J Exp Clin Cancer Res:YAP通过增强Wnt/β-连环蛋白信号传导来促进胶质瘤的生长

2018-02-07 MedSci MedSci原创

已知Hippo/YAP通路对于发育、生长和器官发生来说十分重要,并且该通路的失调将导致肿瘤的进展。研究发现YAP在人胶质瘤中上调并与患者的预后较差相关。然而,YAP在胶质瘤发展中的作用和机制在很大程度上是未知的。采用定量聚合酶链反应(qPCR)和免疫印迹法检测胶质瘤组织中YAP的表达。使用细胞生长测定和颅内胶质瘤模型检查YAP对神经胶质瘤进展的影响。通过免疫印迹、免疫荧光和RT-PCR检测YAP对

已知Hippo/YAP通路对于发育、生长和器官发生来说十分重要,并且该通路的失调将导致肿瘤的进展。研究发现YAP在人胶质瘤中上调并与患者的预后较差相关。然而,YAP在胶质瘤发展中的作用和机制在很大程度上是未知的。

采用定量聚合酶链反应(qPCR)和免疫印迹法检测胶质瘤组织中YAP的表达。使用细胞生长测定和颅内胶质瘤模型检查YAP对神经胶质瘤进展的影响。通过免疫印迹、免疫荧光和RT-PCR检测YAP对β-catenin蛋白水平、亚细胞定位和转录活性的影响。

结果显示,YAP的敲低抑制体外胶质瘤细胞增殖和体内肿瘤生长。此外,YAP通过调节GSK3β的活性调节了β-catenin的蛋白水平、亚细胞定位和转录活性。最后,β-catenin部分介导了YAP对神经胶质瘤细胞增殖的影响。

总之,该研究结果表明,YAP通过增强Wnt/β-连环蛋白信号传导来促进人类胶质瘤的生长。此外,本研究提供了Hippo/YAP和Wnt/β-catenin通路之间的新的串扰机制,这为人类胶质瘤治疗提供了新的策略。
