Complementation of aprataxin deficiency by base excision repair enzymes in mitochondrial extracts
Mitochondrial aprataxin (APTX) protects the mitochondrial genome from the consequence of ligase failure by removing the abortive ligation product, i.e. the 5'-adenylate (5'-AMP) group, during DNA replication and repair. In the absence of APTX activity, blocked base excision repair (BER) intermediates containing the 5'-AMP or 5'-adenylated-deoxyribose phosphate (5'-AMP-dRP) lesions may accumulat...
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 کاملRepair activity of base and nucleotide excision repair enzymes for guanine lesions induced by nitrosative stress
Nitric oxide (NO) induces deamination of guanine, yielding xanthine and oxanine (Oxa). Furthermore, Oxa reacts with polyamines and DNA binding proteins to form cross-link adducts. Thus, it is of interest how these lesions are processed by DNA repair enzymes in view of the genotoxic mechanism of NO. In the present study, we have examined the repair capacity for Oxa and Oxa-spermine cross-link ad...
متن کاملTranscriptional regulation of the base excision repair pathway by BRCA1.
Inactivation of the breast cancer susceptibility gene BRCA1 plays a significant role in the development of a subset of breast cancers, although the major tumor suppressor function of this gene remains unclear. Previously, we showed that BRCA1 induces antioxidant-response gene expression and protects cells against oxidative stress. We now report that BRCA1 stimulates the base excision repair pat...
متن کاملPredictive value of excision repair cross-complementing rodent repair deficiency complementation group 1 and ovarian cancer risk.
OBJECTIVE We aimed to analyze the association between excision repair cross-complementing rodent repair deficiency complementation group 1 (XRCC1) and ovarian cancer risk. METHODS We performed a hospital-based case-control study with 155 cases and 313 controls in China. All Chinese cases with newly diagnosed primary ovarian cancer between May 2005 to May 2010 in our hospital were invited to p...
