Calcium dependence of phenylephrine-, endothelin-, and potassium chloride-stimulated atrial natriuretic factor secretion from long term primary neonatal rat atrial cardiocytes.

Since calcium is involved in both excitation-secretion and excitation-contraction coupling, it was of interest to evaluate its involvement in atrial natriuretic factor (ANF) release from atrial cardiocytes. In medium containing physiological levels …

The secretion of atrial natriuretic factor-(99-126) by cultured cardiac myocytes is regulated by glucocorticoids.

Atrial natriuretic factor (ANF) is stored in mammalian atria primarily as ANF-(1-126), the precursor to the known circulating form of the hormone ANF-(99-126). When primary cultures of atrial myocytes were maintained in a complete serum-free medium, …
