Oncogene:PDZ结合激酶和雄激素受体相互反馈能够驱使前列腺癌发生

2018-10-08 AlexYang MedSci原创

阐释雄激素受体(AR)活性增加和随后恶性前列腺癌(PrCa)发展的潜在的机制在发展新的理论方面是非常关键的。最近,有研究人员利用系统生物学的方法,分析了AR调控的蛋白组,并坚定了一个新的AR调控的蛋白-PDZ结合激酶(PBK),该蛋白能够在PrCa中调节全程AR和AR变异体的活性。PBK在恶性PrCa中的过表达与早期生化复发和不良临床结果相关。除了碳末端配体结合区域,PBK还可以与AR的氮末端反式

阐释雄激素受体(AR)活性增加和随后恶性前列腺癌(PrCa)发展的潜在的机制在发展新的理论方面是非常关键的。

最近,有研究人员利用系统生物学的方法,分析了AR调控的蛋白组,并鉴定了一个新的AR调控的蛋白-PDZ结合激酶(PBK),该蛋白能够在PrCa中调节全程AR和AR变异体的活性。PBK在恶性PrCa中的过表达与早期生化复发和不良临床结果相关。除了碳末端配体结合区域,PBK还可以与AR的氮末端反式激活结构域互作来使其稳定,进一步引起AR蛋白在PrCa中表达的增加。转录组测序阐释了PBK是AR信号的一个调控因子,并且在肿瘤入侵和转移中具有重要的作用。PBK的抑制能够减少PrCa细胞系和体外培养临床活检样本的生长。

最后,研究人员指出,他们阐释了AR和PBK之间的一个新的相互作用,该作用能够导致AR和ARVs表达的增加,从而引起AR调控的PrCa的生长和恶化。他们的研究结果在开发PBK抑制剂从而对PrCa进行治疗上是有意义的。
