Sakthivel Sadayappan , MBA

The long-term goal of the Sadayappan Lab involves 1) elucidating the causes of muscle-specific diseases at the molecular level and 2) identifying therapeutic targets that will lead to the development of effective cures. The more specific objectives involve determining the up- and downstream regulators of sarcomere structure and function of both cardiac and skeletal muscles in health and disease. The sarcomere is the functional unit of striated muscle to generate contractility. Accordingly, the Sadayappan Lab has consistently focused on improving cardiac sarcomere function during ischemia-reperfusion injury. We have learned that sarcomere proteins undergo severe proteolytic damage during ischemia-reperfusion injury, resulting decreased contractile force and cardiac function. Therefore, the short-term goals of current research studies involve 1) identifying cardiac-specific early biomarkers of HF (NIH-NHLBI K02HL114749), 2) restoring sarcomere structure and function (NIH-NHLBI R01HL105826), and 3) screening for compounds to improve sarcomere function during ischemia-reperfusion injury. In particular, hypertrophic cardiomyopathy (HCM) is a major genetic disorder among populations of South Asian descent, leading to contractile dysfunction, heart failure, and sudden cardiac death. Therefore, we are also engaged in determining the pathophysiological mechanism of the South Asian-specific MYBPC3 gene variant that has been associated with the development of HCM. Using various mouse models and in vitro culture systems expressing the MYBPC3 gene variant, we aim to unravel the molecular mechanisms associated this mutant (NIH-NHLBI R01HL130356). To carry out this study, we are performing genome-phenome analysis in South Asians who carry the MYBPC3 gene variant and who live in the USA (AHA 15CVGPSD27020012). Finally, in an unrelated, but nonetheless pivotal, study, we are studying the differential role(s) of slow and fast myosin binding protein-C in skeletal muscles (R01AR067279, PI: Craig and Warshaw), using both in vitro culture systems and animal models. As part of our commitment to the development of young scientists, the Sadayappan Lab provides expertise and training in cell biology, molecular biology, structural biology and physiology of the muscle and encourages collaborations in various areas of muscle biology.
