Figure 3 Location of lectin-like oxidized low-density lipoprotein receptor (LOX-1) expression in rat cardiac myocytes was confirmed by double immunostaining (brown color = LOX-1; red color = anti-desmin for rat cardiac myocytes); LOX-1 expression was primarily within the cardiac myocytes. Left panel is a negative control specimen, middle panel is myocyte staining in sham control heart, and right panel is double staining showing LOX-1 expression in myocytes. I-R = ischemia-reperfusion.
