(a) Serum starved VSMCs were pretreated with indicated concentrations of CJF followed by stimulation with TNF-α (100 μg/mL) for 24 h. Cell proliferation was measured by MTT assay and values are expressed as means ± SEM (n = 5). ^∗ P < 0.05, ^∗∗ P < 0.01, ^∗∗∗ P < 0.001, significant difference versus control. (b) Serum starved VSMCs were treated with indicated concentrations of CJF without stimulation for 24 h. Cell viability was measured by MTT assay. Results are shown as means ± SEM (n = 5). ^∗ P < 0.05, significant difference versus control.
