Research
Ongoing research projects related to diabetes obesity
Angiotensin-II (Ang-II) exerts its profound cardiovascular and volume homeostatic properties through activation of specific receptors, primarily Ang-II type 1 (AT1), located both in the periphery (e.g. vasculature and pancreas) and in the brain. Evidence has shown the importance of the brain renin-angiotensin system in the development of hypertension and the pancreatic renin-angiotensin system in type 2 diabetes. Although, new genetic and pharmacological tools have improved our understanding of the global functioning of these systems, the role of individual components and their interactions remain poorly understood due to the difficulty in experimentally dissecting them from the whole organism. Recently, a new element of the RAS, named ACE2, has been identified and is believed to degrade Ang-II to angiotensin-1-7 (Ang1-7), which has great potential for treatment of hypertension and diabetes. Previously, we identified the presence of ACE2 in the brain and pancreas. Our interests focus on the role of this enzyme in modulating the activity of the local renin-angiotensin systems during the development of neurogenic hypertension and type 2 diabetes. Using non-transgenic and genetically-engineered mice in combination with molecular, physiological, and pharmacological tools, our laboratory is dedicated in assessing the relative physiological significance of ACE2 in normal and pathophysiological regulation of blood pressure and glucose homeostasis.
Ongoing projects include
- Role of ACE2 shedding in neurogenic hypertension and diabetes.
- Therapeutic significance of secreted ACE2 in health and disease.
- Characterization of transcription factors involved in the regulation of ACE2 expression in hypertension and diabetes.
- Role of ACE2 in pancreatic beta-cell function and insulin secretion during the development of type 2 diabetes
- Genetic modeling to assess the therapeutic role of sartans in traumatic brain injury.
