Discriminant powers of the DEGs between T-CMT and T-control and gene ontology enrichment analysis. The result of principal component analysis (PCA) showing a visible separation of the expression level of 269 DEGs between the T-CMT and the T-control (A). The hierarchical congregating method of the heat map shows the distinct differences of expression levels of the 269 DEGs between the T-CMT and the T-control (B). The result of k-means clustering method showing that DEGs can be divided into two groups according to their expression pattern (C). The pie diagram showing the GO enrichment analysis in terms of the biological processes, the cellular components, and molecular functions of the 269 DEGs of CMT. "n" indicates the number of genes having a corresponding GO term and "p" indicates its p-value (D-F).
