Effect experimentation of curcumol on proliferation and apoptosis of human glioma U251 cell / 国际外科学杂志

ABSTRACT

Objective To observe the effect of the active ingredient present study curcumol impact on human glioma cell line U251 proliferation and apoptosis,its effect on the detection of apoptosis-related gene expression in glioma,and explore the possible mechanism of its anti-glioma,Chinese herbal medicine for the treatment of glioma accumulation of experimental data.Methods In cultured human glioma cell line U251 as a model to medium dilution Curcumol different concentrations,observation and detection followingMTT assay at different times,different concentrations curcumol on U251 cell proliferation;microscope Effect of different concentrations of curcumol U251 cell morphology;affected by flow cytometry curcumol different concentrations on apoptosis in U251;RT-PCR method to detect different concentrations curcumol on U251 cell apoptosis-related gene bcl-2 and COX-2 expression levels of influence.Results Curcumol U251 human glioma cell proliferation inhibition effect and showed concentration-dependent and time-dependent manner (P ＜ 0.05).Conclusions Curcumol U251 human glioma cell proliferation clear.Induce apoptosis and inhibit proliferation of glioma should be an important mechanism of inhibition of proliferation effect of curcumol.Curcumol down on U251 cells bcl-2 gene expression levels and COX-2should be its induction of apoptosis,an important mechanism of inhibition of proliferation.
