Various tissue weights corrected by body weight of control (WT mice fed the 0.17% L-Trp diet) and Tdo^−/− mice fed the 0.17% L-Trp diet, 0.08% L-Trp diet and 0.06% L-Trp diet.

	Control	Tdo−/− mice
		0.17% L-Trp	0.08% L-Trp	0.06% L-Trp
Liver (g/100 g body weight)	4.98 ± 0.25	4.60 ± 0.07	4.68 ± 0.13	4.52 ± 0.17
Small intestine (g/100 g body weight)	2.92 ± 0.10	3.35 ± 0.17	2.79 ± 0.20	3.00 ± 0.14
Hippocampus (mg/100 g body weight)	122 ± 5	111 ± 4	107 ± 2	115 ± 4
Striatum (mg/100 g body weight)	89.2 ± 11.2	88.5 ± 2.6	92.9 ± 7.3	70.2 ± 5.5
Cerebral cortex (mg/100 g body weight)	665 ± 25	655 ± 27	603 ± 25	657 ± 25

Notes: Values are the mean ± SEM, n = 3–5. Statistical analysis was determined by one-way ANOVA and was followed by Tukey’s multiple-comparison test. But, all means did not observed significant differences.
