[Inhibition of gluconeogenesis in the kidneys by a cytoplasmic regulator of mitochondrial membrane permeability].

Cytoplasmatic glycoprotein previously shown to be an inhibitor of mitochondrial membrane permeability for oxidation substrates inhibits in-vitro gluconeogenesis from pyruvate, lactate, succinate, alpha-ketoglutarate and glutamate in slices of the renal cortical layer. The inhibition was reduced with Ca2+ concentration increase in the incubation medium from 0.02 to 2 mM.
