PARP-1 inhibition and gene disruption protected against mitochondrial complex I injury and improved myocardial energetics, contractility, and tissue viability in reperfused mouse hearts.
PARP-1 hyperactivity is strongly associated with mitochondrial complex I dysfunction during cardiac ischemia-reperfusion, and its inhibition protects myocardial function and energetics.

Hypothesis-generating in mouse reperfusion injury; human trials needed before clinical consideration.
Zhou et al. (2006) studied Ischemia-reperfusion injury. PARP-1 inhibition or gene disruption vs. Control/wild-type hearts was evaluated on Mitochondrial complex I injury, myocardial energetics, contractility, and tissue viability. PARP-1 inhibition and gene disruption protected against mitochondrial complex I injury and improved myocardial energetics, contractility, and tissue viability in reperfused mouse hearts.
