Clinical/Translational Research H2O2-Induced Dilation in Human Coronary Arterioles: Role of Protein Kinase G Dimerization and Large-Conductance Ca -Activated K Channel Activation


Rationale: Hydrogen peroxide (H2O2) serves as a key endothelium-derived hyperpolarizing factor mediating flowinduced dilation in human coronary arterioles (HCAs). The precise mechanisms by which H2O2 elicits smooth muscle hyperpolarization are not well understood. An important mode of action of H2O2 involves the oxidation of cysteine residues in its target… (More)
