Hepatic insulin resistance is a hallmark of type 2 diabetes. I conducted quantitative proteomic profiling of liver tissue in a high fat diet (HFD) mouse model of hepatic insulin resistance. The epoxyeicosatrienoic acid (EET) pathway emerged as a candidate for functional validation, as its repression coincided with hepatic insulin resistance. I showed that EETs enhance insulin signaling in hepatocytes at the level of its central protein kinase, Akt. These results imply that HFD may contribute to hepatic insulin resistance by repressing the synthesis of positive modulators of insulin signaling.
