Aim: The present study is aimed to examine olvanil's effect in preadipocyte cell culture and on a murine model of diet-induced obesity. We hypothesized that olvanil by being a capsaicinoid will reduce the differentiation to mature adipocytes and reduce the weight of fat tissue in the studied mice. Methods: To determine the effect of olvanil on adipogenesis, 3T3-L1 cells were cultured. Oil red staining was performed to determine lipid accumulation, whereas triglycerides were measured by biochemical determination. Expression of PPAR-γ and PREF-1 were measured by RT-PCR. Therefore, male C57BL/6J mice (CICUAL:2018-020B) were fed with a high-fat diet for 12 weeks to develop a murine model of diet-induced obesity (DIO). Animals were separated into 6 experimental groups: control (standard diet), DIO (high-fat diet), DIO + orlistat (10 mg/kg), DIO + olvanil (10 mg/kg), DIO + olvanil (25 mg/kg) and DIO + olvanil (50 mg/kg), olvanil was administered for 4 weeks. Results: Olvanil inhibits adipogenesis, reduces lipid accumulation and triglycerides in 3T3-L1 adipocytes. PPAR-ɣ gene expression was suppressed while PREF-1 was increased in adipocytes treated with olvanil. Whereas protein expression of FABP4 and PPAR-ɣ decreases significantly with olvanil. The results suggest that olvanil can inhibit the differentiation of preadipocytes to adipocytes through the overexpression or maintenance of PREF-1 levels and the suppression of PPAR-ɣ, and FABP4. Therefore, in diet-induced obesity in mice, olvanil decreases fat accumulation in the body and improve lipid profile by decreasing LDL, VLDL and triglycerides in serum. Conclusion: Olvanil inhibits adipocyte differentiation in 3T3-L1 cells and reduces fat accumulation and ameliorate lipid profile in diet-induced obese mice.
