Anti-hypertrophic effects of oxytocin in rat ventricular myocytes
BACKGROUND: Oxytocin (OT) and functional OT receptor (OTR) are expressed in the heart and are involved in blood pressure regulation and cardioprotection. Cardiac OTR signaling is associated with atrial natriuretic peptide (ANP) and nitric oxide (NO) release. During the synthesis of OT, its precursor, termed OT-Gly-Lys-Arg (OT-GKR), is accumulated in the developing rat heart. Consequently, we hypothesized that an OT-related mechanism of ANP controls
