PCA decreased the IL-1β-stimulated ROS and pro-inflammatory cytokine levels in endothelial cells. Representative confocal images (A) and summarized data (B) of DHE stain intensity in mBMECs with and without PCA incubation (1-100 nM); n = 3. Summarized quantification of mRNA levels of VCAM1 (C), ICAM1 (D), MCP1 (E), iNOS (F), eNOS (G) and UCP1 (H) relative to 36B4 in mBMECs with and without IL-1β (0.5 ng/mL) and PCA (1–100 nM) incubation; n = 6–7. Data are presented in means ± SEM; *p < 0.05, **p < 0.01. PCA, protocatechuic acid.
