[Participation of phospholipase A2 in uncoupling in rat liver mitochondria induced by products of lipid peroxidation]. 1990

V G Gogvadze, and N N Bruetovetskiĭ, and A A Zhukova

Accumulation of lipid peroxidation products induced by cumol hydroperoxide (230 microM) results in the loss of the membrane potential only in calcium-loaded mitochondria. The phospholipase A2 inhibitor, p-bromophenylacylbromide, prevents mitochondrial uncoupling but has no effect on the accumulation of lipid peroxidation products.

D008564	Membrane Potentials	The voltage differences across a membrane. For cellular membranes they are computed by subtracting the voltage measured outside the membrane from the voltage measured inside the membrane. They result from differences of inside versus outside concentration of potassium, sodium, chloride, and other ions across cells' or ORGANELLES membranes. For excitable cells, the resting membrane potentials range between -30 and -100 millivolts. Physical, chemical, or electrical stimuli can make a membrane potential more negative (hyperpolarization), or less negative (depolarization).

D008930	Mitochondria, Liver	Mitochondria in hepatocytes. As in all mitochondria, there are an outer membrane and an inner membrane, together creating two separate mitochondrial compartments: the internal matrix space and a much narrower intermembrane space. In the liver mitochondrion, an estimated 67% of the total mitochondrial proteins is located in the matrix.

D002118	Calcium	A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
