Figure 4. Diazoxide-mediated recovery of Ca2+-inhibited ATP synthesis.
A, Dose-dependent effect of diazoxide on restoration of Ca2+-inhibited State 3 respiration in subsarcolemmal (SSM) (triangles) and interfibrillar (IFM) (circles) mitochondria. B, Effect of diazoxide on Ca2+-inhibited State 3 respiration in SSM and IFM preloaded with (0–150 nmol Ca2+/mg protein). C, Bar graphs of diazoxide (100 µM)-mediated recovery of Ca2+-inhibited State 3 respiration in SSM and IFM loaded with 150 (open bars) and 30 nmol Ca2+/mg protein (hatched bars), n = 3. Asterisks signify statistical differences with p<0.05.
