Cxcl1, Cxcl3, Cxcl13, Itgam, Lyz2, Lgals3 encode for cytokines that are known to be dysregulated in animal models of hyperoxia-induced BPD (Deng et al., 2000; Rudloff et al., 2017; Hurskainen et al., 2021; Dong et al., 2022), and Trem1 is a protein-coding gene encoding for Triggering Receptor Expressed on Myeloid Cells 1 (TREM1) which is upregulated in preterm infants who developed BPD (Ambalavanan et al., 2009). Here, ITGAM is linked to bronchopulmonary dysplasia.
