Objective To investigate the function of TIMP-3 in the development of graft arteriosclerosis after orthotopic transplantation.Methods SD-Wistar abdominal aorta transplantation was performed in 60 pairs,30 pairs of which received the exogenous TIMP-3 transfection into transplanted vessels.Wistar-Wistar abdominal aorta transplantation was performed in 30 pairs.The expressions of MMP-1,2 and TIMP-3 in the tissues of transplanted abdominal aorta were measured by immunohistochemical method,the expression of MMP-2 was detected by Northern blot quantitative analysis and the activity of MMP-2 was observed by photo analysis on 3rd day,1st,2nd,4th,8th week after transplantation.Results The expressions of MMPs,TIMP-3 in the allograft group were higher than the isograft group.The expressions of TIMP-3 on 1st and 2nd week [(1.7±1.1) and(0.9±0.4)] in the allografts with exogenous TIMP-3 gene transfection were much higher than those of allografts and isografts(P0.05),but the activity of MMP-2 was opposite.Conclusion While the exogenous TIMP-3 gene was admitted on early stage of CR,intervening the balance between MMPs and TIMPs,decreasing the expression and activity of MMPs,and reducing the formation of ECM can slacken CR efficiently.
