At 1 h, 3 h, 6 h, 12 h, 24 h, 3 d, 5 d after MI, the relative expression level of Mipu1 mRNA in the infarct zone was, respectively, 1.2-, 2.5- (P < 0.05), 6.3- (P < 0.05), 5.4- (P < 0.05), 1.9-, 1.7-, 1.5-fold greater than that in sham operated hearts. This evidence concerns the gene ZNF667 and myocardial infarction.
