Figure 3. Effect of diazoxide on the membrane potential and Ca2+ handling in subsarcolemmal (SSM) and interfibrillar (IFM) mitochondria.

Figure 3

A, Depolarizing effect of diazoxide (100 µM) in SSM (open bar) and IFM (filled bar), n = 6, p<0.05. B, Mitochondrial Ca2+ uptake in SSM and IFM in the absence (-DZ) and presence (+DZ) of diazoxide (100 µM). C, Inhibition of the rate of Ca2+ uptake in SSM (open bar) and IFM (filled bar), n = 6, p<0.05. D, Diazoxide (100 µM) mediated Ca2+ release from preloaded SSM and IFM. E, Average rate of diazoxide-mediated Ca2+ release from mitochondria, n = 3, p<0.05. F and G, Dose-dependent effect of diazoxide on Ca2+ uptake (F) and Ca2+ release (G) in SSM (triangles) and IFM (circles), n = 6.
