BPH is pathologically characterized by hyperplastic growth in both epithelial and stromal compartments. Androgen signaling is essential for prostate function and androgen blockade is the second-line medical therapy to relieve symptoms of BPH. Here we examined the prostates of probasin promoter-driven prolactin (Pb-PRL) transgenic mice, a robust model of BPH that spontaneously develops prostate enlargement, to investigate prostate regression in response to surgical castration. Serial ultrasound imaging demonstrated very uniform self-limited growth of Pb-PRL prostate volume that is consistent with the benign, limited cellular proliferation characteristic of BPH and that contrasts with the highly variable, exponential growth of murine prostate cancer models. Castration elicited only a partial reduction in prostate volume, relative to castration-induced regression of the normal prostate gland. The anti-androgen finasteride induced a diminished reduction of Pb-PRL prostate volume versus castration. The limited extent of Pb-PRL mouse prostate volume regression correlated with the initial volume of the stromal compartment, suggesting a differential sensitivity of the epithelial and stromal compartments to androgen withdrawal. Indeed, two-dimensional morphometric analyses revealed a distinctly reduced rate of regression for the stromal compartment in Pb-PRL mice. The myofibroblast component of the Pb-PRL prostate stroma appeared normal, but the stromal compartment contained more fibroblasts and extracellular collagen deposition. Like normal prostate, the rate of regression of the Pb-PRL prostate was partially dependent on TGFß and TNF signaling, but unlike the normal prostate, the extent of castration-induced regression was not affected by TGFß or TNF blockade. Our studies show that androgen deprivation can effectively reduce the overall volume of hyperplastic prostate, but the stromal compartment is relatively resistant, suggesting additional therapies might be required to offer an effective treatment for the clinical manifestations of BPH.</p>","PeriodicalId":7438,"journal":{"name":"American journal of clinical and experimental urology","volume":"11 1","pages":"12-26"},"PeriodicalIF":1.5,"publicationDate":"2023-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10009314/pdf/ajceu0011-0012.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9350858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While several urine or tissue-based gene expression assays are available to identify patients with higher risk of adverse disease and to aid in deciding treatment options, there is still a critical need for reliable biomarkers to monitor disease progression and treatment response. Autoantibodies (AAbs) produced by the humoral immune response against tumor associated antigens offer an attractive alternative, as they target a wide variety of prostate cancer specific antigens and can be collected by using clinically non-invasive methods. Herein, we review the transition from traditional methods that identify individual AAbs to high throughput approaches that detect multiple targets simultaneously in patient sera. We also discuss how these approaches improved the sensitivity and specificity of AAb detection and enhanced prostate cancer diagnosis and prognosis. Cancer vaccines offer potential as a novel therapeutic strategy in their ability to stimulate both cell-mediated and antibody-mediated cytotoxic responses. Ongoing efforts aim to identify immunotherapy targets that also stimulate a strong antibody response, since antibodies activated by the anti-cancer humoral response can eliminate cancer cells effectively via several distinct mechanisms. Autoantibodies are useful not only for the diagnosis of prostate cancer, predicting disease progression, and tracking response to treatment, but can also be harnessed as therapeutic agents for prostate cancer treatment.</p>","PeriodicalId":7438,"journal":{"name":"American journal of clinical and experimental urology","volume":"11 2","pages":"79-102"},"PeriodicalIF":1.2,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10165224/pdf/ajceu0011-0079.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9823488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
