[Effect of turmeric volatile oil on proliferation and apoptosis of human skin SCC A431 cells].

To investigate the effect of turmeric volatile oil (TVO) on the apoptosis and proliferation of human skin SCC A431 cells, A431 cells were incubated with different concentrations (5-80 mg•L⁻¹) of TVO in vitro．The proliferation and cell cycle were assessed by CCK8 assay. The change of morphology was observed with inverted microscope. Apoptosis was evaluated with AO/EB double staining and flow cytometry (FCM); cell cycle was analyzed with FCM ．Western blot method was used to detect caspase-3 and caspase-9 protein expression.
