Inhibition rate of PG, VN, and their combination on gene expression of PPARγ and C/EBPα.

Treatment	PPARγ (%)	C/EBPα (%)
PG 1 mg/mL	19.54 ± 3.62*	32.92 ± 3.34*
VN 1 mg/mL	26.85 ± 2.69**	30.92 ± 2.99*
PG-VN combination 1 mg/mL	35.75 ± 2.07∗∗a	36.32 ± 4.34**
PG-VN combination 2 mg/mL	30.19 ± 1.30∗∗a	39.88 ± 4.15**
xPG + VN	46.39 ± 6.31	63.84 ± 6.33
x(PG + VN)/2	23.195 ± 3.155	31.92 ± 3.165

Values were expressed as means ± SD. *P < 0.05, significantly different from the Control; **P < 0.005, significantly different from the control; ^a P < 0.05, significantly different from PG. ^xCalculated additive response (the sum of the effects of the individual PG and VN treatments). Control, expression of the differentiated 3T3-L1 cells was considered as 0%; PG: Panax ginseng; VN: Veratrum  nigrum.
