PP2A inhibition acutely exacerbates insulin resistance in chow- and fat-fed rats. LB1-treated rats required a reduced glucose infusion rate to maintain euglycemia during the hyperinsulinemic-euglycemic clamp (a). This was not associated with changes in hepatic glucose output (b), but was the result of an impaired glucose turnover rate (c). Muscle insulin sensitivity was not altered as assessed by 2-deoxyglucose uptake (2-DOG) (d), however LB1-treatment was associated with an increase in insulin-stimulated glucose uptake in white adipose tissue (e). Data are averages ±SEM. * P<0.05.
