Replacing dietary glucose with fructose increases ChREBP activity and SREBP-1 protein in rat liver nucleus

Diets high in fructose cause hypertriglyceridemia and insulin resistance in part due to simultaneous induction of gluconeogenic and lipogenic genes in liver. We investigated the mechanism underlying the unique pattern of gene induction by dietary fructose. Male Sprague–Dawley rats (n = 6 per group) were meal-fed (4 h/d) either 63% (w/w) glucose or 63% fructose diet. After two weeks, animals were killed at the end of the last meal. Nuclear...
