Parthanatic
WebParthanatos is a form of nonapoptotic cell death driven by the hyperactivation of a specific PARP-1’s component, involving generation of ROS, increase in mitochondrial permeability, … WebPARP1 hyper-activation is the first and critical step in the parthanatic cascade. The inhibition or deficiency of PARP1 is protective in models of the cell and rat/mouse injury paradigms, including retinal degeneration diseases, stroke, diabetes, I/R injury, neurodegenerative disease, and heart failure .

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]. In our previous study, we have confirmed that MNNG is able to induce AIF
