WGCNA co-expression network analysis. (A–B). WGCNA analysis of tumor samples in the GSE12452 data set. A total of 12 significantly correlated modules were obtained, among which MEblue showed the strongest correlation with high expression of AURKA; (C–D). WGCNA analysis of tumor samples in the GSE13597 data set. A total of 17 significantly correlated modules were obtained, among which MEblue showed the strongest correlation with high expression of AURKA; (E). Venn diagram results of genes and differential genes of the most significant related modules in WGCNA. A total of 36 hub genes were identified. WGCNA, Weighted Gene Co-Expression Network Analysis; TOM, Topological overlap matrix; ME, Module eigengene; AURKA, Aurora kinase A.
