In alveolar epithelial cells from mice with bronchopulmonary dysplasia, inhibition of YTHDC1 led to a decrease in IL-33 mRNA and protein expression, which in turn inhibited alveolar epithelial cell apoptosis and alleviated lung injury induced by hyperoxia treatment for bronchopulmonary dysplasia (Bao et al., 2023). The gene discussed is YTHDC1; the disease is bronchopulmonary dysplasia.
