Samul-Tang Regulates Cell Cycle and Migration of Vascular Smooth Muscle Cells against TNF-α Stimulation

Figure 2

Effect of SMT on TNF-α stimulated expression of cell cycle regulators. (a) cyclin D1 and CDK4, (b) cyclin E and CDK2, and (c) and . Cells were treated with TNF-α (10 ng/ml) for 24 h in the absence or pretreatment of SMT (10, 30, and 50 μg/ml) for 30 min. Bar represents the mean ± SEM of 3 independent experiments. and versus untreated control group. and versus TNF-α-treated group.
