Effect of simulated altitude at 5500 m on HPT axis and HPA axis hormones. Serum levels of CRH (a), ACTH (b), CORT (c), TRH (d), tT4 (e). Data were expressed as mean ± SEM. n = 6/group. ∗∗p < 0.01, ∗∗∗p < 0.001, ∗∗∗∗p < 0.0001 compared to control group using two-tailed unpaired t-tests. CRH corticotropin-releasing hormone, ACTH adrenocorticotropic hormone, CORT corticosterone, TRH thyrotropin-releasing hormone, tT4 thyroxine.
