[Effects of Oridonin combined with Capecitabine on the proliferaction of MDA-MB-231 human breast cancer cells].
To investigate the effects of oridonin combined with capecitabine on the proliferaction of MDA-MB-231 human breast cancer cells.Effect of different concentrations(10, 20 and 40μmol/L)of oridonin, capecitabine and their combination on the proliferation of MDA-MB-231 cells after incubation for 24 or 48 h was studied. Then, the effect of 5 μmol/L of oridonin, capecitabine and their combination on cell colony formation was detected. Finally, influence of 20 μmol/L of oridonin, capecitabine and their combination on morphological alteration of nucleus, cell cycle and apoptosis was explored.The inhibition rate on MDA-MB-231 cells after incubation with 20μmol/L oridonin or capecitabine for 48 h was 49.5% and 58.6%, respectively, while the inhibition rate against proliferation of MDA-MB-231 cells reached 94.6% with combination of 20 μmol/L oridonin and capecitabine. Cells incubated with combination of oridonin and capecitabine formed fewer and smaller colonies (
