NOD1 and asthma: In terms of bio-ontologic enrichment, the 19 asthma genes consistently differentially expressed in human and mouse lung development were enriched for ontological attributes "Regulation of cytokine production" (IRAK3, CD86, NOD1, TNF, IL18, SCGB1A1) and "Regulation of cell activation" (STAT6, CD86, IL18, IL4R, RORA, SCGB1A1) (Additional file  1, Table E4).
