MMP3 and prostate carcinoma: 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.
