Transforming growth factor ? (TGF?) is a multifunctional cytokine which is importantly implicated in hepatocarcinogenesis. The current study provides novel evidence that TGF? upregulates the expression of multiple receptor tyrosine kinases (RTKs), including IGF1R, EGFR, PDGF?R, and FGFR1 in human hepatocellular carcinoma (HCC) cells. This, in turn, sensitized HCC cells to individual cognate RTK ligands, leading to cell survival. Our data showed that the TGF?-mediated increase in growth factor sensitivity led to evasion of apoptosis induced by the mutikinase inhibitor, sorafenib. Conversely, we observed that inhibition of the TGF? signaling pathway by LY2157299, a TGF?RI kinase inhibitor, enhanced sorafenib-induced apoptosis, in vitro. Our findings disclose an important interplay between TGF? and RTK signaling pathways, which is critical for hepatocellular cancer cell survival and resistance to therapy.
