Overexpression of microRNAs-155 and 21 targeting mismatch repair proteins in inflammatory bowel diseases

Abstract excerpt

Microsatellite instability (MSI) due to mismatch repair (MMR) deficiency is reported in 5-10% of colorectal cancers (CRCs) complicating inflammatory bowel diseases (IBD). The molecular mechanisms underlying MMR deficiency may be different in IBD CRCs, and in sporadic and hereditary MSI tumors. Here, we hypothesize that overexpression of miR-155 and miR-21, two inflammation-related microRNAs that target core MMR...
