Abstract:
Objective To explore the effect of IL-1? and IL-6 on MMP-3 gene expression in human coronary artery smooth muscle cells.Methods We used IL-1?(20 ?g/L) and IL-6(10 ?g/L) to stimulate human coronary artery smooth muscle cells,which were co-culture for 0,2,4,8,24,36 h.IL-1?(0,5,20,40 ?g/L) and IL-6(0,5,10,50 ?g/L) were used to stimulate human coronary artery smooth muscle cells,which were co-cultured for 6 h.Then we detected the gene expression by fluorescent quantitation PCR.Results In the same concentration of IL-1? and IL-6,gene expression was up-regulated at 2 h,at 8 h the expression reached the peak,then began to descend.In different concentration of IL-1? and IL-6,gene expression was up-regulated with the dose of IL-1? and IL-6(IL-1?: r=0.907,P=0.000;IL-6: r=0.919,P=0.000).There were significant differences in MMP-3 expression among different groups(IL-1?: F=24.047,P=0.000;IL-6: F=14.081,P=0.001).There were no significant differences in matrix metalloproteinase-3 between IL-1? 20 and 40 ?g/L groups(P=0.154) and between IL-6 5 ?g/L and 10 ?g/L(P=0.292).Conclusion It suggests that IL-1? and IL-6 can promote MMP-3 gene expression in human coronary artery smooth muscle cells,and it may be one of the mechanisms of inflammation effect in acute coronary syndrome.
