Sci Rep:RNF7敲除可以通过钝化ERK1/2通路来抑制前列腺癌肿瘤发生

2017-04-01 AlexYang MedSci原创

去雄抗性的发展是导致前列腺癌病人致死的一个关键的因素。环指蛋白7(RNF7)在癌细胞中的高表达在肿瘤的发展过程中起着关键的角色。然而,RNF7在前列腺癌症发展过程中的角色并没有很好的阐释。最近,研究人员就RNF7在前列腺癌发生中的相关作用进行了研究。在研究中,研究人员在两个去雄抗性前列腺癌细胞系中,分别是DU145和PC3,利用shRNA干扰沉默了RNF7表达。研究人员发现,RNF7的敲除可以减弱

去雄抗性的发展是导致前列腺癌病人致死的一个关键的因素。环指蛋白7(RNF7)在癌细胞中的高表达在肿瘤的发展过程中起着关键的角色。然而,RNF7在前列腺癌症发展过程中的角色并没有很好的阐释。

最近,研究人员就RNF7在前列腺癌发生中的相关作用进行了研究。在研究中,研究人员在两个去雄抗性前列腺癌细胞系中,分别是DU145和PC3,利用shRNA干扰沉默了RNF7表达。研究人员发现,RNF7的敲除可以减弱癌细胞增殖和增强前列腺癌细胞对铂化合物处理的敏感性。另外,RNF7沉默同样也可以减弱DU145和PC3细胞的侵入特性。对此,研究人员指出,这潜在的机制似乎还与肿瘤抑制蛋白(p21、p27、和NOXA)的积累有关,而不仅是RNF7敲除的ERK1/2通路的钝化。总之,研究人员在该研究中,阐释了RNF7敲除诱导了前列腺癌细胞生长抑制和ERK1/2通路的钝化,表明了RNF7也许可以成为一个潜在的新的CRPC药物作用靶点的观点。
