Sci Rep:在雄激素抵抗前列腺癌中, REST是一个在类EMT和干细胞表型的获得中的关键调控因子

2017-04-02 AlexYang MedSci原创

雄激素抵抗性前列腺癌(CPRC),同样也称为激素难治性前列腺癌(HRPC),需要引起人们适当的注意,因为它不仅对雄激素阻断治疗、化疗和放疗有抗性,而且还具有高度可转移性特点。越来越多的证据显示,神经内分泌细胞(NE)的富集和CRPC有关。最近,研究人员通过直接的Twist1和CD44转录的抑制,结合RNA-seq和CHIP-seq分析,阐释了REST参与了上皮间质转化(EMT)和NE分化的前列腺癌

雄激素抵抗性前列腺癌(CPRC),同样也称为激素难治性前列腺癌(HRPC),需要引起人们适当的注意,因为它不仅对雄激素阻断治疗、化疗和放疗有抗性,而且还具有高度可转移性特点。越来越多的证据显示,神经内分泌细胞(NE)的富集和CRPC有关。

最近,研究人员通过直接的Twist1和CD44转录的抑制,结合RNA-seq和CHIP-seq分析,阐释了REST参与了上皮间质转化(EMT)和NE分化的前列腺癌细胞细胞(PCa)干细胞特性的获得。特别地,研究人员展示了短期REST敲除诱导了LNCaP细胞的NE分化,而对应的长期REST敲除增强了Twist1和CD44的表达、细胞迁移和球体形成。研究还指出,在雄激素抵抗的CWR22Rv1 PCa细胞中,REST的超表达可以显着的减少Twist1和CD44的表达、细胞迁移和球体形成。最后,研究人员指出,该研究揭示了REST在NE PCa细胞中对EMT和干细胞特性的调控作用,并表明了REST是CRPC药物作用的潜在靶点的观点。
