Summary of academic interest:

Dr. Qin is an Associate Professor in the Whitaker Cardiovascular Institute and the Cardiovascular Medicine Section. He is the Director of the Physiological Core Laboratory in the Myocardial Biology Unit / Cardiovascular Medicine Section. He is also the Manager of the Echocardiography Core in the Whitaker Cardiovascular Institute. Dr. Qin’s laboratory is interested in the role of reactive oxygen species in myocardial remodeling and dysfunction in heart failure. 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. In addition, they are investigating the effects of the polyphenol S17384 or resveratrol on diastolic dysfunction in mice fed high fat and high sucrose. They assess left ventricular structure and function using conventional echocardiography, high-resolution mitral inflow and tissue Doppler echocardiography, maximal exercise test (rodent treadmill), Miller catheter and isovolumic Langendorff heart perfusion techniques. They also assess oxidative stress, myocyte apoptosis, myocyte hypertrophy and myocardial fibrosis. Another major focus in his laboratory is to study the role of oxidative posttranslational modifications of sarcoplasmic reticulum Ca2+ ATPase (SERCA2) in mediating contractile dysfunction in cardiomyocytes isolated from failing mouse hearts. They assess myocyte function and intracellular calcium transients using a video-assisted edge detection system (IonOptix) and oxidative modifications of calcium handling proteins. Their research may provide novel evidence that excessive reactive oxygen species cause oxidative posttranslational modifications of SERCA2 or other calcium handling proteins, leading to myocyte dysfunction in heart failure. Targeting specific protein oxidative posttranslational modifications may lead to novel therapeutic strategies for heart failure.
