Abstract Melatonin is secreted by the pineal gland and gastrointestinal tract and plays a role in circadian rhythm synchronization. Melatonin is also reported to have various physiological effects on endothelial cells. Endothelial cells are responsible for physiologic homeostasis and maintaining blood vessel permeability in vivo. In this study, using gene expression profiling, we confirmed about 151 up regulation and 1,023 downregulation expression genes, with an expression level difference of 짚1.5-fold, after exposure to 100 關M and 1 mM melatonin concentrations in endothelial cells. The genes were classified into 16 functional groups based on their functions, including cell adhesion, immune response, lipid metabolism, and response to stress. We analyzed the gene expression profiling data of melatonin-treated human umbilical vein endothelial cell(HUVECs), which indicated a broad spectrum of physiological functions, including anti-oxidative/anti-inflammatory effects and cell-to-cell junction maintenancerelated genes.
