dc.description.abstract | Ethnopharmacological relevance: Gangjihwan (DF) which is composed of Ephedra intermedia, Lithospermum erythrorhizon, and Rheum palmatum has been used for the treatment of obesity in traditional medical clinics in Korea. Aim of the study: This study was conducted to standardize DF and elucidate its mechanism of action for inhibiting fat accumulation in adipocytes and adipose tissues. Materials and methods: The herbal ingredients of DF were extracted in water, 30% ethanol or 70% ethanol and freeze-dried followed by HPLC analyses. 3T3-L1 adipocytes and high-fat diet-induced obese mice were treated with each of the three DF preparations. Messenger RNA and protein expression levels were measured by real-time qPCR and Western blotting. RNA-Seq analyses were conducted to examine the effects of DF treatment on whole transcriptome of adipocyte. Results: (-)-Ephedrine and (+)-pseudoephedrine from E. intermedia, aloe-emodin and chrysophanol from R. palmatum and shikonin from L. erythrorhizon were identified as phytochemical components of DF. DF caused dose-dependent inhibition of fat accumulation in 3T3-L1 adipocytes. It also significantly reduced adipose tissue mass and adipocyte size in high-fat diet-induced obese mice. DF was found to down-regulate the expressions of the lipogenic transcription factors such as sterol regulatory element binding protein 1C (SREBP1C), peroxisome proliferator activated receptor gamma (PPAR gamma), and CCAAT/enhancer binding protein alpha (C/EBP alpha). Among the three preparations of DF, the 70% ethanol extract was the most effective. RNA-Seq analyses showed that DF treatment decreased the expression levels of up-regulators and increased those of down-regulators of lipogenic transcription factors. Conclusions: DF preparations, among which 70% ethanol extract was the most effective, reduced fat accumulation in 3T3-L1 adipocytes and high-fat diet-induced obese mice through the down-regulation of lipogenic transcription factors SREBP1C, PPAR gamma and C/EBP alpha. | - |
