Abstract
Effect of synthetic rat atrial natriuretic peptide (1-28) (ANP) on the cGMP content was studied using defined nephron segments of rat kidney. ANP elevates cGMP contents in glomeruli in a concentration and time-dependent manner. The increase of cGMP was observed in glomeruli, distal convoluted tubule (DCT) and cortical collecting tubule (CCT) (delta %; 279 +/- 35, 148 +/- 10 and 152 +/- 18, respectively), and no effect was observed in proximal convoluted (PCT) and straight tubule (PST). These results suggest that ANP may act directly on the tubular cells as well as glomeruli. In glomeruli, effects of ANP and carbamylcholine on cGMP contents were additive suggesting that these two agents may act on different receptors. Angiotensin II and norepinephrine failed to affect the ANP-induced cGMP production in the glomeruli.Entities:
