Core Tip
Core tip: Nonalcoholic fatty liver disease (NAFLD) associated with obesity, insulin resistance, and type 2 diabetes, is an increasingly recognized trigger of hepatocellular carcinoma (HCC), even in non-cirrhotic livers. The role of inherited factors seems magnified in fatty liver. The common I148M variant of the PNPLA3 gene influencing hepatic lipid metabolism has been associated with HCC. Rare loss-of-function mutations in apolipoprotein B resulting in very low density lipoproteins hepatic retention and in telomerase reverse transcriptase influencing senescence have been linked to HCC in NAFLD. Hepatic stellate cells senescence has also been suggested to bridge tissue aging with microbiota alterations in the pathogenesis of obesity-related HCC.
