Epithelial cells repress epithelial characteristics and elaborate mesenchymal characteristics to migrate to other locations and acquire new properties. Epithelial plasticity responses are directed through cooperation of signaling pathways, with TGF-β and TGF-β-related proteins playing prominent instructive roles. Epithelial-mesenchymal transitions (EMTs) directed by activin-like molecules, bone morphogenetic proteins, or TGF-β regulate metazoan development and wound healing and drive fibrosis and cancer progression. In carcinomas, diverse EMTs enable stem cell generation, anti-cancer drug resistance, genomic instability, and localized immunosuppression. This review discusses roles of TGF-β and TGF-β-related proteins, and underlying molecular mechanisms, in epithelial plasticity in development and wound healing, fibrosis, and cancer.
上皮细胞抑制上皮特征,并表现出间充质特征,以迁移到其他位置并获得新的特性。上皮细胞可塑性反应是通过信号通路的合作来指导的,其中 TGF-β 和 TGF-β 相关蛋白起着突出的指导作用。由激活素样分子、骨形态发生蛋白或 TGF-β 指导的上皮-间充质转化 (EMT) 调节后生动物的发育和伤口愈合,并推动纤维化和癌症的进展。在癌中,不同的 EMT 使干细胞生成、抗癌药物耐药性、基因组不稳定性和局部免疫抑制成为可能。这篇综述讨论了 TGF-β 和 TGF-β 相关蛋白在发育和伤口愈合、纤维化和癌症中的上皮可塑性中的作用和潜在的分子机制。
