Description: Using two-dimensional gel electrophoresis, we investigated the profile of prostatic secretory proteins in human expressed prostatic secretion (EPS) from benign prostate hyperplasia (BPH) patients and compared the patterns with normal controls. We identified three specifically expressed proteins, including prostate secretory protein 61 (PSP61), in EPS from benign BPH patients but absent in normal controls. In addition, we found that PSP61 was a modified isoform of the well-documented PSP-94, which had a perfect matching (100% homology) to the first 61 amino acids of the PSP-94 protein but with a deleted C-terminus. This shortened PSP61 was not due to alternative splicing of the PSP-94 gene at transcription level. Our results provide first evidence on the possibility of using PSP61 as a specific biological marker for diagnosis of BPH.
