Research Title/Research Topic: Identifying Molecular Mechanisms within Preglomerular Vascular Smooth Muscle Cells that Contribute to Enhanced Renal Vascular Resistance in Spontaneously Hypertensive Rats
Current Research Description: Development of essential hypertension is intimately related to impaired renal hemodynamics, yet molecular mechanisms governing this phenomenon are poorly understood. We hypothesize that enhanced contraction by preglomerular vascular smooth muscle cells may be responsible for elevating renal vascular resistance in spontaneously hypertensive rats, due to greater membrane localization of contractile signal transducers.
