mRNA quantification of the indicated chemokines relative to G6pdx expression. BMDC were pretreated for 60 min with 500 nM cEC or the variant BisRed prior to R837 stimulation (5 μg/ml) for 3 h. Data (mean ± SD) are representative of three independent experiments. *P < 0.05; **P < 0.01; unpaired two-tailed t-test.
