Hemal Patel Research Lab

My current and future research interests aim to:

  • Utilize molecular, cellular, and whole animal approaches to understand physiology/pathophysiology in different organ systems
  • My laboratory utilizes cellular models, such as isolated adult rat and mouse cardiac myocytes and neurons, to understand the cellular and sub-cellular consequences of various pathophysiologies
  • These isolated cell systems are more amenable to biochemical and molecular interventions to understand in more sophisticated detail the mechanisms that are at play in disease and can be exploited to elicit protective responses
  • I use translational models (i.e., transgenic and knockout mice, an intact and ex vivo rat model of ischemia-reperfusion injury, and in vivo pharmacologic studies) to bridge the in vitro biochemical and molecular outcomes to a better understanding of whole organ and animal function
  • I am interested in how cellular signaling is organized and coordinated in cells and how this is impacted
    by various disease processes
  • My laboratory is specifically interested in how membrane microdomains, such as caveolae, interact and communicate with intracellular organelles, such as mitochondria, to impact cell, organ, and animal physiology
  • I hope that this multi level approach to the study of disease will lead to fundamental discoveries related to heart disease, stroke, diabetes, cancer and aging
