Fig 1: Protein expression of MAS1 and p-eNOS was similar in the 3 experimental groups. The protein expression levels of MAS-1 and p-eNOS in the 3 experimental groups were examined by immunofluorescence staining. The target proteins were stained with fluorescein isothiocyanate (green). No statistical differences in the expression levels of MAS1 and p-eNOS among the 3 groups were identified. Scale bar=100 µm. Data were represented as the mean ± standard error of the mean (n=3 wells/group). SX, Suxiao Jiuxin Pill; IOD, integrated optical density; eNOS, endothelial nitric oxide synthase; p-, phosphorylated.
