Dr. Qin is a Professor of Cardiovascular Medicine at the Chobanian and Avedisian School of Medicine. He is the Director of the Physiological Core Laboratory in the Myocardial Biology Unit / Cardiovascular Medicine Section. He is also the Director of the Echocardiography Core in the Whitaker Cardiovascular Institute. Dr. Qin’s research has focused on the cellular and molecular mechanisms of myocardial remodeling and pathophysiology of heart failure, and in particular, the role of reactive oxygen species. They are investigating the effects of catalase overexpression or pharmacological intervention on left ventricular remodeling and dysfunction in transgenic mouse models of heart failure induced by G(alpha)q overexpression as well as mouse models of human heart failure induced by chronic pressure overload or myocardial infarction and diet-induced metabolic heart disease. Dr. Qin has expertise (scientific) in a) oxidative stress, myocyte apoptosis, and apoptosis-related signal transduction pathways, b) oxidative stress, oxidative protein modifications of SERCA2, intracellular calcium transients and myocyte contractile function, c) oxidative stress, myocyte hypertrophy and myocardial diastolic dysfunction. He also has expertise (technical) in the animal models (mice, rats, rabbits and dogs) of myocardial ischemia / reperfusion, coronary artery ligation-induced myocardial infarction and failure, and ascending aortic constriction-induced myocardial hypertrophy and failure, conventional echocardiography, mitral inflow and tissue Doppler echocardiography, in vivo hemodynamics, ex vivo Langendorff isolated heart perfusion, measurements of intracellular calcium concentration and contractile function in isolated myocytes, myocyte culture, histological measurements and biochemical measurements.
