Endogenous ghrelin has been shown to exert a beneficial effect on cardiac dysfunction and postinfarction remodeling via modulation of the autonomic nervous system. However, ghrelin\u2019s ability to attenuate cardiac hypertrophy and its potential mechanism of action are unknown. In this study, cardiac hypertrophy was induced by transverse aortic constriction in ghrelin knockout mice and their wild-type littermates. After 12 weeks, the ghrelin knockout mice showed significantly increased cardiac hypertrophy compared with wild-type mice, as evidenced by their significantly greater heart weight\/tibial length ratios (9.2\u00b11.9 versus 7.9\u00b10.8 mg\/mm), left ventricular anterior wall thickness (1.3\u00b10.2 versus 1.0\u00b10.2 mm), and posterior wall thickness (1.1\u00b10.3 versus 0.9\u00b10.1 mm). Furthermore, compared with wild-type mice, ghrelin knockout mice showed suppression of the cholinergic anti-inflammatory pathway, as indicated by reduced parasympathetic nerve activity and higher plasma interleukin-1\u03b2 and interleukin-6 levels. The administration of either nicotine or ghrelin activated the cholinergic anti-inflammatory pathway and attenuated cardiac hypertrophy in ghrelin knockout mice. In conclusion, our results show that endogenous ghrelin plays a crucial role in the progression of pressure overload\u2013induced cardiac hypertrophy via a mechanism that involves the activation of the cholinergic anti-inflammatory pathway.<\/jats:p>","DOI":"10.1161\/hypertensionaha.114.04864","type":"journal-article","created":{"date-parts":[[2015,4,14]],"date-time":"2015-04-14T02:42:27Z","timestamp":1428979347000},"page":"1238-1244","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":49,"title":["Endogenous Ghrelin Attenuates Pressure Overload\u2013Induced Cardiac Hypertrophy via a Cholinergic Anti-Inflammatory Pathway"],"prefix":"10.1161","volume":"65","author":[{"given":"Yuanjie","family":"Mao","sequence":"first","affiliation":[{"name":"From the Department of Biochemistry, National Cerebral and Cardiovascular Center Research Institute, Suita, Japan (Y.M., T.T., I.K., H.N., M.M., K.K.);
