PARP interacts with, and is recruited to, DNA damage sites along with epigenetic factors, such as DNA methyltransferase 1 (DNMT1). In addition to increasing PARP-trapping, inhibitors of DNMT modulate ROS-cAMP/PKA signaling and induce a pathogen mimicry, inflammasome signaling response and a BRCAness phenotype t...
