1. Effects of calcium-interacting agents on the calcium-induced stimulation of renin release from kidney cortical slices pretreated with calcium-free medium were examined. 2. The exposure of calcium to the slices pretreated with calcium-free medium enhanced the release of renin, followed by a decreased response in the release. The amount of lactate dehydrogenase released from the slices did not correlate with that of renin. 3. High potassium depolarization significantly potentiated the decreased response of renin release, with no influence on the stimulation of the release by exposure to calcium. 4. The decrease in renin release was attenuated by calcium-interacting agents, such as nifedipine, TMB-8 and W-7, but these agents were without effect on the stimulation of the release by exposure to calcium. 5. Thus, the calcium-calmodulin system apparently is not involved in the increased response of renin release following exposure to calcium.

D010042 Ouabain A cardioactive glycoside consisting of rhamnose and ouabagenin, obtained from the seeds of Strophanthus gratus and other plants of the Apocynaceae; used like DIGITALIS. It is commonly used in cell biological studies as an inhibitor of the NA(+)-K(+)-EXCHANGING ATPASE. Acocantherin,G-Strophanthin,Acolongifloroside K,G Strophanthin
D011863 Radioimmunoassay Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation. Radioimmunoassays

D012083 Renin A highly specific (Leu-Leu) endopeptidase that generates ANGIOTENSIN I from its precursor ANGIOTENSINOGEN, leading to a cascade of reactions which elevate BLOOD PRESSURE and increase sodium retention by the kidney in the RENIN-ANGIOTENSIN SYSTEM. The enzyme was formerly listed as EC 3.4.99.19.

D002118 Calcium A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
