Highlights
• Glycidol at sublethal concentrations triggered endothelial-to-mesenchymal transition in HUVECs.
• Glycidol at cytotoxic doses induced apoptosis and inflammation in HUVECs.
• Glycidol activated the NF-κB/MAPK signaling possibly mediated by oxidative stress
• 6-C-(E-fluorostyryl)naringenin alleviated glycidol-induced endothelial injuries.
