Phosphate transport in rat-liver mitochondria.
Vesicles have been prepared by mild sonication of a purified inner membrane fraction from rat liver mitochondria. Such vesicles demonstrate an energy-dependent net concentrative uptake of inorganic phosphate in the absence of added Na+, Ca’+, or ionophores. Phosphate uptake can be supported by a variety of substrates including /?-hydroxybutyrate, succinate, and ascorbate + tetramethylphenylened...
متن کاملA kinetic study of sulphate transport in rat liver mitochondria.
The kinetics of sulphate uptake catalysed by the dicarboxylate carrier were measured. The Km value for sulphate is about 0.3 mM. A completely competitive relation exists between the influxes of sulphate and malonate, whereas the relation between sulphate and phosphate is of the mixed type. The inhibition of sulphate influx by mersalyl and bathophenanthroline is similar to that of malonate influ...
متن کاملThe Effect of Resveratrol against Acrolein Toxicity in Mitochondria isolated from Rat Liver
Introduction: Acrolein is an important environmental, food and water pollutant that plays an important role in the development of several diseases. Resveratrol is a phenolic compound with antioxidant properties found in fruits such as grapes, berries and peanuts. The purpose of this study was to evaluate the protective effect of resveratrol in preventing Acrolein-induced toxicity in isolated mi...
متن کاملMonocarboxylic acid transport.
Monocarboxylates such as lactate, pyruvate, and the ketone bodies play major roles in metabolism and must be transported across both the plasma membrane and mitochondrial inner membrane. A family of five proton-linked MonoCarboxylate Transporters (MCTs) is involved in the former and the mitochondrial pyruvate carrier (MPC) mediates the latter. In the intestine and kidney, two Sodium-coupled Mon...
متن کاملStudy of the Effects of ATP Suppliers and Thiol Reductants on Toxicity of Pioglitazone in Isolated Rat Liver Mitochondria
Pioglitazone (PG) is one of thiazolidinediones used for the treatment of type II diabetes mellitus. Some reports of its hepatotoxicity exist, but the mechanism of its hepatotoxicity is not well known. In the present study, the protective effect of some ATP suppliers are investigated against mitochondrial toxicity of PG in isolated rat mitochondria. Mitochondrial viability was investigated by MT...
