Blood:CDK 6与骨髓增生性肿瘤

2019-04-13 MedSci MedSci原创

研究发现了CDK 6对骨髓增生性肿瘤进展过程中的作用,为疾病的治疗提供新的依据

80%以上的骨髓增生性肿瘤(MPNs)患者体内存在JAK2V617F突变,导致大多数患者对Jak抑制剂治疗无应答,对于这部分患者需要开发新的治疗方法。

近日研究人员发现CDK 6在MPN进化过程中发挥了关键作用。模型研究证实CDK 6抑制可改善临床症状,延长生存期。CDK 6蛋白紊乱相关疾病疾病的特征为:CDK6参与恶性干细胞静止调节、促进核因子κb(NF-κb)信号转导、抑制细胞凋亡同时促进细胞因子的产生。上述效益不受Palbociclib干扰,表明CDK 6在MPN发病机制中的作用很大程度上是与激酶无关的。
