Research Interests:

  • My principal research interest is the physiology of the central and peripheral mechanisms of the regulation of blood pressure and salt sensitivity, and the role of the renal dopaminergic system and the oxidative stress.
  • Essential hypertension affects 25% of the adult population. Approximately 14% of subjects with normal blood pressure and about 40% of subjects with high blood pressure are salt-sensitive.
  • The genetic, molecular, and biochemical mechanisms of salt sensitivity and inverse salt sensitivity are not well understood. Dopamine, produced by the kidney, independent of renal nerves, is important in the regulation of sodium balance, renal function, and blood pressure.
  • There are two familes of dopamine receptors: D1-like (D1R and D5R) and D2-like (D2R, D3R and D4R) receptors, all of which are expressed in the kidney.
  • Impaired renal dopamine production and receptor dysfunction are involved in the pathogenesis of human essential hypertension and rodent models of hypertension.
  • My research efforts have focused on the elucidation of the roles of DJ-1 and PON2 on the D2R expression and function.
  • The genetic ablation of DJ-1, PON2 and D2R results in hypertension in mice.
  • My expertise is on the genetics and physiology of hypertension in cardiovascular disorders.
