Effects of ginseng extract (GE) and testosterone (T) on adipogenesis-associated gene expression in high-fat diet (HFD)-fed castrated mice. (A) Mice were fed a low-fat diet (LFD), HFD, or HFD supplemented with GE and/or T for 8 weeks. Relative mRNA levels of PPARγ, C/EBPα, and aP2 are expressed as mean ± SD using β-actin as a reference gene. #P<0.05 versus LFD group. *P<0.05 versus HFD group. **P<0.05 versus T group. (B) Representative RT-PCR bands from one of three independent experiments are shown.
