In the present study, we assessed the therapeutic potential of Biochanin-A (BCA) (10 mg/kg BW/day) pretreatment for 30 days on lipid metabolic abnormalities, proinflammatory cytokines and matrix metalloproteinase expression in isoproterenol (ISO)-induced myocardial infarction (MI) in rats. We measured the potential role of BCA on tissue and circulatory lipid profiles as well as on lipid metabolic enzymes: serum inflammatory cytokines (TNF-α, IL-1α, IL-1β, IL-6 and MCP1) and serum Matrix Metalloproteinases (particularly, MMP-2 and MMP-9) together with mRNA expressions of TNF-α, IL-6, MMP-2 and MMP-9 by RT-PCR analysis. Administration of ISO to rats significantly distorted their lipid metabolism and augmented inflammatory process, MMP expression and proteolytic activity. In addition, pretreatment with BCA of ISO-induced MI rats significantly reestablished the altered lipid metabolism and concealed the inflammation of cytokines. BCA suppressed the expressions of proinflammatory cytokines and MMPs in ISO-induced MI in rats when compared to normal untreated MI rats. Hence, these results established that BCA could improve the pathological processes of myocardial remodeling which was confirmed by histopathology of heart in MI rats and might be an effective beneficial ingredient for the management of heart failure disorders.
