Methanol extract and fraction of Anchomanes difformis root tuber modulate liver mitochondrial membrane permeability transition pore opening in rats
Objective: Extracts of Anchomanes difformis (AD) are used in folkloric medicine to treat several diseases and infections. However, their roles in mitochondrial permeability transition pore opening are not known. Material and Methods: The viability of mitochondria isolated from Wistar rat liver used in this experiment, was assessed by monitoring their swel...
متن کاملPermeability of rat liver microsomal membrane to glucose 6-phosphate.
Light-scattering measurements of osmotically induced changes in the size of rat liver microsomal vesicles pre-equilibrated in a low-osmolality buffer revealed the following. (1) The increase in extravesicular osmolality by addition of glucose 6-phosphate or mannose 6-phosphate (25 mM each) caused a rapid shrinking of microsomal vesicles. After shrinkage, a rapid swelling phase (t1/2 approx. 22 ...

Physiol. 277 (Cell Physiol. 46): C545–C553, 1999.—Corneal endothelial function is dependent on HCO3 2 transport. However, the relative HCO3 2 permeabilities of the apical and basolateral membranes are unknown. Using changes in intr...
متن کاملMitochondrial Permeability Transition in Rat
42 Onset of the mitochondrial permeability transition (MPT) is the penultimate event 43 leading to lethal cellular ischemia/reperfusion injury, but the mechanisms precipitating 44 the MPT after reperfusion remain unclear. Here, we investigated the role of 45 mitochondrial free Ca and reactive oxygen species (ROS) in pHand MPT-dependent 46 reperfusion injury to hepatocytes. Cultured rat hepatocy...
متن کاملInhibition of the mitochondrial permeability transition by protein kinase A in rat liver mitochondria and hepatocytes.
NO and cGMP administered at reperfusion after ischaemia prevent injury to hepatocytes mediated by the MPT (mitochondrial permeability transition). To characterize further the mechanism of protection, the ability of hepatic cytosol in combination with cyclic nucleotides to delay onset of the calcium-induced MPT was evaluated in isolated rat liver mitochondria. Liver cytosol plus cGMP or cAMP dos...
