Outline of Final Research Achievements |
Although RM2 antigen is a new histological marker for prostate cancer that may reflect the tumor stage, the target proteins carrying RM2 antigen are yet unclear. To identify the target proteins, we focused on amino acid sequence of the 50kDa protein that reacts strongly to RM2 antibody. Histological expression of several candidate proteins in prostate cancer was significantly associated with Gleason score. Among these, urine level of a candidate protein in the patients with prostate cancer decreased compared to those with benign prostate. These results suggested that these candidate proteins would be useful as a new histological or urine marker of prostate cancer.
