Poly (ADP-ribose) polymerase-1 (PARP1) is an abundant, ubiquitously expressed NAD(+)-dependent nuclear enzyme that has prognostic value for a multitude of human cancers. PARP1 activity serves to poly (ADP-ribose)-ylate the vast majority of known client proteins and affects a number of cellular and biologic outcomes, by mediating the DNA damage response (DDR), base-excision repair (BER), and DNA strand break (DSB) pathways. PARP1 is also critically important for the maintenance of genomic integrity, as well as chromatin dynamics and transcriptional regulation. Evidence also indicates that PARP-directed therapeutics are synthetic lethal in BRCA1/2-deficient model systems. Strikingly, recent studies have unearthed exciting new transcriptional-regulatory roles for PARP1, which has profound implications for human malignancies and will be reviewed herein. (C) 2014 AACR.
