Article Title: Sodium propionate alleviates bronchopulmonary dysplasia by inhibiting ferroptosis through the SLC7A11/GPX4 pathway in pulmonary endothelial cells

doi: 10.1186/s12931-026-03535-3

Figure Lengend Snippet: A proposed mechanistic model illustrating how SP alleviates BPD. In HUVECs, hyperoxia exposure suppresses the SLC7A11/GPX4 antioxidant axis, leading to increased lipid peroxidation (LPO) and reactive oxygen species (ROS), thereby triggering ferroptosis. Concurrently, the expression of pro-angiogenic factors (VEGFA, CD31) is downregulated, resulting in impaired vascular development and alveolar simplification—the hallmark pathological features of BPD. SP treatment counteracts hyperoxia-induced damage by upregulating the SLC7A11/GPX4 pathway. The activation of this axis inhibits ferroptosis (reducing LPO and ROS) and restores the expression of VEGFA and CD31, thereby promoting angiogenesis and preserving alveolar structure. This model summarizes the core finding: SP exerts protective effects against BPD by modulating ferroptosis and vascular development through the SLC7A11/GPX4 signaling axis

The cells were treated with baicalein and docetaxel individually or in combination for 24 hours. The expression of vascular endothelial growth factor (VEGF), transforming growth factor β1 (TGF-β1) (A), E-cadherin, and N-cadherin (D) proteins were measured by Western blotting analysis. The histogram (B, C, E, F) was presented as the mean±SEM of the band density for three independent experiments compared with β-actin expression. aP<0.01; bP<0.001 vs. baicalein alone and docetaxel combined treatment.
