Abstract:
... Oxidative stress-induced DNA damage in cells activates Poly ADP Ribose Polymerase 1 (PARP1) as a part of the repair process. Since it is an energy-dependent process, overactivation of PARP1 results in energy depletion and as a consequence causes parthanatos – a subtype of necrosis. Beneficial effects of inhibiting PARP1 using chemicals such as 3-aminobenzamide (3-AB) has been well documented and w ...
