We aimed to explore the antiadipogenic and adipolysis effect of hesperetin in human mesenchymal stem cells (hMSCs)-induced adipogenesis. IC50 value of hesperetin was higher for hMSCs such as 149.2 ± 13.2 μmol for 24 h and 89.4 ± 11.4 μmol in 48 h, whereas in preadipocytes was 87.6 ± 9.5 μmol and 72.4 ± 5.6 μmol in 24 h and 48 h, respectively. Hesperetin treatment (5, 10, and 20 μmol) to adipogenesis-induced hMSCs (Group 1) and preadipocytes (Group 2) resulted in a significantly (p < 0.05) increased lipolysis. The treatment with hesperetin decreased the expression of resistin, adiponectin, aP2, LPL, PPAR-γ, and TNF-α in Groups 1 and 2, whereas a significant increase was observed in Bcl, Bax, and p21 expression in Group 2 compared to untreated preadipocytes. hMSCs cultured in adipogenic medium along with hesperetin significantly inhibited adipocyte differentiation and increased the proapoptotic gene expression levels in preadipocyte. Our result indicates the antiadipogenic and adipolysis effects of hesperetin.

In this study, we examined the effects of Aloe-emodin (AE) on the inhibition of adipocyte differentiation during 3-isobutyl-1-methylxanthine (IBMX)-induced adipocyte differentiation in human mesenchymal stem cells (hMSCs). AE treatment (5, 10, and 20 µM) of preadipocyte cells resulted in a significant (p < 0.05) decrease in glycerol phosphate dehydrogenase and triglyceride levels as well as an increase in lactate dehydrogenase activity and attenuated lipid accumulation compared with untreated differentiated adipocytes.

Unlabelled: The mechanisms by which androgens regulate fat mass are poorly understood. Although testosterone has been reported to increase lipolysis and inhibit lipid uptake, androgen effects on proliferation and differentiation of human mesenchymal stem cells (hMSCs) and preadipocytes have not been studied. Here, we investigated whether dihydrotestosterone (DHT) regulates proliferation, differentiation, or functional maturation of hMSCs and human preadipocytes from different fat depots. Read More

Citrus flavonoids are reported to be promising bioactive compounds against hyperlipidemia and lipid biosynthesis. However, the mechanism of the lipid lowering effect by flavonoids remains unknown. The present study examines the effect of some flavanones on the adipocytic conversion of the human preadipocyte cell line, AML-I. Read More

Genistein (G) and resveratrol (R) individually inhibit adipogenesis in 3T3-L1 adipocytes and induce apoptosis in cancer cells. We investigated whether the combination of G and R resulted in enhanced effects on adipogenesis, lipolysis, and apoptosis in 3T3-L1 cells. Preadipocytes and mature adipocytes were treated with G and R individually at 50 and 100 micromol/L (G100; R100) and in combination. Read More
