Effect of Curcumine on Expression of Matrix Metalloproteinase- 9 in Human Umbilical Vein Endothelial Cell / 中药新药与临床药理

ABSTRACT

Objective To investigate the effect of curcumine on the expression of matrix metalloproteinase-9 (MMP-9) in human umbilical vein endothelial cell (HUVEC). Methods HUVEC were cultured and identified in vitro .After cultured with curcumine at different concentration for 24 hours, the expression of MMP-9 in HUVEC was detected by cytoimmunochemical staining method and ELISA . Results All concentrations of curcumine can restrain the expression of HUVEC after co- culturing with the cells for 24 hours. The inhibitory effect got stronger with the increase of the concentration of curcumine. Conclusion The curcumine can depress the expression of matrix metalloproteinase-9 in HUVEC obviously.
