TGF-β induces chemoresistance in HepG2 cells. (a and b) MTT and clonogenic assay of HepG2 cells sensitized with recombinant TGF-β alone or in combination with LY2157299 in presence of Sorafenib or doxorubicin. Asterisks represent significant differences (p< 0.05 (*), p < 0.005 (**), p < 0.0005 (***)). Data are mean ± SD or representative of three independent experiments performed in triplicate.
