In hypoxia-induced pulmonary fibrosis, a study (Xu, 2022) has been found that in pulmonary fibrosis tissues as well as cells, lncRNA-NEAT1 is highly expressed, which promotes the apoptosis of alveolar epithelial cells and upregulates the expression of pulmonary fibrosis index protein, while miR-29a is lowly expressed. The gene discussed is NEAT1; the disease is pulmonary fibrosis.
