Figure 8. — Expression of MMP‐9. Total LV lysates, prepared from sham, non‐infarct (Non) and infarct (Inf) LV regions 1 and 3 day post‐MI, were analyzed by Western blot using anti‐MMP‐9 antibodies. The upper panels depict autoradiograms indicating immunostaining for MMP‐9 and GAPDH. The lower panels exhibit quantitative analyses of MMP‐9 normalized to GAPDH. A, MMP‐9 protein levels 1 day post‐MI (n=6). B, MMP‐9 protein levels 3 days post‐MI (n=5) ^#P<0.05 vs sham. hKO indicates heterozygous knockout; Inf, infarct; LV, left ventricle; MI, myocardial infarction; MMP, matrix metalloproteinase; WT, wild‐type.
