Differential expression of genes analyzed on TCGA data set. a Volcano map of genes between caner tissue compared and normal samples. b Heat map top 100 differentially expressed genes in caner tissue compared with normal samples. c Venn diagram of key gene modules differentially expressed. d Consistent clustering accumulative distribution function (CDF) diagram. e Heat map of consistent clustering. f Kaplan–Meier curves of cancer patients with different clustering subtypes. g TCGA samples were divided into Cluster1:236 cases and Cluster2:68 cases. Volcano map of Cluster2 compared with Cluster1 sample gene. h Heat map of Cluster2 compared with Cluster1 samples. i Venn diagram of differential genes and key genes between subtypes. j Forest map of univariate COX results. k Forest map with multivariate COX results. l The mRNA expression of APOD assayed by qPCR in 10 samples of cervical cancer tissue and normal tissue. m The mRNA expression of APOC1 assayed by qPCR in 10 samples of cervical cancer tissue and normal tissue. n The mRNA expression of SQLE assayed by qPCR in 10 samples of cervical cancer tissue and normal tissue. n = 10. **P = 0.01 compared with normal tissue
