Here, we further demonstrated in 145E mice that hyperphagia, hyperglycemia, hyperinsulinemia, insulin resistance, dyslipidemia, hepatic steatosis, and adiposity were all accompanied by elevated cytokine expressions and lowered phosphorylation of Akt, STAT3, and STAT6 in the hypothalamus, liver, and epididymal fat. The gene discussed is STAT3; the disease is hyperinsulinism.
