Heatmap of miRNA expression microarray from left ventricular tissue samples of MI rats (model group) and non-MI rats (control group). At 4 weeks after the coronary artery occlusion surgery, heatmap of 35 differentially expressed miRNAs between MI and non-MI rats identified by microarray. The miRNA clustering tree is hierarchically clustered on the left, and the sample clustering tree is hierarchically clustered on the top. The samples are clustering significantly into two groups, the control (non-MI rats) and model (MI rats). The color scale of the miRNA represented in the corresponding row shows the relative expression level of miRNAs; green indicates downregulation, while red indicates upregulation.
