Fructose promotes liver cancer via microbial acetate-induced O-GlcNAcylation

High dietary fructose consumption is linked to multiple disease states, including cancer. Zhou and colleagues recently reported a novel mechanism where high dietary fructose levels increase acetate production by the gut microbiome increasing post-translational modification O-GlcNAcylation in liver cells, which contributes to disease progression in mouse models of hepatocellular carcinoma.
