ABSTRACT
OBJECTIVE@#Dihydroartemisinin is a traditional anti-malarial drug, a derivative of the artemisinin, it has anti-tumor activity of a variety of tumor cells. This study investigated the effect of growth inhibition of nasopharyngeal carcinoma cells line CNE-2 induced by dihydroartemisinin and its possible mechanism.@*METHOD@#The effect of DHA on the cell proliferation of CNE-2 was detected by CCK-8 assay with different concentrations and time. The effects of DHA on the cell apoptosis of CNE-2 were detected by Annexin V-FITC assay through flow cytometry and caspase-3 activity assay.@*RESULT@#CCK-8 experimental results show that CNE-2 cell proliferation was suppressed with DHA treatment, as compared with the control group. DHA could induce marked apoptosis in CNE-2 by apoptosis assay, as compared with the control group, The percentages of apoptotic cells increased along with the increase of DHA concentrations in CNE-2; The activity of caspase-3 was increased following DHA treatment in a dose-dependent manner.@*CONCLUSION@#DHA could effectively inhibit proliferation and induce apoptosis of human nasopharyngeal carcinoma cells line CNE-2, the possible mechanism DHA induce apoptosis of CNE-2 cells by upregulating the expression of caspase-3.
