A potential unifying factor upstream of these genes is the cannabinoid‐1 receptor, stimulation of which was found to upregulate several of the above‐listed target proteins, including Fasn, Pklr, Pnpla3, and Pcsk9 in mouse models of obesity/metabolic syndrome and HCC, as documented and detailed. This evidence concerns the gene PCSK9 and hepatocellular carcinoma.
