Web12 Jan 2024 · Poly(ADP-ribose) polymerase 1 (PARP1) is well known as an ADP-ribosylating enzyme involved in a number of cellular processes, including DNA repair, genomic … As NAT10 regulates cellular sensitivity to DNA-damaging agents [16], we proceeded to determine the effects of NAT10 PARylation on the sensitivity of MCF-7 and BT549 cells to MMS and IR. Briefly, we reintroduced the empty vector pCDH, HA-NAT10 WT, and HA-NAT10 K3A into NAT10-KO MCF-7 and BT549 cells, and … See more PARP1-mediated PARylation is well known to mediate the first wave of cellular response to DNA damage generated either exogenously or endogenously [25]. To … See more To map the PARylation sites of NAT10 by PARP1, we carried out in vitro PARylation assays using a series of GST-NAT10 deletion constructs. Of note, PARylation of … See more ford explorer rollover lawsuit
