Abstract:

Objective To investigate the effect of dihydroartemisinin on proliferation and apoptosis of human pancreatic cancer cell (PANC-1) and explore its mechanism.Methods After PANC-1cells treated with 30, 60, 120, 240 and 480 μmol/L dihydroartemisinin for 48 hours, MTT assay was used to detect the proliferation effect of dihydroartemisinin on PANC-1 cells. The cell cycle and apoptosis were detected by flow cytometry. The expressions of cyclin B1, Cdk1, p21 and apoptosis related protein Bcl-2, Bax, Caspase-3, Caspase-9 and cytochrome C(Cyto C) were detected by Western blotting. Results MTT result showed that the proliferation of PANC-1 cells was inhibited obviously after treatment with dihydroartemisinin by the concentration of 30-480 μmol/L (P<0.05). The result of flow cytometry showed that dihydroartemisinin could block PANC-1 cell cycle in G2/M phase and induce cells apoptosis (P<0.05). The result of Western blotting showed that the expressions of Cdk1 and cyclin B1 were decreased and the expression of P21 increased after treatment with dihydroartemisinin. The expression of Bcl-2 was downregulated, expression of Bax was up-regulated, the ration of Bax/Bcl-2 was increased and the expression of cleaved Caspase-3, cleaved Caspase-9 and Cyto C were up-regulated. Conclusion Dihydroartemisinin can inhibit the proliferation of PANC-1 cells and induce apoptosis. The possible mechanism might be related to mitochondrial pathway.
