Expression of the human mismatch repair gene hMSH2 in normal and neoplastic tissues.
Hereditary nonpolyposis colorectal cancer is caused by inherited mutations of mismatch repair genes. We developed monoclonal antibodies to the prototype human mismatch repair gene hMSH2 and used them to detect an immunoreactive protein of M(r) 100,000 in mismatch-proficient cell lines. In addition, a M(r) 150,000 protein coimmunoprecipitated with the hMSH2 gene product in cell lines expressing ...
متن کاملHuman exonuclease I interacts with the mismatch repair protein hMSH2.
DNA mismatch repair (MMR) plays a vital role in the faithful replication of DNA, and its inactivation leads to a mutator phenotype that has been associated with the common cancer susceptibility syndrome Hereditary Non-Polyposis Colorectal Cancer (HNPCC). Here, we report on a novel human exonuclease (hExoI) that is related to the yeast exonuclease 1. The hExoI cDNA comprises 2541 bp, which code ...
متن کاملExpression of hMSH2 protein of the human DNA mismatch repair system in oral lichen planus
Lichen planus is a mucocutaneous disease of inflammatory nature and unknown etiology. It is characterized by a cell-mediated immunological response to induced antigenic change in skin and/or mucosa. The possible malignant transformation of lichen planus remains a subject of controversial discussions in the literature. hMSH2 is one of the human DNA mismatch repair (hMMR) genes and it plays an im...
متن کاملDifferential involvement of the human mismatch repair proteins, hMLH1 and hMSH2, in transcription-coupled repair.
Defects in DNA mismatch repair have been associated with both hereditary and sporadic forms of cancer. Recently, it has been shown that human cell lines deficient in mismatch repair were also defective in the transcription-coupled repair (TCR) of UV-induced DNA damage. We examined whether TCR of ionizing radiation-induced DNA damage also requires the genes involved in DNA mismatch repair. Cells...
متن کاملExpression of human DNA mismatch-repair protein, hMSH2, in patients with oral lichen planus
hMSH2 is one of the human DNA mismatch repair genes that plays an important role in reducing mutations and maintaining genomic stability. The aim of the present study was to detect the expression and significance of hMSH2 protein in patients with oral lichen planus (OLP). The expression levels of hMSH2 in the OLP group (n=51) and control group with normal oral mucosa (NM; n=40) were detected us...
