Qinglin Yang's Research
Laboratory Research in Dr. Yang's lab focuses on the molecular mechanisms of cardiac hypertrophy and heart failure using techniques including cardiac specific transgenesis, molecular and cell biology, and cardiac pathophysiology. There are currently two major research programs in his laboratory. The first research area involves the generation and analyses of mouse models of Familial Hypertrophic Cardiomyopathy (FHC).
His lab focuses on studies on the regulatory role of cardiac MyBP-C, which is one of the important myofibril proteins, in determining cardiac contractile function. The second area of research in his lab focuses on exploring molecular mechanisms that underlie cardiac energy balance and cardiac function. Disturbances in the regulation of cardiac energy metabolism are associated with the pathogenesis of both inherited and acquired cardiomyopathies. The peroxisome proliferator-activated receptors (PPARs), members of the nuclear hormone receptor transcription factor superfamily, have been implicated in the regulation of lipid metabolism in various tissues. His lab is studying the regulatory role of PPARd on cardiac energy metabolisms and cardiac contraction to establish links between the PPARd pathway, cardiac energy metabolism, contractile function and cardiomyopathy. Cultured cardiomyocytes, transgenic and gene targeting models are used for these studies. Laboratory Techniques There are four areas of technical strengths in our laboratory:
1) molecular biology including most of the routine DNA, RNA and protein
techniques as well as yeast two hybrid screens; 2) development and characterization
of animal models through transgenic approaches; 3) gene transfer using
recombinant viral vectors; 4) Mouse cardiac physiology analyses in cell,
organ and whole animal levels.
