Antiobesity effects of wild ginseng (Panax ginseng C.A. Meyer) mediated by PPAR-gamma, GLUT4 and LPL in ob/ob mice.Phytother Res. 2009 Feb; 23(2):220-5.PR
The antiobesity effect of wild ginseng (WG; Panax ginseng C.A. Meyer) in male obese leptin-deficient (B6.V-Lepob, 'ob/ob') mice was evaluated. WG was administered orally to mice at doses of 100 mg/kg and 200 mg/kg daily for 4 weeks. The WG-treated ob/ob mice showed a loss of body weight and a decrease in blood glucose levels compared with control mice. WG regulated the mRNA expression level especially, it increased peroxisome proliferators-activated receptors-gamma (PPAR-gamma) and lipoprotein lipase (LPL) in adipose tissue, as well as glucose transporter 4 (GLUT4) and insulin receptor (IR) in the skeletal muscle and liver. Taken together, these results suggest that WG may play a vital role in the antiobesity effect in ob/ob mice; this has importance in insulin sensitivity. This may prove to be of clinical importance in improving the management of obesity and related metabolic syndromes.
