Brit J Cancer:使用剪接寡核苷酸靶向ERG致瘤基因来治疗前列腺癌的研究

ERG致瘤基因是ETS转录因子家族的一个成员,是前列腺癌的遗传驱使因子。在50%的案例中通过与雄激素响应的TMPRSS2启动子融合被激活。因此,在开发靶向ERG的药物上研究较热。最近,有研究人员通过反义的方法,设计了一个基于吗啉代的寡核苷酸通过跳过第4外显子来靶向ERG。

研究发现,在VCaP细胞中,设计的2个剪接寡核苷酸(SSOs)在诱导第4外显子跳过中均有效。在单一的一次转染后,总的ERG蛋白水平减少持续时间高达96小时。SSO诱导的ERG减少能够减弱细胞增殖、细胞迁移和显著在增加细胞凋亡。研究人员还观察到了cyclin D1、c-Myc和Wnt信号通路成员catenin以及激活Wnt信号的标记p-LRP6蛋白水平均同时减少。研究人员在小鼠的MG63异种种植模型中测试了3'剪接位点SSO,发现肿瘤生长减少。研究人员还阐释了SSO的3'剪接位点能够在患者来源的前列腺癌组织中减少ERG的表达。

最后,研究人员指出,他们成功的设计和测试了基于吗啉代的SOs,能够ERG表达减少,从而进一步减少细胞增殖、细胞迁移和增加细胞凋亡。小鼠和人类前列腺癌样本测试表明了SSOs能够有效的靶向致瘤基因。因此,他们的研究鼓舞了人们需要进一步的在体内测试SSOs靶向ERG致瘤基因的效果。
