INTRODUCTION: Prostate cancer is the most common malignant disease in men. The number of cases of prostate cancer has increased dramatically in recent 20 years. Radical prostatectomy is a surgical method for the first-line treatment of localised prostate cancer. We performed the first robotic-assisted radical prostatectomy on December 16th, 2005, achieved the boundary of 1000 robotic-assisted radical prostatectomies in 2012, and in 2015, we successfully completed the 1500th robotic-assisted operation on the prostate...

The Italian national health system provides screening to detect breast, colorecatal and cervical cancers, however, population adherence is not as high as expected. Smartphones and their applications (apps) could be used as a tool to communicate with the population and to help improve adherence. The aim of this study was to analyze the features and functions of smartphone applications aimed at secondary prevention of oncological diseases. In February 2016, we reviewed online app stores, using specific key-words, to search for available apps for cancer screening...

Almost all primary prostate cancers (PCs) and PC cell lines express calcitonin (CT) and/or its receptor (CTR), and their co-expression positively correlates with their invasiveness. Activation of the CT-CTR axis in non-invasive LNCaP cells induces an invasive phenotype. In contrast, silencing of CT/CTR expression in highly metastatic PC-3M cells markedly reduces their tumorigenicity and abolishes their ability to form distant metastases in nude mice. Our recent studies suggest that CTR interacts with zonula occludens 1 (ZO-1) through PDZ interaction to destabilize tight junctions and increase invasion of PC cells...

Kallistatin was first identified in human plasma as a tissue kallikrein-binding protein and a serine proteinase inhibitor. Kallistatin via its two structural elements regulates differential signaling cascades, and thus a wide spectrum of biological functions. Kallistatin's active site is essential for: inhibiting tissue kallikrein's activity; stimulating endothelial nitric oxide synthase and sirtuin 1 expression and activation; and modulating the synthesis of the microRNAs, miR-34a, miR-21 and miR-203. Kallistatin's heparin-binding site is crucial for antagonizing the signaling pathways of vascular endothelial growth factor, tumor necrosis factor-α, Wnt, transforming growth factor-β and epidermal growth factor...

MNS16A, a functional polymorphic tandem repeat minisatellite, is located in the promoter region of an antisense transcript of the human telomerase reverse transcriptase gene. MNS16A promoter activity depends on the variable number of tandem repeats (VNTR) presenting varying numbers of transcription factor binding sites for GATA binding protein 1. Although MNS16A has been investigated in multiple cancer epidemiology studies with incongruent findings, functional data of only two VNTRs (VNTR-243 and VNTR-302) were available thus far, linking the shorter VNTR to higher promoter activity...

PURPOSE OF REVIEW: Comparative effectiveness research plays a vital role in healthcare delivery by guiding evidence-based practices. We performed a state-of-the-art review of comparative effectiveness research in the urology literature for 2016, utilizing a systematic approach. Seven high-impact papers are reviewed in detail. RECENT FINDINGS: Across the breadth of urology, there were several important studies in comparative effectiveness research, of which we will highlight two randomized controlled trials and five observational trials: radiotherapy, prostatectomy, and active monitoring have equivalent mortality outcomes in patients with localized prostate cancer; the ideal modality of patient education is yet to be determined, and written education has minimal effect on patient perception of prostate specific antigen screening; robotic prostatectomy is associated with higher perioperative complication rates on a population basis; racial disparities exist in incontinence rates after treatment for localized prostate cancer, but not in irritative, bowel, or sexual function; androgen deprivation therapy is associated with higher fracture, peripheral artery disease, and cardiac-related complications than bilateral orchiectomy; robotic and open cystectomy offer comparable cancer-specific mortality and perioperative outcomes; and bonuses for low-cost hospitals can inadvertently reward low-quality hospitals...

Long non-coding RNAs (lncRNAs) have been demonstrated to play essential roles in diverse cellular processes and biological functions. Exploring the functions associated with lncRNAs may help provide insight into their underlying biological mechanisms. The current methods primarily focus on investigating the functions of individual lncRNAs; however, essential biological functions may be affected by the combinatorial effects of multiple lncRNAs. Here, we have developed a novel computational method, LncRNAs2Pathways, to identify the functional pathways influenced by the combinatorial effects of a set of lncRNAs of interest based on a global network propagation algorithm...

The structural and functional basis of the genome is provided by the three-dimensional (3D) chromatin state. To enable accurate gene regulation, enhancer elements and promoter regions are brought into close spatial proximity to ensure proper, cell type-specific gene expression. In cancer, genetic and epigenetic processes can deregulate the transcriptional program. To investigate whether the 3D chromatin state is also disrupted in cancer we performed Hi-C chromosome conformation sequencing in normal and prostate cancer cells and compared the chromatin interaction maps with changes to the genome and epigenome...

G protein-coupled receptors (GPCRs) and receptor tyrosine kinases (RTKs) act in concert to regulate cell growth, proliferation, survival, and migration. Metabotropic GABAB receptor (GABABR) is the GPCR for the main inhibitory neurotransmitter GABA in the central nervous system. Increased expression of GABABR has been detected in human cancer tissues and cancer cell lines, but the role of GABABR in these cells is controversial and the underlying mechanism remains poorly understood. Here, we investigated whether GABABR hijacks RTK signaling to modulate the fates of human prostate cancer cells...

The HOX and PBX gene families encode transcription factors that have key roles in establishing the identity of cells and tissues in early development. Over the last 20 years it has become apparent that they are also dysregulated in a wide range of solid and haematological malignancies and have a predominantly pro-oncogenic function. A key mode of transcriptional regulation by HOX and PBX proteins is through their interaction as a heterodimer or larger complex that enhances their binding affinity and specificity for DNA, and there is growing evidence that this interaction is a potential therapeutic target in malignancies that include prostate, breast, renal, ovarian and lung cancer, melanoma, myeloma, and acute myeloid leukaemia...

BACKGROUND: As one of the most common cancers in men, the pathogenesis of prostate cancer has been widely researched. Aberrant activation of the erb-b2 receptor tyrosine kinase 2 (ERBB2) has been found to play a critical role in metastatic prostate cancer. In our previous study, we demonstrated that rs61552325 (Pro1140Ala) located in ERBB2 is strongly correlated to prostate cancer. Therefore, we initially studied the effect of rs61552325 on androgen-independent prostate cancer cell metastasis...

Background Dysregulation of microRNA (miRNA) expression is implicated in cancer development and progression by modulating oncogenes or tumor suppressors at the post-transcriptional level. Methods To investigate the role of miRNAs in prostate cancer (PCa) progression, we performed small RNA-sequencing (RNA-seq) analysis in androgen-dependent LNCaP cells and LNCaP-derived castration-resistant prostate cancer (CRPC) C4-2B cells. For functional validation, we specifically investigated miR-193a-3p, which is highly upregulated in C4-2B cells and modulated by the androgen receptor (AR)...

Cumulative verified experimental studies have demonstrated that microRNAs (miRNAs) could be closely related with the development and progression of human complex diseases. Based on the assumption that functional similar miRNAs may have a strong correlation with phenotypically similar diseases and vice versa, researchers developed various effective computational models which combine heterogeneous biological datasets including disease similarity network, miRNA similarity network, and known disease-miRNA association network to identify potential relationships between miRNAs and diseases in biomedical research...

In discrete choice experiments, patients are presented with sets of health states described by various attributes and asked to make choices from among them. Discrete choice experiments allow health care researchers to study the preferences of individual patients by eliciting trade-offs between different aspects of health-related quality of life. However, many discrete choice experiments yield data with incomplete ranking information and sparsity due to the limited number of choice sets presented to each patient, making it challenging to estimate patient preferences...

Up to 90% of all cancer related morbidity and mortality can be attributed to metastasis. In recent years the study of tumor microenvironment, its cellular and molecular components, and how they can affect neoplastic progression toward metastasis, has become a hot focus in cancer research. Accumulated evidence shows that the formation of metastasis is a multi-step sequential process, in which, the tumor cells continuously interact with the host microenvironment. Host derived factors, i.e. growth factors/inhibitors, angiogenic factors, chemokines, etc...

Drugs that target the Renin-Angiotensin System (RAS) have recently come into focus for their potential utility as cancer treatments. The use of Angiotensin Receptor Blockers (ARBs) and Angiotensin-Converting Enzyme (ACE) Inhibitors (ACEIs) to manage hypertension in cancer patients is correlated with improved survival outcomes for renal, prostate, breast and small cell lung cancer. Previous studies demonstrate that the Angiotensin Receptor Type I (AT1R) is linked to breast cancer pathogenesis, with unbiased analysis of gene-expression studies identifying significant up-regulation of AGTR1, the gene encoding AT1R in ER+ve/HER2-ve tumors correlating with poor prognosis...

Traditional gene fusions are involved in the development of various neoplasia. DUS4L-BCAP29, a chimeric fusion RNA, has been reported to be a cancer-fusion in prostate and gastric cancer, in addition to playing a tumorigenic role. Here, we showed that the DUS4L-BCAP29 fusion transcript exists in a variety of normal tissues. It is also present in non-cancer epithelial, as well as in fibroblast cell lines. Quantitatively, the fusion transcript has a comparable expression in non-cancerous, gastric and prostate cell lines and tissues as in the cancer cell lines and tissues...

PURPOSE: To measure the level of oxytocin in serum and prostate cancer (PCa) tissue and study its effect on the proliferation of PCa cells. RESULTS: Oxytocin level in serum was significantly increased in PCa patients compared with the no-carcinoma individuals. Additionally, the levels of oxytocin and its receptor were also elevated in the PCa tissue. However, no significant difference existed among the PCa of various Gleason grades. Western blot analysis confirmed the previous results and revealed an increased expression level of APPL1...
