Adenoviral-mediated (AdV-T2) overexpression of TIMP-2 would blunt ventricular remodeling and improve survival in a murine model of chronic ischemic injury. Male mice (n=124) aged 10–14 weeks underwent either 1) left coronary artery ligation to induce myocardial infarction (MI group, n=36), 2) myocardial injection of 6×1010 viral particles of AdV-T2 immediately post-MI (MI+T2 group, n=30), 3) myocardial injection of 6×1010 viral particles of a control adenovirus (MI+Ct, n=38), or 4) received no intervention (controls, n=20). On post-MI day 7, surviving mice (n=79) underwent echocardiographic, immunohistochemical and biochemical analysis. In infarcted animals, the MI+T2 group demonstrated improved survival (p< 0.02), better preservation of developed pressure and ventricular diameter (p<0.04), and the lowest expression and activity of MMP-2 and MMP-9 (P<0.04) compared with MI and MI+Ct groups.. All infarcted hearts displayed significantly increased inflammatory cell infiltration (p<0.04 versus control, MI, or MI+T2), with infiltration highest in the MI+Ct group and lowest in the MI+T2 group (p<0.04). Adenoviral mediated myocardial delivery of the TIMP-2 gene improves post-MI survival and limits adverse remodeling in a murine model of myocardial infarction.
