The natural compounds genistein (G), quercetin (Q), and resveratrol (R) have been reported to each exhibit anti-adipogenic activities in adipocytes and antiproliferative and pro-apoptotic activities in several cell types. We studied the combined effects of G, Q, and R on adipogenesis and apoptosis in primary human adipocytes (HAs) and 3T3-L1 murine adipocyte (MAs). Combined treatment with 6.25 microM G, 12.5 microM Q, and 12.5 microM R during the 14-day differentiation period caused an enhanced inhibition of lipid accumulation in maturing HAs that was greater than the responses to individual compounds and to the calculated additive response. Glycerol 3-phosphate dehydrogenase activity, a marker of late adipocyte differentiation, was decreased markedly in HAs treated with the combination of G+Q+R. In addition, combined treatment with 50 microM G, 100 microM Q, and 100 microM R for 3 days decreased cell viability and induced apoptosis in early- and mid- phase maturing and lipid-filled mature HAs. In contrast, no compound alone induced apoptosis. Oil Red O stain and Hoechst 33342 stain were performed to confirm the effects on lipid accumulation and apoptosis, respectively. We also determined whether MAs responded to the combination treatment similarly to HAs. As in HAs, G+Q+R treatment decreased lipid accumulation in maturing MAs and increased apoptosis in pre- and lipid-filled mature MAs more than the responses to G, Q, and R when used separately. These results show that lower concentrations of combined treatments with several natural compounds may be useful for treatments for obesity through the suppression of adipogenesis and enhanced adipocyte apoptosis.

    • "In this study, the PSE supplementation (containing 0.05% resveratrol) showed significantly decreased visceral adipose fat weights, even much higher effects than pure 0.05 % resveratrol supplementation reported by previous studies [9,10,11,12]. Two previous in vitro studies reported that combination treatment with resveratrol and genistein or other natural polypherols suppressed lipid accumulation significantly more than the responses to resveratrol alone [25,26]. Those studies suggested that resveratrols's anti-adipogenic activity was substantially enhanced by the other natural isoflavornes or pholypherols compound in foods. "

    ABSTRACT: This study aims to find out the effects of peanut sprout extracts on weight controls and protein expressions of transcription factors related to adipocyte differentiation and adipocytokine in rats under high-fat diets. Four week-old Sparague-Dawley (SD) were assigned to 4 groups; normal-fat (NF) diets (7% fat diet), high-fat (HF) diets (20% fat diet), high fat diets with low peanut sprout extract (HF + PSEL) diet (20% fat and 0.025% peanut sprout extract), and high fat diets with high peanut sprout extract (HF + PSEH) diet (20% fat and 0.05% peanut sprout extract). Body weight changes, lipid profiles in adipose tissue, and the mRNA protein expressions, such as peroxisome proliferator-activated receptor γ (PPARγ), CCAAT element binding protein α (C/EBP α), leptin, and adiponectin, were determined. After 9 weeks of feeding, the HF + PSEH group had significantly less weight gains than the HF group (P < 0.05). However, the total dietary intakes or food efficiency ratios among groups were not significantly different. The weight of epididymal fat in HF + PSEH group, 3.61 ± 0.5 g, or HF + PSEL group, 3.80 ± 0.7 g, was significantly lower than the HF group, 4.39 ± 0.4g, (P < 0.05). Total lipids and total cholesterol in adipose tissue were significantly decreased in HF + PSEH group compared to those in the HF group, respectively (P < 0.05). PSEH supplementation caused AST and ALT levels to decrease when it compared to HF group, but it was not statistically significant. The protein expression of PPARγ in HF + PSEH group was significantly lower than the HF group (P < 0.05). Comparing with the HF group, the protein expression of adiponectin in HF + PSEH group was significantly increased (P < 0.05). The protein expressions of C/EBP α and leptin in HF + PSEH group were lower than the HF group, but it was not statistical significant. In conclusion, peanut sprout extract has anti-obesity effect by lowering the expressions of PPARγ which regulates the expression of adiponectin.

    • "Natural products have the potential to inhibit adipogenesis and induce the apoptosis of mature adipocytes [5,6]. Herbal extracts and phytochemicals have shown anti-obesity effects, especially the down-regulation of the adipogenic transcriptional factors peroxisome proliferator-activated receptor-γ (PPAR-γ) and CCAAT/enhancer binding protein-α (C/EBP-α), the inhibition of fatty acid accumulation, and the stimulation of glycerol-3-phosphate dehydrogenase (GPDH) activity in 3 T3-L1 preadipocytes [7-10]. Berberine, a natural plant product, displays beneficial effects in the treatment of diabetes and obesity at least in part via the stimulation of AMP-activated protein kinase (AMPK) activity [11]. "

    ABSTRACT: Obesity causes metabolic disease and is a serious health problem around the world. Polygonum cuspidatum (POCU1b) has been used clinically for the treatment of constipation, gallstones, hepatitis, and inflammation in East Asian countries. The principal aim of this study was to investigate for the first time whether the extract of Polygonum cuspidatum (POCU) biologically affects adipogenesis in 3 T3-L1 preadipocytes. Fractions (n-hexan, ethyl acetate, n-butanol, and water) of POCU ethanol extract were evaluated in vitro for their inhibitory activities on pancreatic lipase. Of the fractions, the n-butanol of POCU ethanol extract (POCU1b) was examined anti-obesity activity in 3 T3-L1 preadipocytes. To examine the inhibitory effect of POCU1b on adipogenesis, 3 T3-L1 preadipocytes were treated every the other day with POCU1b at various concentrations (0 ~ 25 mug/mL) for twelve days. Oil-red O staining and triglyceride content assay were performed to determine the lipid accumulation. The expression of mRNA and proteins associated lipid accumulation was measured using RT-PCR and Western blotting analysis. We also examined the effect of POCU1b on level of phosphorylated AMP-activated protein kinase (pAMPK) in 3 T3-L1 preadipocytes with POCU1b at various concentrations during adipocyte differentiation. POCU1b exhibited the most pronounced inhibitory effects on pancreatic lipase activity. We found that POCU1b inhibited adipocyte differentiation in 3 T3-L1 preadipocytes in a dose-dependent manner, as evidenced by the reduced formation of lipid droplets and decreased glycerol-3-phosphate dehydrogenase (GPDH) activity. We also showed that the expression levels of adipocyte differentiation-related protein (ADRP) and perilipin (a protein that coats lipid droplets in adipocytes) were both reduced after POCU1b treatment. Peroxisome proliferator-activated receptor-gamma (PPAR-gamma) and CCAAT/enhancer-binding protein-alpha (C/EBP-alpha) proteins, both major adipogenic transcription factors, were markedly reduced by POCU1b. Moreover, ADRP, perilipin, C/EBP-alpha, and PPAR-gamma mRNA levels were also reduced by POCU1b. Levels of phosphorylated AMP-activated protein kinase (pAMPK) were elevated after POCU1b treatment (5, 10, and 25) in a dose-dependent manner. Taken together, these results suggest that the anti-obesity effects of POCU1b involve the inhibition of pancreatic lipase activity and adipogenesis via the down-regulation of lipid accumulation.

    • "We also previously reported that after six days of 10, 20, and 40 µmol/L resveratrol treatment, lipid accumulation and GPDH activity in adipocyte was significantly inhibited as a dose-dependent response (P < 0.05) [34]. Park et al. [35]'s findings were also consistent with our study in showing that resveratrol treatment of 3T3-L1 adipocytes had a significant apoptosis and inhibition of GPDH activity. "

    ABSTRACT: 3T3-L1 preadipocyte were differentiated to adipocytes, and then treated with 0, 10, 20, and 40 µg/mL of peanut sprout ethanol extract (PSEE). The main component of PSEE is resveratrol which contained 5.55 mg/mL of resveratrol. The MTT assay, Oil-Red O staining, glycerol-3-phosphate dehydrogenase (GPDH) activity, and the triglyceride concentration were determined in 3T3-L1 cells. MMP-2 and MMP-9 activities as well as mRNA expressions of C/EBP β and C/EBP α were also investigated. As the concentration of PSEE in adipocytes increased, the cell proliferation was decreased in a dose-dependent manner from 4 days of incubation (P < 0.05). The GDPH activity (P < 0.05) and the triglyceride concentration (P < 0.05) were decreased as the PSEE treatment concentration increased. The mRNA expression of C/EBPβ in 3T3-L1 cells was significantly low in groups of PSEE-treated, compared with control group (P < 0.05). The MMP-9 (P < 0.05) and MMP-2 (P < 0.05) activities were decreased in a dose-dependent manner as the PSEE concentration increased from 20 µg/mL. In conclusion, it was found that PSEE has an effect on restricting proliferation and differentiation of adipocytes.
