Abstract

During many pathological conditions, the tryptophan concentration in blood may be reduced. However, the effects of oxidative stress on tryptophan metabolism remain unknown. In this study, we investigated the effects of oxidative stress on growth performance and tryptophan metabolism in weaned pigs. A total of 24 weaned pigs were assigned to one of three treatments that included pigs fed ad libitum (control), pigs challenged with diquat at a dose of 10 mg/kg BW and fed ad libitum (oxidative stress) or pigs pair-fed to receive the same amount of feed as the diquat-challenged pigs. The trial lasted for 7 days. The growth performance and activities of antioxidant enzymes were declined in diquat-challenged pigs. The diquat challenge decreased the tryptophan concentration in serum and the 5-hydroxytryptamine concentration in the hypothalamus, and increased large neutral amino acids, kynurenine (Kyn) and malondialdehyde in serum. The 544-bp porcine partial mRNA sequence of the tryptophan 2,3-dioxygenase (TDO) gene was obtained according to the conserved region in the human gene sequence. In addition, the oxidative stress induced by the diquat challenge stimulated TDO-relative mRNA abundance in the liver and γ-glutamyl transpeptidase activity in intestinal mucosa, but did not affect the mRNA levels of Na+-neutral amino acid transporter B0. These results suggested that oxidative stress induced by diquat depressed growth performance and increased metabolism of tryptophan via Kyn pathway that upregulated TDO mRNA expression in weaned pigs.
