The study included 25 individuals with a confirmed presence of the MLH1 gene mutation with a family history of at least two generations, geographic origin, site of tumour, and other details.

Opens in a new tab or window So we've known for about 20 years that there are these rare cases of early-onset cancer with a high-risk cause, namely constitutional MLH1 methylation. And these ...

At the time of initial (pretreatment) diagnosis, immunohistochemical analysis was performed to detect the expression of MLH1, MSH2, MSH6, and PMS2 (in 12,185 specimens) or MSH6 and PMS2 only (in ...

The qualitative IHC test, VENTANA MMR RxDx, also is designed to assess the various MMR proteins, including MLH1, PMS2, MSH2, and MSH6. The proteins are assessed in formalin-fixed, paraffin-embedded ...

3.4 Seven complete test accuracy studies were identified. These were studies in which people who had IHC or MSI testing, with or without MLH1 promoter hypermethylation testing, went on to have ...

Reconstitution of the activation of the MLH1–MLH3 endonuclease shows how crossovers are formed during meiosis. When DNA breaks, cells use the homologous recombination pathway to accurately ...

In the study, the authors used inducible short hairpin RNA (shRNA) to prevent expression of the gene MLH1, a gene that is part of the DNA mismatch repair system. Here, when the shRNA is induced ...

This group of genes includes MSH2, MSH6 and MLH1. A condition called Lynch syndrome is caused by these genetic changes. Lynch syndrome can increase the risk of various cancers, including prostate ...

As expected, wild-type MLH1 localized primarily to the nucleus (Figure 2A). This localization pattern was also observed for all the MLH1 variants, and we did not detect any protein aggregates. We did, ...
