Figure 3. Identification of co-expression modules for miRNAs by WGCNA. (A, B) The scale-free fit index and the mean connectivity for various soft-thresholding powers (β) were optimized. (C) Cluster dendrogram of miRNAs based on the 1-TOM. (D) Heatmap of the correlation between module eigengenes and sample types. (E) Scatter plot of module eigengenes for ccRCC samples in the turquoise module.
