Liver cancer is a major public health issue and generally considered an inflammation-related cancer developing in response to genotoxic exposure or in patients with viral, alcoholic or non-alcoholic hepatitis. It is a leading cause of cancer-related deaths worldwide, with hepatocellular carcinoma (HCC) representing 90% of primary liver cancer cases. Various pathways are dysregulated in HCC, including p53 and other cell cycle regulators, chromatin modifiers, oxidative stress, insulin and growth factor signalling, and Wnt/β-catenin signalling. In this issue, Senni and colleagues1 demonstrate the role of fatty acid oxidation as a source of energy in the metabolic adaptation triggered by β-catenin oncogenic activation in hepatocytes. This work describes an atypical cancer cell addiction to fatty acids and represents an important discovery that may pave the way for novel therapeutics.
The Wnt/β-catenin pathway2 plays a key role in many aspects of hepatic homeostasis, including the regulation of unique liver features,...
