Effect of RCE on cardiac arginase expression and activity. After hypobaric hypoxia exposure (8000 m) for 9 h, the expression level of Arg-1 and arginase activity were analyzed by western blotting (a) and a commercial kit (b), respectively. A quantitative analysis of the Arg-1 expression level was conducted (c). The results represent the mean ± SEM (n = 3). *p < 0.05 and **p < 0.01 vs. the sample without RCE. #p < 0.05 and ##p < 0.01 versus hypoxia (H)
