Qi-Shen-Yi-Qi Dripping Pills Promote Angiogenesis of Ischemic Cardiac Microvascular Endothelial Cells by Regulating MicroRNA-223-3p Expression

Figure 5

(a) The heat map diagram displayed the results of the two-way hierarchical clustering of miRNAs and samples. Each row represented a miRNA and each column stood for a sample. The miRNA clustering tree was displayed on the left, and the sample clustering tree appeared at the top. Cluster analysis arranged samples and miRNAs into groups based on their expression levels. Red indicated highly relative expression, and green indicated low relative expression. (b) The results of microarray assay of mir-223-3p were confirmed by real-time PCR in the same set of samples. ΔCt values were normalized to U6 levels. The results were expressed as . , .
