Identification of PCDEGs by array screening. A Heatmap of the PCDEGs between tumor group and normal group. blue: low expression level; red: high expression level (B) Protein–protein interaction network between these genes(cutoff = 0.5). C The co-expression between these genes(cutoff = 0.5). ***p < 0.001, **p < 0.01, *p < 0.05
