Quantitative proteomics links mitochondrial dysfunction to metabolic changes and epithelial differentiation defects in hyperoxia-exposed neonatal airway cells
We report that moderate hyperoxia during a critical window of mucociliary differentiation disrupts terminal maturation in neonatal airway epithelial cells cultured in a three-dimensional model. Hyperoxia induces mitochondrial bioenergetic dysfunction and metabolic reprogramming, with proteomic analysis identifying complex I disruption as a key driver of impaired differentiation. Overall, these findings reveal a previously underrecognized link between mitochondrial bioenergetics and airway epithelial development, positioning metabolic dysfunction as an early trigger of hyperoxia-induced neonatal airway injury.
