a–d Acetylcholine assay of mouse (3, 5, 8, 15, 22 and 30 weeks old), domestic cat (3, 6, 12 and 36 months old), rat (3, 8, 15, 30 and 50 weeks old) and Siberian tiger (6 years old) pituitary gland by UPLC-MS [domestic cat (n = 3), mouse (n = 6), rat (n = 6) and Siberian tiger (n = 1)]. The concentration of acetylcholine in the adult Siberian tiger pituitary is approximately 2.4 µM. e Schematic diagram of regulation hypothesized mechanism contributing to body size of Siberian tiger. All statistical data are given as average ± SEM.
