Proteomic analysis of voided urine after prostatic massage from patients with prostate cancer: a pilot study.
OBJECTIVES: Serum prostate-specific antigen measurements are widely used for the early detection of prostate cancer but lack specificity, thus warranting the search for additional biomarkers. METHODS: Two-dimensional gel electrophoresis followed by matrix-assisted laser desorption ionization-time of flight-mass spectroscopy (MALDI-TOF-MS) analysis was used to investigate the protein profiles of voided urine after prostatic massage from 6 patients with histologically confirmed prostate cancer ...Expand abstract
