The gene targets of the two developmental miRNAs that were differentially expressed by IUS exposure during human fetal lung development include genes that have been previously associated with asthma susceptibility in published genome-wide association studies (GWAS) of asthma, including an association of miR-15a with Gasdermin B (GSDMB) [27] and miR-155 with thymic stromal lymphopoietin (TSLP) [28] (Table 4). The gene discussed is GSDMB; the disease is asthma.
