摘要：
The deletion of the gene coding for poly(ADP-ribose) polymerase-1 (PARP1) or its pharmacological inhi-bition protects mice against cerebral ischemia and Parkin-son's disease. In sharp contrast, PARP1 inhibitors are in clinical use for the eradication of vulnerable cancer cells. It appears that excessive PARP1 activation is involved in a specific cell death pathway called parthanatos, while inhi-bition of PARP1 in cancer cells amplifies DNA damage to a lethal level. Hence, PARP1 plays a context-dependent role in cell fate decisions. In addition, it appears that PARP1 plays an ambiguous role in organismal aging.
