doi: 10.1080/13510002.2025.2494314
Figure Lengend Snippet: Effects of α- and β-adrenoceptor antagonists on NE-induced oxidative stress in VAFs of WKY and SHR. NE (20 μM) was administered 1 h after the application of α-receptor antagonist prazosin (10 μM) or β-receptor antagonist propranolol (3 μM). Measurements were made 4 h after the application of NE. (a) superoxide level. (b) bar graph showing the relative DHE fluorescence intensity. (c) representative images showing DHE fluorescent staining (red) of VAFs. Nuclei were stained with Hoechst33342 (blue). (d) NOX activity. (e) NOX2 protein expression. (f) representative images showing the NOX2 protein expressions. Values are mean ± SD. Two-way ANOVA followed by Bonferroni post hoc test. * P < 0.05 vs Ctrl; † P < 0.05 vs PBS; # P < 0.05 vs WKY. n = 6 in (a–d); n = 4 in e.
