CD19, BRCA1, PDGFA, CDKNA1, MMP1, and TLR4 exhibited high PPI degrees and were enriched in the PI3K-AKT signaling pathway, bladder cancer, and microRNAs in cancer; however, only high PDGFA expression levels were associated with poor OS, whereas high BRCA1 and MMP1 expression levels were associated with favorable PFS. This evidence concerns the gene MMP1 and urinary bladder carcinoma.
