BACKGROUND A decreased prostatic blood flow could be one of the risk factors for benign prostatic hyperplasia/benign prostatic enlargement. The spontaneously hypertensive rat (SHR) shows a chronic prostatic ischemia and hyperplastic morphological abnormalities in the ventral prostate. The effect of silodosin, a selective alpha1A-adrenoceptor antagonist, was investigated in the SHR prostate as a...

The purpose of this study was to develop an aggressive locally advanced orthotopic prostate cancer model for assessing high-dose image-guided radiation therapy combined with biological agents. For this study, we used a modified human prostate cancer (PCa) cell line, PC3, in which we knocked down a tumor suppressor protein, DAB2IP (PC3‑KD). These prostate cancer cells were implanted into the pro...

The molecular mechanisms leading to prostate cancer remain poorly understood, especially concerning the progression to the metastatic form. SSeCKS, a major protein kinase C substrate with tumor suppressor activity, is likely the rodent orthologue of human Gravin/AKAP12, a scaffolding protein for protein kinases A and C. Gravin was mapped as a single-copy gene to 6q24-25.2, a hotspot for deletio...

BACKGROUND Carbamazepine (CBZ) is a first-line antiepileptic drug (AED), although it is also used for the treatments of psychiatric disorders and neuropathic pain. The CBZ utilization has been associated with male reproductive damage, including hormonal alterations, sexual dysfunction and reduction of sperm quality. The wide and long-term use of the CBZ is a common schedule in children and adol...

The nuclear matrix is the structural component of the nucleus that determines nuclear morphology and organizes the DNA in a three-dimensional fashion that is tissue specific. Previously, some of the nuclear matrix proteins have been reported to be both tissue and cell type specific and are altered with the state of differentiation and transformation. This study demonstrates that the nuclear mat...

AIM To identify flutamide regulated genes in the rat ventral prostate. METHODS Total RNA from ventral prostates of control and flutamide treated rats were isolated. Differentially expressed transcripts were identified using differential display reverse transcriptase polymerase chain reaction. The effect of castration on the expression of flutamide-regulated transcripts was studied. RESULTS ...

Pigment epithelium-derived factor, a potent angiogenesis inhibitor in the eye, is also expressed in the prostate. Prostate size and angiogenesis is increased in pigment epithelium-derived factor knockout mice, and pigment epithelium-derived factor is down-regulated in some prostate cancers. To investigate whether pigment epithelium-derived factor expression correlates with tumor progression, we...

The molecular basis of active ion transport in secretory glands such as the prostate is not well characterized. Rat nongastric H-K-ATPase is expressed at high levels in distal colon surface cell apical membranes and thus is referred to as "colonic." Here we show that the ATPase is expressed in rodent prostate complex in a lobe-specific manner. RT-PCR and Western blot analyses indicate that rat ...

The nuclear matrix is the structural component of the nucleus that determines nuclear morphology and organizes the DNA in a threedimensional fashion that is tissue specific. Previously, some of the nuclear matrix proteins have been reported to be both tissue and cell type specific and are altered with the state of differentiation and transformation. This study demonstrates that the nuclear matr...

Cavernous nerves course along the surface of the prostate gland and are responsible for erectile function. These nerves are at risk of injury during surgical removal of a cancerous prostate gland. In this work, a combination of segmentation, denoising, and edge detection algorithms are applied to time-domain optical coherence tomography (OCT) images of rat prostate to improve identification of ...
