Investigation of the mechanism of action of ouabain and cyclic AMP of the transport of calcium ions by rat heart mitochondria
The action of ouabain and cyclic AMP on the Ca-accumulating capacity and outflow of Ca2+ ions from loaded rat heart mitochondria was studied by the tetracycline probe method. In the course of the investigations no effect of ouabain on these processes was found. Cyclic AMP did not act on Ca binding by the mitochondrial membrane but it induced rapid liberation of Ca2+ from organelles loaded with these ions.
