Herein, we show that the abundance of endoglin (ENG), a TGF-β superfamily coreceptor expressed on human breast myCAFs, is significantly associated with poorer outcomes of breast cancer patients.

Mechanistically, ENG facilitates TGF-β-Smad2/3 signaling in myCAFs, presumably through association with a TGF-β ligand-receptor complex, leading to self-stimulating TGF-β1 production. Stromal TGF-β1, in turn, induces partial epithelial-mesenchymal transition in cancer cells in a paracrine manner, resulting in suppression of primary tumor growth and promotion of invasion and metastasis. ENG-primed TGF-β autocrine signaling also produces other factors that could mediate primary tumor growth promotion by myCAFs.

Whether the transition between these dichotomous functions involves modulation of the senescence phenotype during disease progression remains elusive. Exploiting the epithelial HCC cell line Huh7 as a robust model, we demonstrate that chronic exposure to TGF-β prompts escape from Smad3-mediated senescence, leading to the development of TGF-β resistance. This altered state is characterized by an optimal proliferation rate and the acquisition of molecular and functional traits of less-differentiated mesenchymal cells, coinciding with differential growth capacity in 2D and 3D culture conditions, epithelial-to-mesenchymal transition (EMT), and increased invasiveness in vitro, and metastasis in vivo.

An integrated transcriptomic landscape reveals both shared and distinct gene signatures associated with senescent and TGF-β resistant states. Importantly, genetic ablation and molecular studies identify microtubule affinity regulating kinase 1 (MARK1) and glutamate metabotropic receptor 8 (GRM8) as critical modulators of the resistance phenomenon, potentially by impairing spatiotemporal signaling dynamics of Smad activity.
