Modulation of cytokine mRNA and protein expression in macrophages from wildtype controls (WT) and COX-2-deficient mice (KO). Primary Kupffer cells (KC), peritoneal macrophages (PM) and bone marrow-derived macrophages (BMDM) were stimulated for 24 h with LPS. Relative mRNA expression of TNF-α (A) and OSM (C) were determined by RT-qPCR with Hprt as the reference gene. (B) TNF-α protein levels were determined by ELISA in cell culture supernatants. Values are median (line), upper- and lower quartile (box) and extremes (whiskers) of n = 26–32 (WT) or n = 5–10 (KO) independent experiments. Statistics: Two-way-ANOVA with Tukey´s post hoc test for multiple comparison. *p < 0.05
