Suspected Lynch syndrome associated MSH6 variants: A functional assay to determine their pathogenicity. [PDF]
Lynch syndrome (LS) is a hereditary cancer predisposition caused by inactivating mutations in DNA mismatch repair (MMR) genes. Mutations in the MSH6 DNA MMR gene account for approximately 18% of LS cases. Many LS-associated sequence variants are nonsense

Spatial heterogeneity of hotspot mutations and clonal relatedness in ovarian endometrioid carcinoma
Spatially resolved analysis revealed heterogeneous distributions of selected cancer‐associated mutations within ovarian endometrioid carcinomas. Shared mutations between paired endometrial and ovarian tumors supported clonal relatedness. These findings highlight the value of sampling multiple tumor regions when interpreting molecular profiles ...

Background The DNA in each cell in our body is constantly in danger of becoming damaged. Most DNA damage gets repaired straight away via many different proteins encoded by DNA—repair genes.

ABSTRACT Background The clinical relevance of MGMT promoter methylation in IDH‐mutant gliomas remains controversial in the era of molecular classification. We aimed to systematically evaluate its clinical relevance by integrating quantitative assessment, cutoff exploration, and adjustment for clinical confounding.

Análise do gene MSH6 em pacientes com síndrome de Lynch [PDF]
Entre as síndromes hereditárias de predisposição ao câncer colorretal a Síndrome de Lynch é a síndrome mais frequente, sendo causada por mutações germinativas em um dos principais genes envolvidos na via de reparo de mau pareamento do DNA (MMR): MLH1 ...

This bioinspired acinus‐on‐a‐chip recapitulates VILI pathology, revealing that volutrauma drives P53/NF‐κB pathways while barotrauma triggers mitochondrial‐Wnt dysregulation. A fibrotic transitional cell cluster was identified. Pharmacological interventions targeting these pathways significantly ameliorated injury, establishing a mechanobiological ...

Biochemical Analysis of the Human Mismatch Repair Proteins hMutSα MSH2G674A-MSH6 and MSH2-MSH6T1219D [PDF]
The human MutSalpha protein, a heterodimer between MSH2 and MSH6, initiates DNA mismatch repair (MMR) by recognizing mismatched bases that result from replication errors. Msh2 G674A or Msh6

Abstract Genetic tumor risk syndromes (genturis) contribute substantially to the overall cancer burden and provide opportunities for early detection, prevention, and individualized treatment. Yet, many affected individuals remain undiagnosed due to restrictive testing criteria and challenges in variant interpretation.
