPMS2) constitute the centre of the repair reaction ...
