An FGFR inhibitor converts the tumor promoting effect of TGF-β by the induction of fibroblast-associated genes of hepatoma cells

2482 views | Aug 16 2017

Zhang HR et al. indicated that FGFR inhibitor treatment converts the effect of TGF-β on the hepatocellular carcinoma cells from tumor promotion into tumor inhibition by enhancing the induction effect of TGF-β on some fibroblast-associated genes. Converting human liver cancer cells into less malignant fibroblast-like cells and inducing tumor parenchyma cell fibrosis provides an alternative strategy for limiting tumor progression.
