CDC42EP3 and asthma: A subset of these genes (i.e., CDC42EP3, ITPR1, G6PD) was differentially expressed in the fatal asthma- vs. non-asthma-derived ASM at baseline comparison, while a different subset (i.e., CEBPB, CDC42EP3, ITPR1, and HSD11B1) was differentially expressed in fatal asthma-derived ASM when stimulated with vitamin D vs. left untreated [S7 Table].
