Alterations of gene expressions in proximal intestine by oral Glu intake. Relative expression of genes related to nucleic acid synthesis in proximal intestine. a cps2: carbamoyl-phosphate synthetase, b ppat: phosphoribosyl pyrophosphate amidotransferase, c pfas: phosphoribosylformylglycinamidine synthase. The tissues were collected before (initial), 30, 120, and 360 min after administration of 50 or 500 mg/kg Glu. The expression of the genes were estimated by quantitative RT-PCR and normalized by arbp. All values are expressed as the mean ± SEM (n = 6). *p < 0.05 as compared to initial group
