GAL and bronchopulmonary dysplasia: Genes predicting BPD are significantly overrepresented in inflammatory and Galanin/GMAP prepropeptide pathways (Supplementary Table 3) and increased disease severity is characterized by the regulation of immune and defense response pathways (Supplementary Table 4) including activated chemotaxis of cells, increased biological functions associated with apoptosis, accumulation of leukocytes, and decreased phagocytosis by immune cells (Supplementary Table 5).
