SMCs were treated with 100 ng/ml IL-17 for 6 h in three independent experiments using different donors. The mean fold change of cytokine and chemokine transcript expression in response to IL-17 treatment was assessed by microarray (certain cytokines were represented by more than one probe) and quantitative RT-PCR (qPCR). Transcripts for which IL-17–mediated up-regulation was not diminished by 10 μg/ml cycloheximide, as assessed by RT-PCR, were considered primary gene targets.
