After 12 hours of culture without FCS, rheumatoid arthritis fibroblast-like synoviocytes were stimulated for 20 min with individual or combined cytokines at low concentrations: IL-1 (10 pg/ml), TNF-α (10 pg/ml) and IL-17 (50 ng/ml). Cells were lyzed and total mRNA was extracted. RT-PCR was performed as described in Materials and methods. The intensity of the respective and c-bands was measured by densitometry. Results were expressed as the ratio between c-values divided by those of the internal control and were the mean of three independent experiments. CT, control.
