Macrotyloma uniflorum a plant food alleviates the metabolic syndrome through modulation of adipokines and PPARs.

Abstract

A sedentary lifestyle combined with the intake of high-calorie diet has been the paramount cause of metabolic syndrome (MS) which is now a serious concern of public health worldwide as it involves the coexistence of hypertension, hyperlipidemia, glucose intolerance, and obesity. Hence, identifying a suitable strategy to overcome the worldwide menace of MS is imperative. Macrotyloma uniflorum a lesser known legume is highly nutritious and notable for its ethano-medicinal potential. Herein, the influence of M. uniflorum in high-fat dietinduced metabolic changes in a rodent model of metabolic syndrome was evaluated. Serum levels of glucose, total cholesterol, triglycerides, VLDL-c, and bodyweight were decreased, whereas HDL-c was increased in M. uniflorum-treated MS rats. The protein expression (AMPK-α, PPAR-α, and PPAR-γ) and gene expression (leptin, adiponectin, resistin, UCP2, NF-κB, and IL-6) results are impressive to highlight that M. uniflorum modulates the pathological conditions of MS and proves to be cardioprotective. Furthermore, the histopathological analysis confirmed the pathological changes and substantiates the influence of M. uniflorum to overcome MS. The HPLC and GC (MS) profiling reveals the presence of an array of polyphenols such as rutin (694.61μg/g), catechin (500.12μg/g), epicatechin (158.10μg/g), gallic acid (17.98μg/g), ferulic acid (10.911μg/g), daidzein (6.51μg/g), and PUFA, respectively, which probably exhibits the therapeutic effect on MS and associated complications by modulating lipid metabolism and adipogenesis. PRACTICAL APPLICATIONS: Metabolic disorders like CVD and diabetes are leading cause of mortality and morbidity worldwide. With emerging issues on adverse effects of modern drugs, the emphasis on "Food is Medicine and Medicine as Food" has taken dramatic dimensions in the healthcare sector. Therefore, nutraceuticals are in great demand in the developed world off late. Legumes, are potent elements in a balanced diet next to cereals. Exploring the medicinal properties of legumes could bring a revolution in public health and nutraceutical industries. This study scientifically validated the phytochemicals in M. uniflorum for its functional potential in the management of Metabolic Syndrome (MS). This study would help the nutraceutical industries to develop functional foods using M. uniflorum seeds to make porridges and soups or nutraceutical supplements with the bioflavonoids isolated from M. uniflorum for the management of metabolic disorders by mitigating hyperlipidemia, oxidative stress, and inflammation.
