title: NADP redox state and mitochondrial Ca2+ efflux: a controversial issue.
abstract: It has been shown that Ca2+ efflux from respiring liver mitochondria is promoted by the oxidized steady state of mitochondrial pyridine nucleotides (NAD(P)), whereas Ca2+ retention is favored by a more reduced state (Lehninger, A.L., Vercesi, A.E. and Bababunmi, E.A., Proceedings of the National Academy of Sciences USA, 75, 1690-1694, 1978). The physiological relevance and the molecular mechanism responsible for the process are controversial and are discussed here.
