Abstract Cancer cells frequently harbor defects in DNA repair pathways, leading to genomic instability. This can foster tumorigenesis but also provides a weakness in the tumor that can be exploited therapeutically. Tumors with compromised ability to repair double-strand DNA breaks by homologous recombination, including those with defects in BRCA1 and BRCA2, are highly sensitive to blockade of the repair of DNA single-strand breaks via the inhibition of the enzyme poly(ADP) ribose polymerase. This provides the basis for a novel synthetic lethal approach to cancer therapy. This article was published in J Clin Oncol and referenced in Journal of Cancer Science & Therapy
