FGF10 and bronchopulmonary dysplasia: – Specific microRNAs (e.g., miR-21, miR-34a, miR-431) are differentially expressed in BPD. – miR-17∼92 cluster downregulation correlates with BPD severity. – Elevated levels of miR-421 target FGF10, exacerbating inflammation and apoptosis in BPD. – miR-29b administration may enhance lung phenotype in severe BPD models.
