The phenomenon of the dual reciprocal regulation of succinate dependent 2H+/Ca2+ exchange was studied in heart and liver mitochondria of experimental animals (allogenic heart transplantation in rat; myocardium infarction in rabbits; pulmonary arteria coarctation in dogs) and in liver bioptates from patients with stomach ulcer. Under pathology two coupled but opposite changes (simultaneous activation and inhibition) in succinate dependent Ca2+ transport occur. The inhibition of Ca2+ transport was detected by its elimination with glutamate, being mostly pronounced after cycle of ADP phosphorylation added to suspension of mitochondria. The treatment of animal with 2-oxoglutarate abolished this inhibition. This was not observed in healthy animals. The described phenomenon can prevent hyperactivation of succinate oxidation under strong pathological (distress) influences.
