Abstract:
ETHNOPHARMACOLOGICAL RELEVANCE:Most cardiovascular diseases ultimately result in heart failure, an intractable problem in modern medicine. Yangxinshi tablet (YXS) is a Chinese medicine formula that is used clinically to treat coronary heart disease. However, the active compounds, potential targets, and pharmacological and molecular mechanism of its anti-heart failure activity remain unclear. Therefore, further investigation is required. AIM OF STUDY:Active ingredients and potential targets of YXS for treating heart failure have been reported previously. However, the molecular functions or biological processes of YXS in energy metabolism have not been discovered. To date, no experimental study to validate the potential anti-heart failure mechanism of YXS. The aim of this study was to study the therapeutic effect of YXS on rats with chronic ischemic heart failure by evaluating rat cardiac function and exercise tolerance, and to explore its potential mechanism by network pharmacology, western blotting, quantitative RT-PCR and histological analysis. MATERIALS AND METHODS:In this investigation, chronic ischemic heart failure rats were randomly assigned to five groups: control group (sham operation), model group (0.5% CMC-Na), trimetazidine group (positive control) and two YXS groups (low- and high-dose groups). Experimental rats were treated by gavage with 10 mg/kg/d (clinical equivalent dose) trimetazidine (TMZ), 500 mg/kg/d (clinical equivalent dose) YXS and 1000 mg/kg/d YXS, respectively, for 5 weeks. The cardiac functions of rats were detected by High-Resolution In Vivo Imaging System. We elucidated novel understanding of the active compounds of YXS in rat plasma and predicted the energy metabolism related targets and processes for heart failure. Then, we validated experimentally the targets and mechanism of YXS on these pathological processes in vivo. RESULTS:It was found that YXS was able to effectively improve cardiac LVIDs, LVEDV, LVESV and EF, decrease myocardial oxygen consumption and reduce myocardial infarct size in rats with chronic ischemic heart failure was similar to that of TMZ. We identified 63 major candidate targets for YXS that are closely to heart failure progression. Enrichment analysis revealed key targets for YXS associated to oxygen delivery, glucose utilization, and mitochondrial biogenesis. Meanwhile, we validated that YXS could promote the expression of downstream HIF-1α, PGC1α and GLUT4 by increasing phosphorylation of PI3K, Akt, mTOR, rpS6 and AMPK. The results show that YXS could activate related PI3K/Akt/mTOR/rpS6/HIF-1α and AMPK/PGC1α/GLUT4 signaling pathways in chronic ischemic heart failure rats. Further experiments demonstrated that YXS increased mitochondrial biogenesis in chronic ischemic heart failure rats and improved exercise tolerance CONCLUSION: YXS treated chronic ischemic heart failure through activating its targets which play pivotal roles in oxygen delivery, glucose utilization and mitochondrial biogenesis to improve energy metabolism through a multi-component, multi-level, multi-target, multi-pathway and multi-mechanism approaches.
