Prostaglandins contribute to the regulation of renin synthesis and secretion. We tested the hypothesis that the inducible isoform of prostaglandin G/H synthase, cyclooxygenase-2, contributes to the stimulation of renin synthesis in renovascular hypertension. The expression of cyclooxygenase-2 and renin was investigated in the kidneys of rats with two-kidney, one-clip renovascular hypertension o...
