The basal mRNA expression (Figure 6) of IL-6 (Figure 6A), MCP-1 (Figure 6B), CINC1 (Figure 6C), PAI-1 (Figure 6D), tissue factor (TF; Figure 6E), and Heme Oxygenase 1 (HMOX1; Figure 6F) was comparable in Wistar rats with and without BPD and in LPAR1-deficient rats with BPD except for IL-6. This evidence concerns the gene HMOX1 and bronchopulmonary dysplasia.
