Fig. 3From: Effect of water-immersion restraint stress on tryptophan catabolism through the kynurenine pathway in rat tissuesLevels of TDO and IDO1 mRNA expression in liver tissues of rats subjected (+) or not (−) to 6 h of WIRS based on assays of TDO and IDO1 described in the Materials and methods. Each value is the mean ± SD (n = 7 −WIRS rats; n = 8 +WIRS rats). *P < 0.05 (vs. −WIRS rats)Back to article page
