Adiposity Reduction by Cucumis melo var. gaettongchamoe Extract in High-Fat Diet-Induced Obese Mice

Abstract

This study investigated the anti-obesity effects of Cucumis melo var. gaettongchamoe (CG) in mice fed a high-fat diet (HFD). The mice received CG water extract (CGWE) treatment for 8 weeks, and changes in body weight and serum lipid levels were analyzed. The HFD + vehicle group showed a significant increase in body weight compared to the control group, while the HFD + CGWE and HFD + positive (orlistat) groups exhibited reduced body weight. Lipid profile analysis revealed lower levels of total cholesterol, triglycerides, high-density lipoprotein, and low-density lipoprotein cholesterol in the HFD + CGWE group compared to the HFD + vehicle group. The HFD + vehicle group had increased abdominal fat weight and fat content, whereas both HFD + CGWE groups showed significant reductions in abdominal fat content and adipocyte size. Additionally, CGWE administration downregulated mRNA expression of key proteins involved in neutral lipid metabolism. CGWE also promoted hepatic lipolysis, reducing lipid droplet accumulation in hepatic tissue and altering neutral lipid metabolism protein expression. Furthermore, CGWE treatment reduced inflammatory mediators and suppressed the activation of the mitogen-activated protein kinase pathway in hepatic tissue. In conclusion, CGWE shows promise as a therapeutic intervention for obesity and associated metabolic dysregulation, including alterations in body weight, serum lipid profiles, adipose tissue accumulation, hepatic lipolysis, and the inflammatory response. CGWE may serve as a potential natural anti-obesity agent.

Anti-Obesity Effect and Signaling Mechanism of Potassium Poly-γ-Glutamate Produced by Bacillus subtilis Chungkookjang in High-Fat Diet-Induced Obese Mice

“…Obesity is recognized as a worldwide epidemic and is linked to a spectrum of health issues, such as type 2 diabetes mellitus, hypertension, dyslipidemia, cardiovascular diseases, gallbladder disease, stroke, myocardial infarction, fatty liver disease, osteoarthritis, gout, mental disorders, and specific types of cancers [ 1 , 2 ]. Obesity is characterized by the conversion of excess energy from increased food intake into triglycerides (TGs) which are subsequently stored in adipose tissue, resulting in weight gain [ 3 ].…”
