ABSTRACT
AIM:
To investigate the effects of oxysterols on matrix metalloproteinase (MMP) and tissue inhibitor of metalloproteinase-1 (TIMP-1) expression in vascular smooth muscle cells.METHODS:
Rabbit aortic vascular smooth muscle cells were cultured in vitro and incubated with cholesterol, Triol and 25-hydroxycholesterol (25-OH), respectively. Slot blot was used to detect the mRNA expression level of TIMP-1 in vascular smooth muscle cells (VSMCs); meanwhile the protein expression level of MMP-9 and TIMP-1 was detected by immunohistology.RESULTS:
Triol and 25-OH inhibited the expression of TIMP-1 compared with control and cholesterol, but have no effect on expression of MMP-9.CONCLUSION:
Both Triol and 25-OH downregulated TIMP-1 expression in VSMCs .
