The OA-NO2-induced downregulation of lp-PLA2 occurs via a PPARγ-independent mechanism.
THP-1 cells were incubated with OA-NO2, Rosiglitazone and GW9662 at the indicated concentrations for 1 h and then stimulated with PMA (0.05 μM). (A and C), The relative Lp-PLA2 mRNA expression levels were determined after stimulation with PMA for 12 h. (B), The activation of PPARγ and Lp-PLA2 protein expression levels were determined after stimulation with PMA for 24 h.
