Notably, four proteins including plasminogen activator urokinase (PLAU), platelet-derived growth factor subunit A (PDGFA), matrix metalloproteinase 3 (MMP3), and neuroblastoma RAS viral oncogene homolog (NRAS) were identified within the prostate cancer pathway, highlighting their potential as biomarkers for the early diagnosis and prognosis of prostate cancer. Here, PDGFA is linked to prostate cancer.
