In the normal prostate, Ang II immunoreactivity was localized to the basal layer of the epithelium and AT<jats:sub>1<\/jats:sub> receptor immunostaining was found predominantly on stromal smooth muscle and also on vascular smooth muscle of prostatic blood vessels. Ang II immunoreactivity was markedly increased in hyperplastic acini in BPH compared with acini in the normal prostate (normal: 7.4\u00b10.2%, <jats:italic>n<\/jats:italic>=5\u2009vs. BPH: 22.7\u00b11.9%, <jats:italic>n<\/jats:italic>=5, <jats:italic>p<\/jats:italic>&lt;0.001). However, AT<jats:sub>1<\/jats:sub> receptor immunoreactivity was significantly decreased in BPH compared with the normal prostate [normal: 16.4\u00b12.2%, <jats:italic>n<\/jats:italic>=4\u2009vs. BPH: 9.4\u00b11.3%, <jats:italic>n<\/jats:italic>=5, <jats:italic>p<\/jats:italic>&lt;0.05 (<jats:italic>p<\/jats:italic>=0.025)]. The present study demonstrates the presence of Ang II peptide in the basal layer of the epithelium and AT<jats:sub>1<\/jats:sub> receptors on stromal smooth muscle, suggesting that Ang II may mediate paracrine functions on cellular growth and smooth muscle tone in the human prostate. Furthermore, AT<jats:sub>1<\/jats:sub> receptor down\u2010regulation in BPH may be due to receptor hyperstimulation by increased local levels of Ang II in BPH. These data extend previous findings in support of the novel concept that overactivity of the renin\u2013angiotensin system (RAS) may be involved in the pathophysiology of BPH.
