Sodium ferulate (SF) is the sodium salt of ferulic acid which is an active ingredient of Radix Angelica Sinensis and Ligusticum chuanxiong hort. Here, we investigated SF inhibition in a rat model of myocardial hypertrophy induced by coarctation of the abdominal aorta. Following coarctation, rats were given SF (20, 40, and 80 mg/kg/day) for 25 consecutive days. We characterized myocardial hypertrophy using myocardial hypertrophic parameters, histopathology, and gene expression of atrial natriuretic factor (ANF). a gene related to myocardial hypertrophy. We detected the levels of angiotensin II (Ang II) and endothelin-1 (ET-1), protein kinase C beta (PKC-beta), Raf-1, extracellular regulated protein kinase 1/2 (ERK1/2), and mitogen-activated protein kinase phosphatase-1 (MKP-1) in myocardium. Notably, coarctation of the abdominal aorta increases myocardial hypertrophic parameters, cardiac myocyte diameter, the concentration of Ang II and ET-1 in myocardium, and gene expression of ANF. SF significantly ameliorates myocardial hypertrophy caused by coarctation of the abdominal aorta; reduces concentrations of Ang II and ET-1; suppresses the overexpression of ANF, PKC-beta, Raf-1, and ERK1/2; and increases the expression of MKP-1. These results indicate that SF alleviates myocardial hypertrophy induced by coarctation of the abdominal aorta, and these protective effects could be related to the inhibition of PKC and mitogen-activated protein kinase (MAPK) signaling pathways.
