AngII and IL-1β differentially regulate mPGES-1, PGIS and TXAS expressions. Effect of AngII, IL-1β or AngII + IL-1β (24 h) on mPGES-1, PGIS and TXAS mRNA levels (A, C, E) and protein expression (B, D, F) in rat VSMC. Data are expressed as mean ± SEM. *P < 0.05, **P < 0.01, ***P < 0.001 versus control; †P < 0.05 versus AngII and IL-1β. n = 5–8.
