1 Integrated analysis of multiple receptor tyrosine kinases identifies Axl as a therapeutic target and mediator of resistance to sorafenib in hepatocellular carcinoma. Sorafenib AXL receptor tyrosine kinase Homo sapiens
2 We explored the biologic significance and preclinical efficacy of Axl inhibition as a therapeutic strategy in sorafenib-naive and resistant HCC. Sorafenib AXL receptor tyrosine kinase Homo sapiens
3 METHODS: We evaluated Axl expression in sorafenib-naive and resistant (SR) clones of epithelial (HuH7) and mesenchymal origin (SKHep-1) using antibody arrays and confirmed tissue expression. Sorafenib AXL receptor tyrosine kinase Homo sapiens
4 We confirmed sorafenib resistance to be associated with EMT and enhanced motility in both HuH7-SR and SKHep-1-SR cells documenting a 4-fold increase in Axl phosphorylation as an adaptive feature of chronic sorafenib treatment in SKHep-1-SR cells. Sorafenib AXL receptor tyrosine kinase Homo sapiens
5 Axl inhibition reduced motility and enhanced sensitivity to sorafenib in SKHep-1SR cells. Sorafenib AXL receptor tyrosine kinase Homo sapiens
6 In patients treated with sorafenib (n = 40), circulating Axl levels correlated with shorter survival. Sorafenib AXL receptor tyrosine kinase Homo sapiens
7 CONCLUSIONS: Suppression of Axl-dependent signalling influences the transformed phenotype in HCC cells and contributes to adaptive resistance to sorafenib, providing a pre-clinical rationale for the development of Axl inhibitors as a measure to overcome sorafenib resistance. Sorafenib AXL receptor tyrosine kinase Homo sapiens
8 CONCLUSIONS: Suppression of Axl-dependent signalling influences the transformed phenotype in HCC cells and contributes to adaptive resistance to sorafenib, providing a pre-clinical rationale for the development of Axl inhibitors as a measure to overcome sorafenib resistance. Sorafenib AXL receptor tyrosine kinase Homo sapiens
9 CONCLUSIONS: Suppression of Axl-dependent signalling influences the transformed phenotype in HCC cells and contributes to adaptive resistance to sorafenib, providing a pre-clinical rationale for the development of Axl inhibitors as a measure to overcome sorafenib resistance. Sorafenib AXL receptor tyrosine kinase Homo sapiens
10 CONCLUSIONS: Suppression of Axl-dependent signalling influences the transformed phenotype in HCC cells and contributes to adaptive resistance to sorafenib, providing a pre-clinical rationale for the development of Axl inhibitors as a measure to overcome sorafenib resistance. Sorafenib AXL receptor tyrosine kinase Homo sapiens
