摘要: 转化生长因子β(Transforming growth factor-β,TGF-β)通路在调节细胞生长、分化和迁移中的显著作用决定了该信号通路在癌细胞的进展过程中也具有至关重要的作用。TGF-β通过经典和非经典的这两类信号转导途径来改变细胞的表型,发挥着肿瘤抑制或肿瘤促进的作用。TGF-β通过诱导上皮-间充质细胞转化(Epithelial-mesenchymal transition,EMT)来驱动肿瘤细胞进程,同时在这个过程中上皮细胞获得新的间充质的表型,使肿瘤细胞的转移能力和侵袭能力增强。这证明了TGF-β通路是促进肿瘤发展的因素。然而也有相反的证据表明,癌细胞中TGF-β信号转导途径的缺失与阻断也可以导致肿瘤细胞转移能力的增强。这篇综述回顾TGF-β对肿瘤微环境组成部分的调节和这种调节如何引起肿瘤进展作相关研究。

Abstract: The transforming growth factor-β(TGF-β)pathway has been established as essential for cancer progression,because of its prominent role in the regulation of cell growth,differentiation and migration.Through the canonical and non-canonical arms of the signaling pathway,TGF-β instigates cellular phenotypical changes that mediate its role as both tumour suppressor and tumour promoter.TGF-β acts as a potent driver of cancer progression through the induction of epithelial-mesenchymal transition(EMT),in which epithelial cells acquire mesenchymal phenotype,leading to enhanced motility and invasion.It is evidence of the TGF-β pathway being tumour suppressive.However,there is also evidence to the contrary,abrogation of TGF-β signalling in carcinoma cells can also result in increased metastasis.This review addresses the experiments about role of an essential signalling pathway,that of transforming growth factor-β,in the regulation of components of the tumour microenvironment and research of how this contributes to tumour progression.
