Wnt/β-catenin信号在结肠癌和其他癌症的发病机制中起关键作用;新出现的证据表明,致癌β-连环蛋白调节了癌症发生和发展所必需的几个生物学过程。为了破译β-catenin在转化中的作用,我们对85种癌细胞系的β-catenin活性进行了分类,我们对这些细胞系进行了基因组尺度的功能丧失筛选,发现β-catenin活性的癌症依赖于涉及转录调节因子YAP1的信号通路。具体来说,我们发现YAP1和转录因子TBX5与β-catenin形成复合物。YAP1被酪氨酸激酶YES1磷酸化,导致该复合物定位为抗凋亡基因的启动子,包括BCL2L1和BIRC5。YES1的小分子抑制剂在细胞系和动物模型中都能抑制β-catenin依赖性癌症的增殖。这些观察结果确定了β-catenin-YAP1-TBX5复合物对β-catenin驱动的癌症的转化和存活至关重要。
Wnt/β-catenin signaling plays a key role in the pathogenesis of colon and other cancers; emerging evidence indicates that oncogenic β-catenin regulates several biological processes essential for cancer initiation and progression. To decipher the role of β-catenin in transformation, we classified β-catenin activity in 85 cancer cell lines in which we performed genome scale loss-of-function screens and found that β-catenin active cancers are dependent on a signaling pathway involving the transcriptional regulator YAP1. Specifically, we found that YAP1 and the transcription factor TBX5 form a complex with β-catenin. Phosphorylation of YAP1 by the tyrosine kinase YES1 leads to localization of this complex to the promoters of anti-apoptotic genes including BCL2L1 and BIRC5. A small molecule inhibitor of YES1 impeded the proliferation of β-catenin-dependent cancers in both cell lines and animal models. These observations define a β-catenin-YAP1-TBX5 complex essential to the transformation and survival of β-catenin-driven cancers.
