"Myocardial Contraction/drug effects/*physiology"

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 …
