PCA inhibited MCP1 but promoted p-eNOS/eNOS and p-Akt/Akt protein expressions in IL-1β-treated endothelial cells. Summarized protein quantification of (A) MCP1, (B) p-eNOS/eNOS and (C) p-Akt/Akt relative to GAPDH with and without IL-1β (0.5 ng/mL) and PCA (1-100 nM) incubation with representative immunoblots (D); n = 6-7. P-eNOS, eNOS, 140 kDa; p-Akt, Akt, 60 kDa; MCP1, 25 kDa; GAPDH, 37 kDa. Data are presented in means ± SEM; *p < 0.05. PCA, protocatechuic acid.
