Comparative metabonomics of Wenxin Keli and Verapamil reveals differential roles of gluconeogenesis and fatty acid β-oxidation in myocardial injury protection.

Abstract:

:Metabonomics/metabolomics is a rapid technology for comprehensive profiling of small molecule metabolites in cells, tissues, or whole organisms, the application of which has led to understanding pathophysiologic mechanisms of cardiometabolic diseases, defining predictive biomarkers for those diseases, and also assessing the efficacious effects of incident drugs. In this study, proton nuclear magnetic resonance (NMR)-based metabonomics was employed to identify the metabolic changes in rat plasma caused by myocardial ischemia-reperfusion injury (MIRI), and to compare the metabolic regulatory differences between traditional Chinese medicine Wenxin Keli (WXKL) and Western medicine verapamil. The results revealed that energy-substrate metabolism were significantly disturbed by ischemia-reperfusion (I/R) in myocardium and bulk of the key metabolites could be further modulated by verapamil and/or WXKL. Lipid metabolism and amino acid transamination occurred mainly following the treatment of verapamil, whereas glucose oxidation and BCAA degradation were prominently ameliorated by WXKL to content the energy demands of heart. Moreover, both WXKL and verapamil improved the secretions of taurine and ketone bodies to overcome the oxidative stress and the shortage of energy sources induced by ischemia-reperfusion.
