Fig. 2From: Rhodiola crenulata extract counteracts the effect of hypobaric hypoxia in rat heart via redirection of the nitric oxide and arginase 1 pathwayEffect of RCE on cardiac eNOS expression and downstream effectors. The expression of eNOS was analyzed by western blotting (a). The content of nitrite (c) and cGMP (d) was assayed by the commercial kits. A quantitative analysis of eNOS expression level was conducted (b). The results represent the mean ± SEM (n = 3). *p < 0.05 and ***p < 0.001 vs. the sample without RCE. #p < 0.05, ##p < 0.01, and ###p < 0.01 vs. hypoxia (H)Back to article page
