E-cadherin and beta-catenin are component of adherens junctions in epithelial cells. Loss of these proteins have been associated with progression of prostatic diseases. We performed immunohistochemistry for E-cadherin, beta-catenin and Ki-67 on canine prostatic lesions. We analyzed the expression of these antibodies in benign prostatic hyperplasia (BPH, n = 22), in pre neoplastic lesions Prostatic Intra-epithelial Neoplasia (PIN), n = 3 and Prostatic Inflammatory Atrophy (PIA), n = 7 and prostate carcinoma (PC, n = 10)...

β-Hexosaminidase, involved in degradation of glycoproteins and glycosphingolipids, is altered in several tumours leading to enhanced migration capacity. To date, the expression of the β-hexosaminidase isoenzymes in prostate cancer cells has not been elucidated. By using PC3, LNCaP, DUCaP, MDAPCa 2b, and hyperplasic prostate (BPH-1) cell lines, we analysed the β-hexosaminidase activity in each cell line and determined β-hexosaminidase α subunit gene expression in PC3, LNCaP, and BPH-1. We then investigated the methylation status of the gene promoter and determined the cellular responses of PC3 and LNCaP after transfection with β-hexosaminidase α subunit...

We present a case of retroperitoneal schwannoma incidentally diagnosed in a patient undergoing surgical drainage of a pelvic abscess as a complication of a prostatic biopsy. A 50-year-old male, suffering from lymphatic leukemia, came to our observation due to lichen ruber planus and ejaculatory pain. The patient underwent a trans-perineal ultrasound-guided biopsy of the right seminal vesicle and of a hypoechoic area documented by ultrasonography. 48 hours after the procedure, the patient had developed: cold sores, shortness of breath with dyspnea, and high fever (40°C)...

REVIEW

Activins and inhibins are regulatory proteins of the reproductive function. Inhibins antagonise the activin signalling at different levels and are responsible for the negative feedback in the regulation of the release of pituitary follicle stimulating hormone (FSH), which, in turn, is promoted by locally produced activins. In the canine ovary, both peptides are expressed by developing follicles and corpora lutea. Activins may play a stimulatory role in follicular development, promoting the aromatase function; inhibins modulate these processes and suppress the hyperplasic/neoplastic stimuli...

Caspases are essential initiators and executioners of apoptosis. Changes in their expression may contribute to the development of proliferative disorders such as cancer, by altering the death-proliferation homeostatic balance. The aim of this work was to analyze the expression of a broad panel of caspases at the epithelial level in human prostate tissues to assess possible prostatic disease-related alterations. We comparatively analyzed by immunohistochemistry the expression of pro-caspase-3, pro-caspase-8, pro-caspase-9, cleaved caspase-3, cleaved caspase-8, and caspase-7, in normal and pathologic (benign hyperplasic, premalignant [high-grade intraepithelial neoplasia], and cancerous [prostate cancer]) human prostate epithelium...

Clioquinol (5-chloro-7-iodo-8-quinolinol) is a copper ionophore that was used primarily during the 1950-1970s as an oral antimicrobial agent. It has been established that clioquinol displays toxicity towards malignant cells, inducing caspase-dependent apoptosis. In the present study we therefore investigated the effect of clioquinol on the XIAP [X-linked IAP (inhibitor of apoptosis protein)], as one of its primary functions is to hinder caspase activity and suppress apoptotic cell death. Clioquinol treatment caused cytoplasmic XIAP to rapidly relocate to the nucleus in multiple human transformed (hyperplasic and carcinoma) prostate lines...

Prostate cancer (PCa) is the most commonly diagnosed cancer in men. The etiology of PCa in humans is multifactorial and includes age, ethnicity, environmental factors, and other unknown causes. Epidemiological and experimental evidence has shown that cadmium is associated with PCa both in humans and rodents. This metal can act as an endocrine disruptor during prostate development, and it induces prostate lesions late in life. In this study, we investigated the effects of low-dose cadmium on rat prostate morphology during puberty...

Galactose-specific lectins (Gal-lectins) were isolated from the mitochondrial fraction of prostate post-operational hyperplasic tissue of two diagnoses: benign prostate hyperplasic tissue with low-grade intraepithelial neoplasia (LGPIN) and benign prostate hyperplasic tissue with atypical adenomatous hyperplasia (AAH). They had similar molecular weight and other properties. Effects of these lectins were investigated in vitro model experiments on bovine liver cells mitochondrial properties. Time-dependent changes: (i) in the amount of H(2)O(2); (ii) redox state of Cu in cytochrome oxidase and (iii) redox state of heme in cytochrome a+a(3) (cyt a+a(3)) of cytochrome c oxidase complex were studied...

BACKGROUND: Numerous studies indicate that cancer cells present an aberrant glycosylation pattern that can be detected by lectin histochemistry. Lectins have shown the ability to recognise these modifications in several carcinomas, namely in the prostate carcinoma, one of the most lethal diseases in man. Thus, the aim of this work was to investigate if the alpha-D-galactose-binding plant lectin frutalin is able to detect such changes in the referred carcinoma. Frutalin was obtained from different sources namely, its natural source (plant origin) and a recombinant source (Pichia expression system)...

Chronic inflammation and reactivation of developmental signaling pathways are both hallmarks of adenocarcinomas. However, developmental and inflammatory processes are generally thought of as distinct and are believed to represent separate paths to carcinogenesis. Here, we show that the inflammatory cytokine interleukin-1alpha (IL-1alpha) plays a critical role in prostate development by activating insulin-like growth factor (IGF) signaling; this process is reiterated during inflammatory reactive hyperplasia to elicit epithelial proliferation...

Benign prostatic hyperplasia (BPH) is a disease that impairs the well-being of many aged men. To alleviate BPH symptoms or to find a cure for this disease, key molecules should be identified that control prostate cell proliferation. Recently, HIF-1alpha has attracted attention in this context, because it is highly expressed in hyperplasic prostates and prevents prostate cell death. Thus, given that vitamin C inhibits HIF-1alpha expression in several malignant tumors, we examined its therapeutic potential in BPH...
