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

Treatment	PPARγ (%)	C/EBPα (%)
PG 1 mg/mL	21.52 ± 5.28*	43.42 ± 6.80**
VN 1 mg/mL	26.29 ± 3.47*	40.65 ± 2.08**
PG-VN combination 1 mg/mL	28.87 ± 2.25*	39.61 ± 3.82*
PG-VN combination 2 mg/mL	45.22 ± 3.88∗∗ab	59.94 ± 1.94∗∗b
xPG + VN	47.81 ± 8.75	84.07 ± 8.88
x(PG + VN)/2	23.905 ± 4.375	42.035 ± 4.44

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; ^b P < 0.05, significantly different from VN. ^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.
