Research Interests

• The research of our laboratory has been focused on 2 major areas. One is to determine the significance of tubuloglomerular feedback (TGF) response in control of renal hemodynamics, salt-water balance and hypertension under physiological and pathophysiological conditions. TGF response is an intrarenal regulatory process by which increases in NaCl delivery at the macula densa cause constriction of the afferent arterioles, thereby decreasing glomerular filtration rate and NaCl delivery to the distal nephron. Another area is to study the renal mechanisms and identify potential therapeutic targets for kidney injury, including acute kidney injury, chronic kidney disease, diabetic nephropathy and graft dysfunction after kidney transplantations. The techniques used in our laboratory include microperfusion of kidney tubules and arterioles in vitro, micropuncture in vivo, molecular biology, cell biology, mouse and rat kidney transplantation, systemic hemodynamic measurement, and tissue knockout
