The sustained opening of the mitochondrial permeability transition pore (PTP) is a decisive event in the onset of irreversible cell injury. The PTP is modulated by numerous exogenous and endogenous effectors, including mitochondrial membrane potential, ions and metabolites. Mitochondrial sirtuins have recently emerged as pivotal mediators of mitochondrial metabolism. In the present study, we demonstrate that sirt-4 modulates sensitivity to PTP onset induced by calcium and the oxidative cross linking reagent phenylarsine oxide, and PTP dependent cytotoxicity brought about by TNF or doxorubicin. Moreover, the ability of sirt-4 to modulate onset of the PTP is dependent on the expression of glutamate dehydrogenase-1.
