Castration‑resistant prostate cancer (CRPC) is difficult to treat in current clinical practice. Hypoxia is an important feature of the CRPC microenvironment and is closely associated with the progress of CRPC invasion. However, no research has been performed on the immune escape of CRPC from NK cells.

Castration-resistant prostate cancer (CRPC), also known as androgen-independent prostate cancer, frequently develops local and distant metastases, the underlying mechanisms of which remain undetermined. In the present study, surgical specimens obtained from patients with clinical prostate cancer were investigated, and it was revealed that the expression levels of ataxia telangiectasia mutated kinase (ATM) were significantly enhanced in prostate cancer tissues isolated from patients with CRPC compared with from patients with hormone‑dependent prostate cancer. CRPC C4‑2 and CWR22Rv1 cells lines were subsequently selected to establish prostate cancer models, and ATM knockout cells were established via lentivirus infection.

The aim of this study is to assess the overall efficacy and safety of photoselective vaporization of the prostate (PVP) with GreenLight 120-W laser versus transurethral resection of the prostate (TURP) for treating patients of benign prostate hyperplasia (BPH) with lower urinary tract symptoms (LUTS). We performed a literature search of The Cochrane Library and the electronic databases, including Embase, Medline, and Web of Science. Manual searches were conducted of the conference proceedings, including European Association of Urology and American Urological Association (2007 to 2012).

Recent studies suggest that SATB1 is a promising therapeutic target for prostate cancer. To develop novel SATB1-based therapeutic agents for prostate cancer, in this study, we aimed to construct ZD55-SATB1, an oncolytic adenovirus ZD55 carrying shRNA targeting SATB1, and investigate its effects on the inhibition of prostate cancer growth and metastasis. ZD55-SATB1 was constructed and used to infect human prostate cancer cell lines DU145 and LNCaP.

Objective: To determine whether there have been any changes in the causes and management of urethral strictures in China.

Patients And Methods: The data from 4,764 men with urethral stricture disease who underwent treatment at 13 medical centres in China between 2005 and 2010 were retrospectively collected. The databases were analysed for the possible causes, site and treatment techniques for the urethral stricture, as well as for changes in the causes and management of urethral strictures.

Objective: To explore the effects of stromal interaction molecule 1 (STIM1) on the expression of apoptosis-related proteins in prostate cancer PC-3 cells.

Methods: We transfected the lentivirus vector STIM1-pGCSIL-GFP carrying STIM shRNA into human hormone-independent prostate cancer PC-3 cells, and 3 days later observed the transfection efficiency by fluorescence microscopy. At 7 days after transfection, we determined the expression of STIM1 in the PC-3 cells by RT-PCR and Western blot and those of apoptosis-related proteins Bcl-2, Bax, survivin and activated Caspase-3 by Western blot.

This study treated the isolation and passage of muscle-derived stem cells (MDSCs) from rat penile corpora cavernosa, detection of stem cell marker expression, observation of their self-renewal and continuous proliferation, and demonstration of their potential to differentiate into smooth muscle cells in co-culture. Muscle-derived stem cells from the rat penile corpora cavernosa were isolated and purified. The expression of stem cell markers Sca-1 and desmin was detected in PP6 cells, thus confirming that the main components of PP6 cells are MDSCs.

Purpose: The objective of this study was to evaluate the safety and feasibility of single channel laparoscopy in the treatment of patients with varicocele.

Patients And Methods: Ninety patients with clinically palpable varicoceles were randomly assigned to receive laparoendoscopic single-site with a single channel varicocele ligation (LESS[sc]-VL) (n=45) or conventional transperitoneal laparoscopic varicocele ligation (CTL-VL) (n=45). Patient characteristics, perioperative details, total procedural cost, time to return to work, visual analogue scale (VAS) pain score, semen parameters, and cosmetic results were recorded.

Prostate cancer (PCa) stem/progenitor cells are known to have higher chemoresistance than non-stem/progenitor cells, but the underlying molecular mechanism remains unclear. We found the expression of testicular nuclear receptor 4 (TR4) is significantly higher in PCa CD133(+) stem/progenitor cells compared with CD133(-) non-stem/progenitor cells. Knockdown of TR4 levels in the established PCa stem/progenitor cells and the CD133(+) population of the C4-2 PCa cell line with lentiviral TR4 siRNA led to increased drug sensitivity to the two commonly used chemotherapeutic drugs, docetaxel and etoposide, judging from significantly reduced IC50 values and increased apoptosis in the TR4 knockdown cells.
