Research Abstract

The findings of the present research project include ; 1) in contrast to mesangial cells from normotensive rat, enhanced prostaglandin production and attenuation of Ca signal and contraction when extracellular Cl concentration was decreased were absent in mesangial cells of spontaneously hypertensive rat (SHR) and Dahl salt sensitive hypertensive rat (DS) ; 2) normal mesangial cell Ca signal and contraction was attenuated by insulin like growth factor (IGF)-I receptor activation ; 3) modulation of mesangial cell Ca signal and contraction by IGF-I was absent in SHR mesangial cells but present in DS mesangial cells ; 4) IGF-I infusion had no effect on GFR in SHR while it increased GFR in normotensive control rat ; 5) Na/H exchanger-I was present only on the basolateral side of LLCPK-1 cells ; 6) analysis of beta1 receptor mRNA expression revealed its expression in distal tubule ; and 7) Cl conductance was present on the basolateral side of rabbit proximal tubule.
Furthermore, we advanced our hypothesis that disturbance of mesangial cell regulation in this research project underlies the development of hypertension via altered glomerular hemodynamics including disturbed tubuloglomerular feedback.
