Urothelial carcinoma associated 1α (UCA1α) is a novel long non-coding RNA (lncRNA) that regulates bladder cancer proliferation, migration, and invasion. The target genes of UCA1α have, however, not been identified. To address this, a pCDNA3.1(+)-UCA1α over-expression vector was transfected into UM-UC-2 bladder cancer cells. Genes differentially expressed between pCDNA3.1(+)-UCA1α and pCDNA3.1(+) transfected cell were then detected by microarray and bioinformatics analysis. A total of seventy-one differentially expressed genes were identified, including fifty-two up-regulated genes and nineteen down-regulated genes...

PURPOSE: Activation of the phosphatidylinositol 3-kinase (PI3K) pathway occurs in over 40% of bladder urothelial cancers. The aim of this study is to determine the therapeutic potential, the underlying action and resistant mechanisms of drugs targeting the PI3K pathway. EXPERIMENTAL DESIGN: Urothelial cancer cell lines and patient-derived xenografts (PDXs) were analyzed for alterations of the PI3K pathway and for their sensitivity to the small molecule inhibitor pictilisib alone and in combination with cisplatin and/or gemcitabine...

Parkinson's disease (PD) is a common neurodegenerative disorder, characterized by motor and nonmotor symptoms (NMS). Several subsequent studies substantiate the great functional burden related to NMS, their progression, and negative effect on quality of life in PD. Additional evidence indicates interesting relationships between striatal dopaminergic function and NMS. The basal ganglia are implicated in the modulation and integration of sensory information and pain, bladder function is under control of both inhibitory (D1) and facilitatory (D2) dopaminergic inputs, finally reduced dopaminergic activity in the mesocortical and mesolimbic pathways is involved in the development of several NMS including mood, motivational, and cognitive alterations...

Posterior urethral valves are the most common cause of partial bladder outlet obstruction (PBOO) in the pediatric population. Pathological changes in the bladder developed during PBOO are responsible for long-lasting voiding dysfunction in this population despite early surgical interventions. Increasing evidence showed PBOO induces an upregulation of Hypoxia inducible factors (HIFs) and their transcriptional target genes, and they play a role in pathophysiological changes in the obstructed bladders. We hypothesized that blocking HIF pathways can prevent PBOO-induced bladder dysfunction...

Autonomic dysreflexia is a dangerous elevation in blood pressure in people with spinal cord injury (SCI), produced by a spinally-mediated reflex activation of sympathetic vasoconstrictor neurones supplying skeletal muscle and the gut. Current dogma states that, apart from visceral inputs - such as those originating from a distended bladder or impacted colon - autonomic dysreflexia is triggered by noxious inputs below the lesion. However, while selective stimulation of small-diameter afferents in muscle or skin evokes a sustained increase in muscle sympathetic nerve activity and blood pressure, and a transient increase in skin sympathetic nerve activity and decrease in skin blood flow in able-bodied subjects, such noxious inputs have no effects on blood pressure and skin blood flow in SCI individuals...

Ipilimumab (Bristol-Myers Squibb Co., New York, NY) is a novel anticancer medication used for the treatment of metastatic melanoma. The exact mechanism of its action remains unclear; however, data from previous clinical trials postulates the immunomodulatory activity of ipilimumab to enhance therapeutic effectiveness. Ipilimumab was approved by the Food and Drug Administration (FDA) in March 2011 for use in stage III and IV of unresectable metastatic melanoma. We report a single case of acute inflammatory demyelinating polyneuroradiculopthy (AIDP) in the patient treated with ipilimumab for recurrent metastatic melanoma...

Colorectal cancer (CRC) is the third leading cause of cancer-related deaths and a major health problem. High mobility group box 3 (HMGB3), a member of the high-mobility group box (HMGB) family, was reported to be over-expressed in gastric carcinoma and bladder cancer. However, the function of HMGB3 in CRC remains unclear. Here, we found that HMGB3 was up-regulated in CRC at both mRNA and protein levels. qRT-PCR results showed that high expression of HMGB3 had positive correlation with serosal invasion, lymph metastasis, and tumor-node-metastasis (TNM) stage in CRC patient...

Muscle-invasive bladder cancer is an aggressive disease associated with high morbidity and mortality. Radical cystectomy is the mainstay of treatment and has evolved since the first reported cystectomy in 1887 to include pelvic lymph node dissection and the creation of increasingly sophisticated urinary diversions, such as neobladders and pouches, which enable patients to maintain continence. Pioneering work in the 1970s established the therapeutic activity of cisplatin in patients with bladder cancer and resulted in the introduction of cisplatin-based neoadjuvant chemotherapy, which led to the first improvement in survival outcomes in decades...

AIMS: A proof of principle study of a novel wearable device to control neurogenic detrusor over-activity in eight male spinal cord injured subjects using conditional neuromodulation. METHODS: Transrectal stimulation was delivered through the device in response to simultaneously recorded external anal sphincter (EAS) contraction as a marker for neurogenic detrusor overactivity (NDO). The effect of conditional neuromodulation on bladder capacity and maximum detrusor pressure was investigated in addition to reliability of dyssynergic sphincter contraction as a marker for NDO...

AIMS: Percutaneous tibial nerve stimulation (PTNS) is an effective neuromodulation therapy for treating overactive bladder (OAB). The therapeutic effects are achieved by repeatedly applying electrical stimulation through a percutaneous needle electrode that is used to target the tibial nerve (TN). Anatomical studies indicate there can be multiple saphenous nerve (SAFN) branches located near the site of electrical stimulation, and therefore we investigated the possibility of evoking a bladder-inhibitory reflex by electrically activating the SAFN...

Apaziquone (also known as EO9 and Qapzola(TM)) is a prodrug that is activated to DNA damaging species by oxidoreductases (particularly NQO1) and has the ability to kill aerobic and/or hypoxic cancer cells. Areas covered: Whilst its poor pharmacokinetic properties contributed to its failure in phase II clinical trials when administered intravenously, these properties were ideal for loco-regional therapies. Apaziquone demonstrated good anti-cancer activity against non-muscle invasive bladder cancer (NMIBC) when administered intravesically to marker lesions and was well tolerated with no systemic side effects...

Previous work demonstrated restoration of a bioequivalent bladder within 8 weeks of removing the majority of the bladder (subtotal cystectomy or STC) in rats. The goal of the present study was to extend our investigations of bladder repair to the murine model, to harness the power of mouse genetics to delineate the cellular and molecular mechanisms responsible for the observed robust bladder regrowth. Female C57 black mice underwent STC, and at 4, 8, and 12 weeks post-STC, bladder repair and function were assessed via cystometry, ex vivo pharmacologic organ bath studies, and T2-weighted magnetic resonance imaging (MRI)...

Caveolae are membrane invaginations present at high densities in muscle and fat. Recent work has demonstrated that myocardin family coactivators (MYOCD, MKL1), which are important for contractile differentiation and cell motility, increase caveolin (CAV1, CAV2, CAV3) and cavin (CAVIN1, CAVIN2, CAVIN3) transcription, but several aspects of this control mechanism remain to be investigated. Here, using promoter reporter assays we found that both MKL1/MRTF-A and MKL2/MRTF-B control caveolins and cavins via their proximal promoter sequences...

An over-active bladder is a common disorder which influences women's health and quality of life. There is difficulty defining the exact prevalence of the disorder since there are various definitions in the literature. The ICS definition from 2002 on the over-active bladder (OAB) syndrome enables more uniformity, by declaring that OAB syndrome is a symptomatic syndrome defined as presence of urgency with or without urinary incontinence, mostly accompanied by frequency and nocturia. In this article we reviewed the current medical literature on the prevalence of the OAB syndrome by focusing on relevant crosssectional and longitudinal studies, the trend changes during life, co-morbidities, the influence of quality of life and the economic burden following the disorder and its treatment...

BACKGROUND: The ICCS defines OAB by the subjective symptom of urgency; detrusor overactivity (DO) is only implied. While no other symptom is required, OAB can also be associated with urinary frequency, decreased functional bladder capacity, and incontinence. OBJECTIVE: We sought to determine how often these associated findings occur in OAB and what if any uroflow/EMG-defined conditions are found to be associated with it. METHODS: The charts of 548 children (231M, 318F; mean age 9...
