(A) Wild type mice (open bars) and Pctp−/− mice (solid bars) were fed 7 d with a fenofibrate supplemented diet (wild type, n = 8; Pctp−/−, n = 6) prior to measuring plasma concentrations of (A) glucose and (B) insulin. The same mice (wild type, ○; Pctp−/−, ●) were then subjected to (C) glucose and (D) insulin tolerance tests. Inserts provide AUC values (wild type, open bars; Pctp−/−, closed bars). *P < 0.05, wild type vs. Pctp−/− mice.
