Figure 5. Bioinformatic analysis of PPI-enriched and hub genes. (A) PPI of potential hub target genes. (B) The expression of hub genes in TNBC and the correlation analysis with the overall survival time of patients. (C–J) Expression maps of MUC1, APOE, PLAU, CDK1, PDGFRB, CCND1, ROCK2, and PPARA in TNBC patients and normal tissues. (K–N) Impact of ROCK2, PLAU, PDGFRB, and CCND1 expression on the survival of TNBC patients.
