Figure Lengend Snippet: RTEF-1 as a target gene of miR-125a-5p in H-EXO alleviating hypoxia-induced vascular endothelial cell dysfunction. (A) Representative images of in vitro wound healing assay results. (B) Statistical analysis of in vitro wound healing. (C) Lower chamber fluorescence over time in permeability experiments. (D), (E) DCFH-DA staining fluorescence was used to detect intracellular ROS production and statistical analysis. (F), (G) Expression and statistical analysis of RTEF-1, VEGF, P2Y12, and INOS were investigated by WB. (H) Correlation between RTEF-1 and VEGF expression in GSE122952 dataset. All data are presented as mean ± SD, statistical analysis using one-way analysis of variance. ∗ P < 0.05, ∗∗ P < 0.01, ∗ versus Hypo group, # versus Si-RTEF-1-Sham group. Scale bars: 200 μm (B), 50 μm (E).
