Abstract: Growing evidence suggest that, in the heart, sphingosine participates to contractile dysfunction by altering calcium transients and mitochondria function. However, mechanisms underlying sphingosine-induced cardiac mitochondria dysfunction are poorly understood. Here, we studied the effects of sphingosine on isolated cardiac mitochondria of either wild-type or Bcl-2 overexpressing transgenic mice. Sphingosine induced reductions in ADP-coupled respiration, membrane potential, mitochondrial cytochrome c content and ATP production, which were partially prevented by cyclosporine A and mitochondrial Bcl-2 overexpression. These data suggest that sphingosine promotes mitochondrial permeability transition pore opening, which may result in uncoupled respiration and participate in cardiac contractile dysfunction. • Keywords: Sphingosine, Heart, Mitochondria, Cyclosporine, Bcl-2
