Differential expression results for all comparison groups corresponding to four cytokine genes that were selected for further study.

Genes were selected based on being (1) members of the GO:0008009~chemokine activity ontological category, which was significantly over-represented among genes differentially expressed in response to vitamin D treatment in both fatal asthma- and non-asthma-derived ASM, that were (2) differentially expressed in fatal asthma-derived vs. non-asthma-derived ASM at baseline. FPKM = fragments per kilobase of transcript per million mapped reads.
