摘要
目的 观察组蛋白修饰相关基因对前列腺癌细胞DU145活性的影响.方法 利用短发夹RNA (shRNA)使前列腺癌细胞DU145的44种组蛋白修饰相关基因发生沉默,观察哪些基因对DU145增殖呈正向调节作用.结果 44种组蛋白修饰相关基因中的9种基因[极光激酶A(AURKA)、组蛋白调节基因(HIRA)、多梳增强子1基因(EPC1)、拟南芥驱动蛋白2A基因(KAT2A)、拟南芥驱动蛋白2B基因(KAT2B)、拟南芥驱动蛋白5基因(KAT5)、拟南芥驱动蛋白6B基因(KAT6B)、组蛋白去乙酰化酶1基因(HDAC1)、组蛋白去乙酰化酶6基因(HDAC6)]对DU145细胞的增殖起到正向调节作用.9种基因中,4个挑选出来的基因:KAT2B、KAT5、KAT6B和HDAC1以基因特异性的方式,对DU145细胞活性的抑制率分别为41%、61%、36%和20% (P<0.05).结论 KAT2B、KAT5、KAT6B和HDAC1作为组蛋白修饰相关基因,可以基因特异性的方式促进前列腺癌细胞DU145的增殖.
Objective To observe the role played by genes involved in histone modification in viability of prostate cancer cells.Methods An RNAi screening with 44 genes involved in histone modifications was applied to a prostate cancer cell line,DU145.Results Nine genes [aurora kinase A (AURKA),histone regulation (HIRA),enhancer of polycomb (EPC1),kinesins from arabidopsis thaliana (KAT2A),kinesins from arabidopsis thaliana (KAT2B),kinesins from arabidopsis thaliana (KAT5),kinesins from arabidopsis thaliana (KAT6B),histone deacetylase 1 (HDAC1),histone deacetylase 6 (HDAC6)] could positively regulate the proliferation of DU145 cells (P < 0.05),and four selected genes (KAT2B,KAT5,KAT6B and HDAC1) were found to exert this effect by a gene-specific manner when silenced with a inhibition rate of 41%,61%,36% and 20% (P < 0.05).Conclusion As histone modification genes,KAT2B,KAT5,KAT6B and HDAC1 might promote the proliferation of DU145 cells.
