Understanding the impact of the p53 tumor suppressor pathway on the regulation of genome integrity, cancer development, and cancer treatment has intrigued scientists and clinicians for decades. It appears that the p53 pathway is a central node for nearly all cell stress responses, including: gene expression, DNA repair, cell cycle arrest, metabolic adjustments, apoptosis, and senescence. In the past decade, it has become increasingly clear that p53 function is directly regulated by poly(ADP-ribose) polymerase-1 (PARP-1), a nuclear enzyme involved in DNA repair signaling. Here, we will discuss the impact of PARP-1 on p53 function, along with a recently described novel role for the reciprocal regulation of p53 regulated, PARP-1 dependent necrosis following DNA damage.
