Title: DNA Repair: ERCC1, Nucleotide Excision Repair, and Platinum Resistance
Abstract: DNA excision repair plays a significant part in platinum-based chemotherapy by removing DNA lesions caused by platinum-containing drugs. The nucleotide excision repair (NER) pathway is the mammalian DNA repair mechanism that removes bulky DNA adducts induced by DNA damaging chemotherapeutic agents. Platinum compounds induce their cytotoxic effect by binding to a DNA molecule in the form of a platinum-DNA-adduct. The NER pathway is the main mechanism responsible for platinum resistance by increased platinum-DNA-adduct removal and the excision repair cross complementing-group 1 (ERCC1) gene plays a major role in the NER-pathway because of its damage recognition and excision ability. This chapter will review mechanisms of DNA repair and platinum resistance as it relates to the NER pathway and regulation of ERCC1. A brief discussion on the role of cancer stem cells in platinum resistance is also presented.
