Web12 Sep 2024 · Parthanatos is presented as death resulting from the execution of a well-choreographed cascade of events, with key distinguishing molecular events described in sequence, including the rapid activation of PARP, synthesis and accumulation of the poly (ADP-ribose) (PAR) polymer and translocation of the apoptosis-inducing factor (AIF) … Web9 Jan 2024 · PARP1, the critical mediator of parthanatos, is known to bind ERG and required for ERG-mediated transcription. Nifuroxazide blocked this interaction, and overly activated PARP1, leading to cell death that was reduced by olaparib, a PARP1 inhibitor. These results show that nifuroxazide inhibits ERG, leading to parthanatic cell death.

This is a PARP (Poly ADP-ribose Polymerase) mediated, well regulated cell death mechanism. It’s proven that its different from APOPTOSIS because there is no Caspase activity as seen in Apoptosis. WebPARP1-dependent parthanatic cell death. Widespread as an environ-mental mutagen, N-methyl-N′-nitro-N-nitrosoguanidine (MNNG) is such a commonly used DNA-alkylating agent that potently initiates parthanatic cell death in a caspase-independent manner [3].
