Glucose and Its Metabolites Have Distinct Effects on the Calcium-Induced Mitochondrial Permeability Transition
Popis výsledku v původním jazyce
Mitochondrial production of reactive oxygen species (ROS) due to up-regulated glucose oxidation is thought to play a crucial, unifying role in the pathogenesis of chronic complications associated with diabetes mellitus. Mitochondrial permeability transition (MPT) is an interesting phenomenon involved in calcium signalling and cell death. We investigated the effects of glucose and several of its metabolites on calcium-induced MPT (measured as mitochondrial swelling) in isolated rat liver mitochondria. The presence of glucose, glucose 1-phosphate (both at 30 mM) or methylglyoxal (6 mM) significantly slowed calcium-induced mitochondria! swelling. Thirty mM glucose also resulted in a significant delay of MPT onset. In contrast, 30 mM fructose 6-phosphate accelerated swelling, whereas glucose 6-phosphate did not influence the MPT. The calcium binding potentials of the three hexose phosphates were tested and found similar. in vitro hydrogen peroxide production by mitochondria respiring on su
