Involvement of cytoplasmic calcium and protein kinases in the regulation of atrial natriuretic factor secretion by contraction rate and endothelin.

To characterize the effects of the cellular events associated with contraction on atrial natriuretic factor (ANF) secretion, primary neonatal rat atrial myocytes were electrically paced to contract while being monitored for ANF release, cytoplasmic …

Myocardial alpha-thrombin receptor activation induces hypertrophy and increases atrial natriuretic factor gene expression.

The protease, alpha-thrombin (alpha Th), affects myocardial cell contractility, a feature common among agents that induce hypertrophy. However, it is not known whether cardiac myocytes possess alpha Th receptors (alpha Th-R), or if long term …
