Abstract:
:The effects of Bay K 8644 [methyl-1,4-dihydro-2,6-dimethyl-3-nitro-4-(2-trifluoromethylphenyl) -pyridine-5-carboxylate], a calcium channel agonist, on renin release in rat kidney cortical slices were examined. Bay K 8644 produced a dose-related inhibition of renin release in the presence of 15 mM potassium. The inhibitory effect of Bay K 8644 on this release was abolished when calcium was excluded from the incubation medium. Nifedipine exerted a concentration-dependent blocking action on the inhibition of renin release by Bay K 8644. These findings support the proposal that calcium influx into the renin secretory cells is an inhibitory signal for renin release.
