Effect of ANT-deficiency on mtPTP activation in liver mitochondria. a, ANT-control and b, ANT-deficient mtPTP activation by ΔP depolarization (FCCP) monitored by mitochondrial swelling. Black trace, no CsA; red trace, with CsA. c, Amount of Ca2+ required per mg of mitochondrial protein to activate the mtPTP and collapse ΔP. d, Western blots of cytochrome c released into the supernatant fraction versus COI retained in the mitochondrial pellet following Ca2+-activation of the mtPTP. e, ANT-control and f, ANT-deficient Ca2+-activation of the mtPTP in the presence of positive and negative effectors.
