Analysis of the co-expression of genes with differential expression. (a) The optimal soft threshold for the PD GSE16134 database. (b) The optimal soft threshold for TCGA dataset for BC. (c) The cluster dendrogram for the co-expression of genes in the PD GSE16134 database. (d) The cluster dendrogram of co-expressed genes in TCGA dataset for BC. (e) Heatmap of the module-trait relationships in the PD GSE16134 database. (f) Heatmap of the module-trait connections in TCGA dataset for BC. (g) The Venn diagram showed that 147 genes overlapped in the BC and PD modules. PD: periodontitis; BC: breast cancer.
