DLL4 and asthma: Possible empirical mRNA targets for each of these miRNAs, measured by pairwise correlation to fetal lung microarray data, are provided in Table 2 and include genes critical to both lung development (e.g., angiogenesis genes VEGFC, DLL4) and asthma and allergy (CXCL16, ORDML3, IL4R, ILF3).
