Abstract:

BACKGROUND: The effective treatment of traditional Chinese medicine can alleviate the aging of endothelial cells. Traditional Chinese medicine is difficult to extract, and in contrast, Bergapten is cheap and easily purified, but its antisenescence is little reported.
OBJECTIVE: To explore the effect of Bergapten on H2O2-induced senescence of human umbilical vein endothelial cells.
METHODS: Human umbilical vein cell aging model was induced by H2O2, and pretreated with 0.1, 1 and 10 μmol/L Bergapten, respectively. Expressions of pRb, pAmpk, pS6, LC3-II, and Beclin-1 protein in each group were detected by western blot assay, and the number of aging cells and pS6-positive cells was determined by β-galactosidase staining and immunofluorescence, respectively.
ESULTS AND CONCLUSION: After Bergapten pretreatment, pS6 and pRb protein expressions were significantly downregulated, and the number of cells positive for β-galactosidase and pS6 was significantly decreased, while protein expressions of pAmpk, Beclin-1and LC3-II were significantly increased (P < 0.05). These findings suggest that Bergapten is able to delay the H2O2-induced aging of human umbilical vein endothelial cells
