BACKGROUND: Urocortin (UCN) is a recently described neuropeptide member of the CRF family, responsible for the secretion of the proopiomelanocortin-derived peptides from the pituitary gland. Although previous results have demonstrated the synthesis of several neuroendocrine factors in the prostate, no studies have been carried out on the expression of UCN in the human gland. METHODS: UCN expression was evaluated in benign prostatic hyperplasia and prostatic tumor tissues by RT-PCR and immunohistochemistry. RESULTS: UCN mRNA and peptide were demonstrated in all specimens tested. In nonneoplastic tissues, UCN was localized in the secretory luminal epithelial and basal layer cells, in the smooth muscle component of the stroma, and in lymphoid infiltrates. An intense immunostaining was evident in prostate adenocarcinoma cells. CONCLUSIONS: The results of the present study demonstrate for the first time UCN expression in the human prostate and in prostate cancer, and suggest a potential involvement of UCN in prostate physiopathology.

Abstract

BACKGROUND: Urocortin (UCN) is a recently described neuropeptide member of the CRF family, responsible for the secretion of the proopiomelanocortin-derived peptides from the pituitary gland. Although previous results have demonstrated the synthesis of several neuroendocrine factors in the prostate, no studies have been carried out on the expression of UCN in the human gland. METHODS: UCN expression was evaluated in benign prostatic hyperplasia and prostatic tumor tissues by RT-PCR and immunohistochemistry. RESULTS: UCN mRNA and peptide were demonstrated in all specimens tested. In nonneoplastic tissues, UCN was localized in the secretory luminal epithelial and basal layer cells, in the smooth muscle component of the stroma, and in lymphoid infiltrates. An intense immunostaining was evident in prostate adenocarcinoma cells. CONCLUSIONS: The results of the present study demonstrate for the first time UCN expression in the human prostate and in prostate cancer, and suggest a potential involvement of UCN in prostate physiopathology.
