Figure 2. Identification of hub modules and candidate hub mRNAs based on WGCNA. (A) Sample clustering dendrogram to detect outliers; (B) Sample clustering dendrogram and trait heatmap; (C) Scale-free fitting index and average connectivity for different soft threshold power (β); (D) mRNA is divided into different modules by hierarchical clustering, and different colors represent different modules; (E) Modules with dissimilarity <25% are merged; (F) Heatmap of correlation between ME and CIS; (G) Scatter plot of mRNAs in green module; (H) Scatter plot of mRNAs in red module.
