Abstract (original English)
Background Platycodi Radix (root of Platycodon grandiflorum) and its active compound platycodin D (PD) has been previously shown to possess anti-obesity properties, but the underlying mechanisms remain poorly understood. Purpose The present study was aimed to evaluate the anti-obese effect of PD and reveal its mechanism of action. Study design/methods Genetically obese db/db mice were orally treated with PD for 4 weeks, and body weight gain, adipose tissue weight, serum parameters were measured. Then, assays on adipogenic factors, thermogenic factors, and AMP-activated protein kinase (AMPK) pathway were performed in PD-treated 3T3-L1 murine adipocytes, human adipose-derived mesenchymal stem cells (hAMSCs), and primary cultured brown adipocytes. Results PD treatment attenuated body weight gain, suppressed white adipose tissue weight and improved obesity-related serum parameters in db/db mice. Two major adipogenic factors, peroxisome proliferator-activated receptor gamma (PPARγ) and CCAAT/enhancer binding protein α (C/EBPα) were decreased by PD treatment in WAT of db/db mice, 3T3-L1 adipocytes and hAMSCs. In BAT of db/db mice and primary cultured brown adipocytes, PD treatment elevated the expressions of uncoupled protein 1 (UCP1) and peroxisome proliferator-activated receptor γ coactivator 1 α (PCG1α), the key regulators of BAT-associated thermogenesis. In addition, PD activated
