ABSTRACT
Background: Inhibition of adipogenesis has been a therapeutic target for reducing obesity and obesity‑related disorders such as diabetes, hypertension, atherosclerosis, and cancer. For decades, anti‑adipogenic potential of many herbal extracts has been investigated. One example is Garcinia cambogia extract (GE) containing (‑)‑hydroxycitric acid as an active ingredient. GE is currently marketed as a weight loss supplement, used alone or with other ingredients. Pear pomace extract (PE), another natural product, has been also shown to have anti‑adipogenic activity in a recent report. Objective: It was tested if the mixture of PE and GE (MIX) would produce more effective anti‑adipogenic activity than PE or GE alone. Materials and Methods: Differentiation of 3T3‑L1 preadipocyte was induced by adding insulin, dexamethasone, and isobutylmethylxanthine and lipid accumulation was measured by Oil Red O staining. Cellular markers for adipogenesis and lipolysis such as CCAAT/enhancer binding protein (C/EBP‑α), peroxisome proliferator‑activated receptor gamma (PPAR‑γ), fatty acid synthase (FAS), and hormone‑sensitive lipase (HSL) was measured using immunocytochemistry. Results: MIX, compared to PE or GE alone, showed greater inhibition of lipid accumulation. Furthermore, MIX reduced the expression of adipogenesis‑related factors C/EBP‑α, PPAR‑γ, and FAS more than PE or GE alone did. In contrast, the expression of HSL the enzyme required for lipolysis was further enhanced in MIX‑treated adipocytes compared to the PE or GE alone treated groups. Conclusions: Anti‑adipogenic effect of PE and GE appears synergistic, and the MIX may be a useful therapeutic combination for the treatment of obesity and obesity‑related diseases.
