Abstract

Although human cancers exhibit intratumour heterogeneity, the influence of the tumour environment on this property is unclear. Single basal-like mammary epithelial cells are now shown to engage a dynamic TGFBR3-JUND signalling circuit in an extracellular-matrix-dependent manner. Cell transition between the distinct gene expression states underlying this circuit alters their properties and may modulate their propensity to malignancy.

摘要

尽管人类癌症表现出肿瘤内异质性,但肿瘤微环境对其的影响尚不清楚。现在发现,单个基底样乳腺上皮细胞以细胞外基质依赖的方式激活一个动态的 TGFBR3-JUND 信号通路。该通路所依赖的不同基因表达状态下的细胞转换改变了它们的特性,并可能调节它们的恶性倾向。
