Outline of Final Research Achievements

We have previously reported that a C-terminal PSA fragment composed of 19 amino acid residues (YTKVVHYRKWIKDTIVANP) with 2331 Da was statistically more abundant in post-digital examination urine of prostate cancer patients compared with in that of benign prostate hypertrophy patients by using MALDI-DIT-TOF/MS. In this study we have constructed quantitative analytical methods of the peptide using commercially available MALDI TOF/MS equipment. We have also evaluated expression of the peptide in prostate cancer cell lines and prostate cancer human tissues and finally detected in prostate cancer tissues but not in prostate cancer cell lines. In order to evaluate molecular markers for castration-resistant prostate cancer, we used iTRAQ method for comprehensive analysis of proteins expressed in LNCaP and AILNCaP cells. Up-regulated proteins in AILNCaP cells belongs to neuronal projection development and oxidation-reduction process by analysis of STRING database.
