Title: Evidence of a novel biomarker, alphas1-Casein, a milk protein, in benign prostate hyperplasia.

Benign prostate hyperplasia is a common disease in elderly men. Although it is a non-malignant disease, it has a significant detrimental impact on the quality of life in patients with late-stage disease. Owing to the lack of specific markers, diagnosis of early-stage benign prostate hyperplasia has been proven unsuccessful. Recently, using two-dimensional electrophoresis, we identified a group of prostatic secretory proteins that are specifically produced by benign prostate hyperplasia cells (Xu et al., Electrophoresis 2003; 24: 1311). In this study, we investigated the potential diagnostic value of one of the secretory proteins, alphas1-Casein, in benign prostate hyperplasia by inmmunohistological staining of normal, benign prostate hyperplasia and prostate cancer tissues. We found that 90% (20 out of 22) of benign prostate hyperplasia tissues showed moderate to strong alphas1-Casein protein expression whereas none of the normal tissues (0 out of 10) and less than 10% of the prostate cancer tissues (3 out of 30) showed similar staining intensity. Our results suggest that alphas1-Casein may be a potential biomarker for early identification of benign prostate hyperplasia patients.
