CDH1)基因和蛋白表达水平。结果:不同浓度DHA均能显著抑制PC-3和DU145迁移和侵袭能力(P<0.001)。不同浓度DHA均能明显下调Vimentin m RNA和蛋白的表达(P<0.05)
上调CDH1 m RNA和蛋白的表达(P<0.05)。结论:双氢青蒿素能显著抑制人前列腺癌细胞的迁移和侵袭能力
其可能机制是DHA干扰Vimentin表达及诱导E-Cadherin表达
且高浓度DHA可能存在其他途径抑制前列腺癌细胞的迁移和侵袭能力。
Abstract
Objective:To investigate the effects of dihydroartemisinin(DHA)on cell migration and invasion in human prostate cancer cells and its underlying molecular mechanisms. Methods:PC-3 and DU145 cells were treated with different concentrations(0
25
50
100 μmol/L)of DHA for 48 h. The migration and invasion abilities of PC-3 and DU145 cells were examined using the cell migration and invasion assays. Vimentin and E-cadherin(CDH1)m RNA and protein expression levels were determined by RT-q PCR and Western blot respectively. Results:DHA can significantly inhibit cell migration and invasion of PC-3 and DU145 cells(P<0.001). The expression levels of Vimentin m RNA and protein were significantly decreased(P<0.05)
while the expression levels of CDH1 m RNA and protein were increased(P<0.05). Conclusion:DHA significantly inhibits the migration and invasion abilities of PC-3 and DU145 cells in vitro. These mechanisms may relate with the reduced expression of vimentin and the induced expression of CDH1 by DHA.In addition to inhibitting EMT
high concentration of DHA may inhibit the migration and invasion abilities of PC-3 and DU145 cells by other ways.
