Conclusions

Our study demonstrates a requirement of VASP for TGF-β-mediated HSC activation in the tumor microenvironment by regulating Rab11-dependent recycling of TβRII to the plasma membrane. VASP and its effector, Rab11, in the tumor microenvironment thus present therapeutic targets for reducing TI and metastatic growth in the liver.
