Long-term administration of recombinant canstatin prevents adverse cardiac remodeling after myocardial infarction.

ABSTRACT: Myocardial infarction (MI) still remains a leading cause of mortality throughout the world. An adverse cardiac remodeling, such as hypertrophy and fibrosis, in non-infarcted area leads to uncompensated heart failure with cardiac dysfunction. We previously demonstrated that canstatin, a C-terminus fragment of type IV collagen α2 chain, exerted anti-remodeling effect against isoproterenol-induced cardiac hypertrophy model rats. In the present study, we examined whether a long-term administration of recombinant canstatin exhibits a cardioprotective effect against the adverse cardiac remodeling in MI model rats. Left anterior descending artery of male Wistar rats was ligated and recombinant mouse canstatin (20 μg/kg/day) was intraperitoneally injected for 28 days. Long-term administration of c
