Differences in intestinal lipids and secretion. A: Intestinal profiles of TAG, DAG, FFAs (FA), total cholesterol (CH), and total phospholipids (PL) 30 min and (B) 60 min after the [³H]TO-containing fat load. C: Plasma lipid profiles 180 min after the [³H]TO lipid load. Pcyt2^+/− and Pcyt2^+/+ (n = 5). The values shown in A and B are dpm/mg of protein for intestinal mucosa and in C are dpm/ml for mouse plasma at P < 0.05. D: Intestinal mucosa TAG (µmol/kg) is elevated 1.8-fold in Pcyt2^+/− mice relative to the wild-type mice (40 wk-old; n = 4 and P < 0.0001). E: Iodine-stained silica gel showing relative increases in DAG and TAG levels (2.3-fold and 1.9-fold, respectively) in the samples as in D.
