WGCNA of RNA-Seq data from LGG patients and GBM patients. (a) Dendrogram of modules identified by WGCNA. (b) Heatmap of module-GAS5 expression associations. (c) Topological overlap matrix among detected probes from RNA-Seq. (d) Heatmap for module similarity. (e-f) Scatterplot of gene significance for GAS5 expression versus module membership in the salmon (e) and blue modules (f).
