Sci Rep:前列腺癌细胞中AR无差异抗雄激素抗性驱使因子分析

2019-10-08 AlexYang MedSci原创

二代抗雄激素类药物抑制雄激素受体(AR)是转移去势抵抗性前列腺癌(mCRPC)的标准治疗方法,但是不可避免的会导致抗性的产生。自从高效AR信号抑制剂的使用,大于20%的mCRPC的患者发展为不依赖AR抗性机制疾病。最近,有研究人员开发了2个抗雄激素药物和不依赖AR活性的去势抵抗性前列腺癌细胞模型,尽管模型中AR表达强烈(AR无差异)。这些模型对所有当今的AR信号抑制剂存在抗性。研究发现,这2个细胞

二代抗雄激素类药物抑制雄激素受体(AR)是转移去势抵抗性前列腺癌(mCRPC)的标准治疗方法,但是不可避免的会导致抗性的产生。自从高效AR信号抑制剂的使用,大于20%的mCRPC的患者发展为不依赖AR抗性机制疾病。

最近,有研究人员开发了2个抗雄激素药物和不依赖AR活性的去势抵抗性前列腺癌细胞模型,尽管模型中AR表达强烈(AR无差异)。这些模型对所有当今的AR信号抑制剂存在抗性。研究发现,这2个细胞系模型由于MCL1表达的上调均表现除了对化疗药物多烯紫杉醇的交叉抗性。但是仍旧对PARP抑制剂奥拉帕尼和pan-BCL抑制剂obatoclax保持敏感性。抗雄激素抗性细胞系的RNA-seq分析鉴定了E2F细胞周期主调控子的超活化状态,并且是AR无差异生长的驱使因子,并且是周期蛋白D/E、E2F1和RB1的下调以及Myc活性的增加引起。重要的是,mCRPC低AR活性组织样本展现出了相同的变化和E2F1活性的增加。

最后,研究人员指出,他们描述了2个细胞学模型,能够模仿治疗诱导产生的AR不依赖表型,该表性对化疗具有交叉抗性且有E2F超活化驱使。
