Base excision repair imbalance in colorectal cancer has prognostic value and modulates response to chemotherapy
Colorectal cancer (CRC) is prevalent worldwide, and treatment often involves surgery and genotoxic chemotherapy. DNA repair mechanisms, such as base excision repair (BER) and mismatch repair (MMR), may not only influence tumour characteristics and prognosis but also dictate chemotherapy response. Defective MMR contributes to chemoresistance in colorectal cancer. Moreover, BER affects cellular s...
متن کاملDysregulated Expression and Sub cellular Localization of Base Excision Repair (BER) Pathway Enzymes in Gallbladder Cancer
Base excision repair (BER) pathway is one of the repair systems that have an impact on the radiotherapy and chemotherapy for the cancer patients. The molecular pathogenesis of gallbladder cancer is not known extensively. In the present study we investigated whether the expression of AP endonuclease 1 (APE1) and DNA polymerase β (DNA pol β), key enzymes of BER pathway has any clinical ...

متن کاملHypoxia provokes base excision repair changes and a repair-deficient, mutator phenotype in colorectal cancer cells.
UNLABELLED Regions of acute and chronic hypoxia exist within solid tumors and can lead to increased rates of mutagenesis and/or altered DNA damage and repair protein expression. Base excision repair (BER) is responsible for resolving small, non-helix-distorting lesions from the genome that potentially cause mutations by mispairing or promoting DNA breaks during replication. Germline and somatic...
متن کاملGut Microbiota Imbalance and Base Excision Repair Dynamics in Colon Cancer
Gut microbiota are required for host nutrition, energy balance, and regulating immune homeostasis, however, in some cases, this mutually beneficial relationship becomes twisted (dysbiosis), and the gut flora can incite pathological disorders including colon cancer. Microbial dysbiosis promotes the release of bacterial genotoxins, metabolites, and causes chronic inflammation, which promote oxida...
