WebThe work examines the kinetic parameters of Ca2+ uptake via the mitochondrial calcium uniporter complex (MCUC) and the opening of the Ca2+-dependent permeability transition pore (MPT pore) in the liver and heart mitochondria of rats with high resistance (HR) and low resistance (LR) to acute hypoxia. We found that the rate of Ca2+ uptake by mitochondria …
WebThe mitochondrial permeability transition pore (mPTP) is a protein found in the inner mitochondrial membrane under certain pathological situations. For example, when the mPTP opens, an increase in permeability to molecules less than 1500 Da (MW) is possible.
