E mRNA expression of the indicated chemokines as determined by qPCR. Wild-type BMDCs were treated with EC (1 μM) or 15d-PGJ2 (20 μM) for 60 min followed by R837 stimulation (5 μg/ml) for 3 h. Expression levels are shown normalized to G6pdx. Data (mean ± SEM, n = 2) are representative of three independent experiments.
