D CUEDC2 protein level was plotted using the immunohistochemical scores as described in methods. (left) Plot of CUEDC2 scores in each BZ and DZ (n = 9 patients). (right) Representative images from immunohistochemistry staining for CUEDC2 in tissues from patients who suffered acute myocardial infarctions. The boxed areas in the left images are magnified in the middle and right images. DZ, distant zone; BZ, border zone. Scale bars, 250 μm (left), 50 μm (middle and right). * p = 0.001.
