The renin-angiotensin system (RAS) is involved in the development of left ventricular hypertrophy (LVH) by which increases cardiac morbidity and mortality. Activation of mitogen-activated protein kinases (MAPKs) and oxidative stress are important in RAS-mediated cardiac hypertrophy. Sesame oil, a potent antioxidant, attenuates hypertension-dependent LVH. We examined the protective role of sesame oil on RAS-mediated MAPK activation and oxidative stress in rats. We induced LVH using a hypertensive model by subcutaneously injecting deoxycorticosterone acetate (DOCA; 15 mg/ml/kg in mineral oil; twice weekly for 5 weeks) and supplementing with 1% sodium chloride drinking water (DOCA/salt) to uninephrectomized rats. Sesame oil was gavaged (0.5 or 1 ml/kg/day for 7 days) after 4 weeks of DOCA/salt treatment. Cardiac histopathology, RAS parameters, expression of MAPKs, reactive oxygen species and lipid peroxidation were assessed 24 h after the last dose of sesame oil. Sesame oil significantly decreased the size of cardiomyocytes and the levels of cardiac renin, angiotensin-converting enzyme and angiotensin II. In addition, sesame oil down-regulated the expression of angiotensin type 1 receptor, JNK and p38 MAPK and apoptosis signal regulating kinase 1, c-Fos and c-Jun in rats receiving DOCA/salt. Furthermore, the induction of nicotinamide adenine dinucleotide phosphate oxidase, superoxide anion and hydroxyl radical and lipid peroxidation by DOCA/salt were inhibited by sesame oil. Sesame oil modulates cardiac RAS to ameliorate LVH by inhibiting MAPK activation and lowering oxidative stress.
