Optogenetic gene expression systems enable spatial-temporal modulation of gene transcription and cell behavior. Although applications in biomedicine are emerging, the utility of optogenetic gene switches remains elusive in cancer research due to the relative low gene activation efficiency. Here, we present an optimized CRISPR-Cas9-based light-inducible gene expression device that controls gene transcription in a dose-dependent manner. To prove the potential utility of this device, P53 was tested as a functional target in the bladder cancer cell models...

RECQ helicases are a family of enzymes with both over lapping and unique functions. Functional autosomal recessive loss of three members of the family BLM, WRN and RECQL4, results in hereditary human syndromes characterized by cancer predisposition and premature aging, but despite the finding that RECQL5 deficient mice are cancer prone, no such link has been made to human RECQL5. Here we demonstrate that human urothelial carcinoma of the bladder (UCC) has increased expression of RECQL5 compared to normal bladder tissue and that increasing RECQL5 expression can drive proliferation of normal bladder cells and is associated with poor prognosis...

Novel minimally invasive treatment options for the management of male lower urinary tract symptoms (LUTS) due to bladder outlet obstruction (BOO) aim to provide equal efficacy compared to standard techniques with a more favourable safety profile. The preservation of all aspects of male sexual function including antegrade ejaculation is increasingly important to patients. It should be ideally performed in an outpatient setting under local anesthesia to assure a short recovery time. Novel injectables for intraprostatic application (botulinum neurotoxin A, NX-1207, PRX302) have emerged and first phase III results could not confirm the promising initial data...

A 24-year-old woman with a high fever presented at our hospital. She had been diagnosed with Kabuki syndrome at the age of 4 years because she had the typical facial features of the condition ; she had undergone living donor renal transplantation 12 years prior. She was prescribed a course of antibiotics to treat pyelonephritis of the transplanted kidney and the high fever disappeared, but the fever developed again 3 days after the discharge. Abdominal computed tomography revealed a tubular structure of recent onset running from the left dorsal side to the lower part of the bladder...

Protein disulfide isomerases A6 (PDIA6) belongs to the PDI family. Recently, PDIA6 was found to have a close association with various cancers. However, there has been little investigation into the biological functions of PDIA6 in bladder cancer (BC). In this study, we explored the expression pattern and functional significance of PDIA6 in BC. We found that PDIA6 was overexpressed in BC tissues and cell lines. The in vitro study showed that PDIA6 downregulation significantly inhibited BC proliferation and invasion...

BACKGROUND: Pathological stage and grade have limited ability to predict the outcomes of superficial urothelial bladder carcinoma at initial transurethral resection (TUR). AT-motif binding factor 1 (ATBF1) is a tumor suppressive transcription factor that is normally localized to the nucleus but has been detected in the cytoplasm in several cancers. Here, we examined the diagnostic value of the intracellular localization of ATBF1 as a marker for the identification of high risk urothelial bladder carcinoma...

OBJECTIVE: Carperitide, alpha-human atrial natriuretic peptide, is used in expectation of protecting the kidney during sepsis in internal care unit; however, the detailed mechanism of action has not been clarified yet. As septic acute kidney injury (AKI) does not induce characteristic histological damage, we aimed assess the effects of carperitide treatment on the decline of renal function during lipopolysaccharide-induced AKI by using real-time intravital imaging technique. DESIGN AND METHOD: The renal function was analyzed by the bolus-shot FITC-inulin kinetics method that visualizes the tubular flow after free filtration from glomeruli...

Many studies informed that microRNAs (miRNAs) could function as diagnostic and prognostic indicators in several cancers. The aims of this study were to explore the expression of miR-630 in bladder urothelial carcinoma and its clinical significance for the evaluation of cancer prognosis. A total of 116 patients with bladder urothelial carcinoma were obtained in this retrospective study between May, 2012 and Sep. 2015. Quantitative real-time PCR (qRT-PCR) was conducted to evaluate the expression level of miR-630...

PURPOSE: Men affected by multiple sclerosis often experience neurogenic overactive bladder (OAB), lower urinary tract symptoms and erectile dysfunction (ED). The aim of the study was to investigate modifications of urinary and sexual functions after administration of daily tadalafil (TAD) 5 mg. METHODS: Twenty men were enrolled in a single-blind, 4-week prospective study while 10 men without treatment served as controls. Primary outcomes were changes from baseline of International Prostate Symptom (IPSS), OAB questionnaire (OAB-q-short form) and International Index of Erectile Function (IIEF-5) scores...

INTRODUCTION AND HYPOTHESIS: We describe the rationale and methodology for a study comparing mind-body treatment and pharmacotherapy in women with urgency urinary incontinence (UUI). To explore brain associations in UUI, a subset of patients will also undergo functional magnetic resonance imaging (fMRI). We hypothesize that hypnotherapy, a mind-body intervention, will be at least as effective as pharmacotherapy in treating UUI. We also hypothesize that fMRI findings will change following treatment, with changes potentially differing between groups...

INTRODUCTION: The bladder exstrophy-epispadias complex (BEEC) represents a spectrum of malformations that affect the anatomical and functional structure of the urogenital system. The parents of patients affected by this condition are subject to particularly stressful situations, such as worrying about their child's health, long hospital stays, concerns about the health and constant need for personal care for their children, that can profoundly compromise the quality of family life. OBJECTIVE: The objective of this explorative qualitative study is to evaluate the social situation and the psychological strategies implemented by the mothers of children between 6 and 10 years of age who are affected by BEEC...

PURPOSE: Clinical trials in glioma patients with neurocognitive deficits face challenges due to lacking or unreliable patient self-reports on their health-related quality of life (HRQOL). Patient-proxy data could help solve this issue. We determined whether patient-proxy concordance levels were affected by patients' neurocognitive functioning. METHODS: Patient and patient-by-proxy HRQOL ratings were assessed via SF-36 and EORTC QLQ-BN20, respectively, in 246 patients...

INTRODUCTION: Postprostatectomy incontinence significantly impairs quality of life. Although bladder neck intussusception has been reported to accelerate urinary recovery after open radical retropubic prostatectomy, its adaption to robotic surgery has not been assessed. Accordingly, we describe our technique and compare outcomes between men treated with and without bladder neck intussusception during robot-assisted laparoscopic prostatectomy. MATERIALS AND METHODS: We performed a comparative trial of 48 men undergoing robot-assisted laparoscopic prostatectomy alternating between bladder neck intussusception (n = 24) and nonintussusception (n = 24)...

Urinary bladder function consists in the storage and controlled voiding of urine. Translational studies require animal models that match human characteristics, such as Octodon degus, a diurnal rodent. This study aims to characterize the contractility of the detrusor muscle and the morphology and code of the vesical plexus from O. degus. Body temperature was measured by an intra-abdominal sensor, the contractility of detrusor strips was evaluated by isometric tension recording, and the vesical plexus was studied by electrical field stimulation (EFS) and immunofluorescence...

INTRODUCTION AND HYPOTHESIS: Pelvic floor (PF) dysfunction in patients with cystic fibrosis (CF) is poorly understood due to lack of research. The aim of this study was to examine the prevalence, risk factors and bothersomeness of PF dysfunction and its implications for the clinical management of CF. METHODS: Of 64 adults with CF approached at a tertiary hospital, 60 were surveyed. A clinically meaningful score on the Australian Pelvic Floor Questionnaire (APFQ) is ≥1 in each of the bladder, bowel, sexual function and prolapse sections or a global PF score of ≥3...
