螺内脂降低大鼠心肌非梗死区MMP/TIMP基因转录及表达
Spirolactone decreases transcription and expression of MMPs/TIMP-2 gene in myocardial noninfarct area of rat
摘要
Abstract
Objective To investigate the effects of the aldosterone receptor antagonism spironolactone on the relationship between MMPs/TIMPs expression and activity remodeling after myocardial infraction (MI) and to explore the molecular mechanism of heart failure prevention after MI. Methods Myocardial infarction model was set up by drug intervention. Histopathology was detected by HE staining. Immunohistochemical and RT-PCR were used to observe the gene and protein expression of MMP-2, MMP-9, TIMP-2. Results Post infarction both compare MI and control MMP-2, MMP-9, TIMP-2 was significantly increased in 48 h and then remains at higher level for 4 weeks (P <0. 01). MMP-2 and MMP-9 patency fallout, TIMP-2 no-apparent fallout by spirolactone interference. Conclusions Spirolactone can decrease transcription and expression of MMP-2, MMP-9/TIMP-2 activity in myocardial noninfarct area of rat.关键词
