Alterations of gene expressions in distal intestine by 8 weeks of Glu supplementation in feed. Relative expression of genes related to nucleic acid synthesis in distal intestine. A cps2: carbamoyl-phosphate synthetase, B ppat: phosphoribosyl pyrophosphate amidotransferase, C pfas: phosphoribosylformylglycinamidine synthase. The fishes were challenged to 8 weeks of experiment. The tissues were collected after the 48 h-fasting. The expression of the genes were estimated by quantitative RT-PCR and normalized by arbp. All values are expressed as the mean ± SEM (n = 8). Different letters indicate significant difference between groups (p < 0.05)
