Abstract
We investigated the effect of cardiac-targeting erythropoietin (EPO)-encapsulated liposomes with sialyl LewisX (SLX) on myocardial infarct (MI) size, left ventricular (LV) remodeling and function, and its molecular mechanism for repairing infarcted myocardium. In rabbits, MI was induced by 30 min of coronary occlusion followed by reperfusion. EPO-encapsulated liposomes with SLX (L-EPO group), EPO-encapsulated liposomes without SLX (L-EPO without SLX group), liposomes with SLX without EPO (L group), or saline (saline group) were intravenously administered immediately after MI. MI sizes and numbers of microvessels were assessed 14 days after MI. Prosurvival proteins and signals were assessed by Western blot analysis 2 and 14 days after MI. Confocal microscopy and electron microscopy showed the specific accumulation of liposomes with SLX in the infarcted myocardium. MI and cardiac fibrosis areas were significantly smaller in the L-EPO group than in the other groups. LV function and remodeling were improved in the L-EPO group. The number of CD31-positive microvessels was significantly greater in the L-EPO group than in the other groups. Higher expressions of EPO receptors, phosphorylated (p)Akt, pERK, pStat3, VEGF, Bcl-2, and promatrix metalloproteinase-1 were observed in the infarct area in the L-EPO group than in the other groups. EPO-encapsulated liposomes with SLX selectively accumulated in the infarct area, reduced MI size, and improved LV remodeling and function through activation of prosurvival signals and by exerting antifibrotic and angiogenic effects. EPO-encapsulated liposomes with SLX may be a promising strategy for active targeting treatment of acute MI.
