PCA alleviated the impaired EDR and ROS overproduction in C57BL/6J mouse aortas treated with IL-1β. Summarized data (A) of EDR and endothelium-independent relaxation (B) measured by wire myograph in IL-1β-treated aortas from male C57BL/6J mice incubated with and without PCA (10 – 100 nM); n = 5. Representative confocal images (C) and summarized data (D) of DHE stain intensity in aortic rings from C57BL/6J mice with and without PCA incubation (10- 100 nM); n = 6-7. Data are presented in means ± SEM; **p < 0.01. PCA, protocatechuic acid; Phe, phenylephrine; ACh, acetylcholine; SNP, sodium nitroprusside; DHE, dihydroethidium.
