Figure 9. Model of how normal and cancer cells regulate the extracellular levels of TGF-β.

The concentration of extracellular TGF-β is maintained by the balance between cellular production of TGF-β and depletion by the endocytosis. The underexpression of Dab2 and impaired TGF-β depletion in cancer cells lead to increased extracellular TGF-β concentration and cancer progression.
