Alcohol induces sorafenib resistance in hepatocellular carcinoma: A translational study.

ABSTRACT: Alcohol is a major cause of hepatocellular carcinoma (HCC), accounting for 30% of cases worldwide. Sorafenib, a tyrosine kinase inhibitor (TKI), was the standard first-line treatment for advanced HCC until 2021, but sorafenib resistance is common. We explored the impact of chronic alcohol exposure (CAE) on sorafenib response and sought to identify associated resistance mechanisms. Huh-7 HCC cells were chronically exposed to alcohol for 6 months. Sorafenib resistance was assessed by measuring cell viability (IC50) and by evaluating the protein expression of signaling pathways involved in resistance using immunoblotting. RNA sequencing was performed to identify mechanisms of resistance. Sorafenib response was assessed using the RECIST 1.1 criteria in HCC patients. A retrospective study of 86
