Extraction of DEGs related to SARS-CoV-2 co-expression genes and construction of the PPI network. A Volcano plot of DEGs between breast cancer tumor tissues and adjacent normal tissues. B Heatmap of WGCNA module correlations related to DEGs. C Scatter plot of the module (blue) with the strongest correlation to breast cancer. D Venn diagram of DEGs, WGCNA, and SARS-CoV-2 genes. E GeneMANIA report for the 16 co-expression genes. F Heatmap of correlations among the 16 co-expression genes. *p < 0.05, **p < 0.01, ***p < 0.001
