endocrine/exocrine glands
• increase in number CD45+ leukocytes in prostate tissue as compared to control (lacking JAG1 over expression)
• prostate tissue in 15/16 mutant mice contains large papillary structures with complex glandular architecture
• blood vessel density in prostate is 1.8 fold more than in control
• increased collagen deposition at the prostatic peri-glandular spaces
• presence of reactive stroma
• stromal cell layer is disrupted and thinner with increased vimentin staining in peri-glandular stromal cells
• prostate tissues contain more inflammatory foci as compared to controls (lacking JAG1 overexpression)
• 62.5% mutant mice (as compared to 20% in controls lacking JAG1 overexpression) have a mass of poorly differentiated adenocarcinoma extended into lumen of seminal vesicles and replacing the normal lining of epithelium
• mice develop high grade prostatic intraepithelial neoplasia at 32 weeks and focal adenocarcinoma by one year
• mice develop high grade prostatic intraepithelial neoplasia at 32 weeks and focal adenocarcinoma by one year
• mice develop a higher grade reactive stroma with lymphocytic infiltration as compared to control (lacking JAG1 overexpression)
