目的 观察极光激酶A(AURKA)对前列腺癌细胞活性的影响.方法 使用8条短发卡RNA(shRNA)进行筛选得出2条特异性强的shRNA.在抑制AURKA在前列腺癌细胞DU145的表达后,以噻唑蓝(MTT)法观察前列腺癌细胞活性的变化.结果 2条shRNA抑制DU145的AURKA表达后分别引起DU145活性分别下降40.5% (P<0.01)和61.3% (P<0.01),并使其凋亡比率分别增加9.23% (P<0.05)和15.45%(P<0.05).结论 有效的shRNA片段能够使雄激素受体(AR)不表达的前列腺癌细胞DU145发生AURKA基因沉默,并通过促进凋亡来抑制DU145的活性.

Objective To evaluate the effect of aurora kinase A (AURKA) silencing on the viability of prostate cancer cells.Methods AURKA expression in DU145 cells was inhibited by two specific small hairpin RNAs (shRNAs) from eight shRNAs,and the viability of DU145 cells was documented by methyl thiazol tetrazolium (MTT) assay.Results Inhibition of AURKA by two shRNAs markedly reduced the viability of prostate cancer cells by 40.5% (P < 0.01) and 61.3% (P < 0.01),and increase apoptotic ratio by 9.23 % (P < 0.05) and 15.45 % (P < 0.05),respectively.Conclusion AURKA knockdown of AR-DU145 cells can be achieved by effective shRNA sequences through an apoptosis-promoting approach.
