Sci Rep:在雄激素抵抗性前列腺癌模型中,极光激酶A对AR-V7表达的调控

2017-04-05 AlexYang MedSci原创

雄激素受体变异(AR-Vs)提供了雄激素抵抗性前列腺癌(CRPC)治疗逃避的一种机制解释,然而,调控的机制仍旧很多不知道。最近,研究人员调查了在CRPC模型中,极光激酶A在AR-Vs中的角色。研究结果表明了极光激酶A的缺失可以减少AR-V目标基因的表达。有趣的是,极光激酶A的敲除可以对AR前体mRNA进行剪切重构,并且可以有差异的下调AR-V不同转录本的合成,其中包括了AR-V7。但是极光激酶A的

雄激素受体变异(AR-Vs)提供了雄激素抵抗性前列腺癌(CRPC)治疗逃避的一种机制解释,然而,调控的机制仍旧很多不知道。

最近,研究人员调查了在CRPC模型中,极光激酶A在AR-Vs中的角色。研究结果表明了极光激酶A的缺失可以减少AR-V目标基因的表达。有趣的是,极光激酶A的敲除可以对AR前体mRNA进行剪切重构,并且可以有差异的下调AR-V不同转录本的合成,其中包括了AR-V7。但是极光激酶A的敲除并没有对全长AR mRNA的合成产生影响, 然而,AR-V驱使的CRPC细胞的增殖和生存显着的减少了。研究人员指出,这些影响可以通过极光激酶的抑制来进行重复。另外,研究人员展示了极光激酶A的水平在晚期疾病中增加,并且AURKA是一个AR-V目标基因,显示了其在CRPC中雄激素信号的正反馈机制。最后,研究人员表明了极光激酶A在调控AR-V7的表达中起重要作用,并且极光激酶A代表了一个CRPC新的药物靶点。

由于缺乏预测恶性疾病充足的诊断工具,前列腺癌病人往往存在明显的过度治疗的问题。最近,有研究对前列腺癌中PDGFR-β的表达与临床生化前列腺癌复发的相关性进行了研究。血小板产生的生长因子(PDGFs)和它们的受体(PDGFRs)是肿瘤微环境中间充质细胞的关键调控因子。但是,在一些其他的癌症中并没有起到调控因子的作用。研究人员利用一个有535位挪威病人的多中心前列腺癌切除术群体,来调查PDGFR-β和
