Establishment of weighted gene coexpression network. (a) Differential genes between C2 and C1 were analyzed in the “limma” package, with red representing upregulated genes and blue representing downregulated genes. (b) Clustering of samples from different subtypes of C1 and C2. (c, d) According to scale independence and mean connectivity, the soft threshold is determined to be 6, is 0.73, and scale-free network is constructed. (e) After the elimination of the first 50% of the smallest MAD genes, they were combined into different modules according to the coexpression relationship of the genes. (f) Except gray, the remaining three modules are correlated with the subtype, and the blue module has the greatest correlation.
