Identification of key genes controlling cancer stem cell characteristics in gastric cancer

Figure 2 Weighted gene coexpression network analysis. A: Clustering dendrograms of differentially expressed genes. Each piece of the leaves on the cluster dendrogram corresponds to a gene. The first color band indicates the modules detected by dynamic tree cut methods. The second color band indicates the modules after merging similar modules; B: Correlation between the gene module and mRNA expression-based stemness index (mRNAsi). The correlation coefficient in each cell represents the correlation between the gene module and mRNAsi, which increases in size from blue to red. The corresponding P value is also annotated; C: Scatter plot of module eigengenes in brown. The top right corner is where the key genes are located.
