- 生物化学分析证实TBDi与TEAD的直接结合.
- 转录组分析以评估基因表达的变化.
- 细胞增殖测试用于评估功能影响.
主要成果:
- 一种新型的,TBDi,旨在专门抑制YAP-TEAD相互作用.
- TBDi直接与TEAD结合,阻断YAP结合和TEAD的转录活动.
- 治疗TBDi降低了YAP/TEAD目标基因的调节 (例如,CYR61,CTGF).
- TBDi强烈抑制了癌细胞的扩散,与YAP/TAZ敲击相比.
结论:
- TBDi是YAP-TEAD信号轴的强有力的和特定的抑制剂.
- TBDi显示出作为YAP驱动疾病的治疗剂的显著潜力.
- 这项研究提供了一种基于的新策略,用于针对癌症治疗中的YAP.
