Abstract
INTRODUCTION Bladder cancer (BCa) is the most frequent cancer of the urinary tract, with more than 500,000 reported cases and nearly 200,000 related deaths yearly. Cystoscopy is the standard examination used for the initial diagnosis and follow-up of BCa in the noninvasive stage. However, the American Cancer Society does not include BCa screening in its list of recommended cancer screenings. AREAS COVERED Recently, several urine-based bladder tumor markers (UBBTMs) that identify genomic, transcriptomic, epigenetic, or protein alterations have been introduced, some of which have been approved by the Food and Drug Administration (FDA) to improve its diagnosis and surveillance. Several biomarkers have been found in the tissues and blood of individuals with BCa or predisposed to develop the disease, further enriching our information. EXPERT OPINION From a prevention perspective, alkaline Comet-FISH could be a valuable tool with broad potential for clinical application. Furthermore, a comet assay could be more beneficial for diagnosing and monitoring bladder cancer and determining individual susceptibility. Thus, we recommend further studies to understand the potential of this combined assay in the general population as a potential screening test and in patients initiated into the diagnostic process.

Abstract
The two types of bladder cancer, muscle invasive and non-muscle invasive (NMIBC), are among the most prevalent cancers worldwide. Despite this, even though muscle-invasive bladder cancer is more deadly, NMIBC requires more therapy due to a greater recurrence rate and more extended and expensive care. Immunotherapy, intravesical chemotherapy, cystoscopy, and transurethral resection (TUR) are among the treatments available. Crude scorpion venomand purified proteins and peptides, can suppress cancer metastasis in an in vitro or in vivo context, suppress cancer growth, halt the cell cycle, and cause cell apoptosis, according to an increasing number of experimental and preclinical studies. In this research, three novels discovered peptides (P2, P3 and P4. ProteomeXchange: PXD036231) from Buthotus saulcyi and, Odontobuthus doriae scorpions were used along with a peptide called pantinin (as a control). The phylogenetic tree showed that the peptides belong to Chaperonin HSP60, Chrysophsin2 and Pheromone-binding protein2, respectively. These peptides were docked with four known antigens, BAGE, BLCAP, PRAME and ROR1 related to bladder cancer and three bacterial antigens FliC, FliD and FimH to investigate their antimicrobial and anticancer properties. The results showed that peptides 2 and 3 have the best binding rate. The MD simulation results also confirmed the binding of peptides 2 and 3 to antigens. The penetration power of peptides 2 and 3 in the membrane of cancer cells and bacterial cells was also simulated, and the results of RMSD and PD confirmed it. QSAR suggests that peptides 2 and 3 can act as anti-cancer and anti-microbial peptides.Communicated by Ramaswamy H. Sarma.

Abstract
Bladder cancer is well-known cancer in two forms of muscle-invasive and non-muscle-invasive bladder cancer which is responsible for annual deaths worldwide. Common therapies methods are somewhat successful; however, these methods have the limitations such as the side effects of chemotherapy which necessitate the requirement for new preventive methods against bladder cancer. Hence, we explain a novel designed multi-epitope vaccine against bladder cancer using the immunoinformatics tool. Three well-known BLCAP, PRAM, and BAGE4 antigens were evaluated due to most repetitive CTL and HTL epitopes binding. IFNγ and IL10 inducer potential of selected epitopes were investigated, as well as liner and conformational B-cell epitopes. Human beta-defensin 3 and PADRE sequence were added to construct as adjuvants, along with EAAAK, AAY, and GGGS linkers to fuse CTL and HTL epitopes. Results showed this construct encodes a soluble, non-toxic, and non-allergic protein with 70 kDa molecular weight. Modeled 3D structure of vaccine was docked whit Toll-Like Receptors (TLR) of 7/8. Docking, molecular dynamics simulation and MMBPSA analysis confirmed stability of vaccine-TLR complexes. The immunogenicity showed this construct could elicit humoral and cellular immune responses. In silico and immunoinformatics evaluations suggest that this construct is a recombinant candidate vaccine against bladder cancer.

Abstract
Liquid biopsies are increasingly used for the diagnosis and follow-up of cancer patients. Urine is a body fluid that can be used to detect cancers and others diseases. It is noninvasive and easy to collect. To detect Bladder Cancer (BC), cytology is the first assay used. It is an effective way to detect high grade BC but has a high rate of equivocal results, especially for low grade BC. Furthermore, cystoscopy is used to confirm cytology results and to determine cancer status. Cystoscopy is also effective but highly invasive, and not well accepted by patients, especially for BC follow-up. In this review we survey the numerous assays recently developed in order to diagnose BC at an early stage, and to facilitate the follow-up of patients. We discuss their effectiveness, ease of use, and applications. Finally, we discuss assays that, in the future, could improve the diagnosis and management of BC patients.

Abstract
In this study, we analyzed the prediction accuracy of an autophagy-related long non-coding RNA (lncRNA) prognostic signature using bladder urothelial carcinoma (BLCA) patient data from The Cancer Genome Atlas (TCGA) database. Univariate and multivariate Cox regression analyses showed significant correlations between five autophagy-related lncRNAs, LINC02178, AC108449.2, Z83843.1, FAM13A-AS1 and USP30-AS1, and overall survival (OS) among BCLA patients. The risk scores based on the autophagy-related lncRNA prognostic signature accurately distinguished high- and low-risk BCLA patients that were stratified according to age; gender; grade; and AJCC, T, and N stages. The autophagy-related lncRNA signature was an independent prognostic predictor with an AUC value of 0.710. The clinical nomogram with the autophagy-related lncRNA prognostic signature showed a high concordance index of 0.73 and accurately predicted 1-, 3-, and 5-year survival times among BCLA patients in the high- and low-risk groups. The lncRNA-mRNA co-expression network contained 77 lncRNA-mRNA links among 5 lncRNAs and 49 related mRNAs. Gene set enrichment analysis showed that cancer- and autophagy-related pathways were significantly enriched in the high-risk group, and immunoregulatory pathways were enriched in the low-risk group. These findings demonstrate that an autophagy-related lncRNA signature accurately predicts the prognosis of BCLA patients.

Abstract
BACKGROUND The molecular mechanism of bladder cancer is yet not fully understood. Aim of this study was to compare the levels of BLCA-4 nuclear matrix protein in the urine of patients with bladder cancer and non-affected individuals. MATERIALS AND METHOD The current cross sectional study was conducted on 45 patients with bladder cancer and 45 patients without bladder cancer who were referred to Alzahra Hospital of Isfahan, Iran in 2017. BCLA-4 Urinary Marker was measured in urine of the patients and individuals. Also correlation between the urine levels of BCLA-4 and other variables were evaluated. RESULTS The urine levels of BLCA-4 in the patients with bladder cancer was significantly higher than non-bladder cancer group (P<0.001). There was no significant relationship between urine levels of BLCA-4 with tumor stage and size (P>0.05). CONCLUSION The present study indicated that high urine levels of BLCA-4 was presented in patients with bladder cancer and this tumor marker has a high capability for early diagnosis of the disease, which can be used for screening and follow-up of bladder cancer.

Abstract
Successful treatment of non-muscle invasive bladder cancer (NMIBC) relies heavily on our ability to accurately detect disease typically in the presence of hematuria as well as to detect the early recurrent tumors in patients with a history of NMIBC. Unfortunately, the current biomarker landscape for NMIBC is a work in progress. Cystoscopy continues to be the gold standard, but can still miss 10% of tumors. Therefore, physicians frequently use additional tools to aid in the diagnosis of bladder cancer, such as urinary cytology. The urinary cytology is a good option for high-grade disease; however, it is limited by low sensitivity in detecting low-grade disease, as well as variable interpretation among cytopathologists. Thus, the limitations of cystoscopy and urinary cytology have brought to light the need for more robust diagnostic assays. In this non-systematic review, we discuss the performance, potential advantages or disadvantages of these tests, and the future direction of biomarkers in NMIBC.

Abstract
Background The aim of this study was to determine the clinical significance of the expression levels of bladder cancer-specific antigen-1 (BLCA-1) in the diagnosis of bladder cancer (BC). The study also determined the relationship between BLCA-1 expression levels and the clinical manifestation of BC. Material/Methods Patient samples were derived from 66 cases of BC that presented at the Department of Urology, Affiliated Hospital of Chengde Medical University, were recruited from April 2014 to May 2015, and 64 healthy control cases. Serum and urine BLCA-1 levels were detected by enzyme-linked immunosorbent assay (ELISA). Results Urine BLCA-1 levels in BC patients were significantly higher than that found in healthy controls (P<0.01). BLCA-1 levels in the urine of patients without mucus membrane invasion (Ta) were significantly different from urine levels found in patients with mucus membrane invasion (T1–T4; P=0.022). BLCA-1 levels in the serum of patients without muscular coat invasion (Ta–T1) were significantly different than serum levels of patients with muscular coat invasion (T2–T4; P=0.042). Conclusions BLCA-1 is involved in the appearance and development of BC. Clinical detection of serum and urine BLCA-1 protein levels showed a high level of sensitivity and specificity in diagnosing BC. Further study of the functional expression of BLCA-1 levels as a valuable and novel diagnostic marker in BC is clearly warranted.

Abstract
Bladder cancer (BLCA) is among the most malignant types of cancer. At present, the prognostic tools available for this disease are insufficient. In the present study, the transcriptome of 1,049 BLCA samples from four datasets from the Gene Expression Omnibus and The Cancer Genome Atlas (TCGA) were analyzed. By utilizing the RNA-seq data provided by TCGA, a risk score staging system model was built to predict the outcome of patients with BLCA using random forest variable hunting and Cox multivariate regression. A total of 7 genes, including zinc finger protein 230, Bcl2-like 14, AHNAK, transmembrane protein 109, apolipoprotein L2, advanced glycation end-product specific receptor and amine oxidase, copper containing 2 were identified as predicting the survival time of patients with BLCA. The patients with a low risk score had a significantly higher survival rate than those with a high-risk score both in the training and validation datasets. Association analyses between risk score and other clinical information were additionally performed; it was demonstrated that the risk score was significantly associated with pathological stage. A nomogram was plotted to compare risk score and other clinical information. The risk score spanned the greatest range of points, indicating the relative accuracy of risk score. In summary, the risk staging model based on the expression of 7 genes is robust and performs more effectively than other clinical information in predicting a prognosis.

Abstract
Despite advances in the surgical and medical treatment of bladder cancer, there have only been minor improvements in mortality and morbidity rates over the past decades. Urine-based markers help to improve diagnosing bladder cancer with the aim of complementing or probably in future replacing cystoscopy. Biomarkers may allow individualized risk stratification and support decision-making regarding therapy and follow-up. This review summarizes the existing urine-based biomarkers in bladder cancer. We conducted a comprehensive review of the literature. We conducted a PubMed/Medline based research on English language articles and selected original articles and review articles that provided both description and assessment of urinary markers at time of screening, initial diagnosis, monitoring and prognostic evaluation of urothelial bladder cancer. Our research covered studies published between 2000 and 2017. The aim of this study was to give clinicians keys to understand the existing or promising urinary markers that may become alternatives to cytology/cystoscopy pair in the near future. Many urinary markers are now available, often with superior sensitivity to cytology. Their uses have been evaluated in numerous clinical situations in addition to the time of initial diagnosis and surveillance such as cases of isolated macroscopic hematuria or atypical cytology discordant with the rest of the explorations. However, their superiority over the cytology/cystoscopy association is not demonstrated. These new markers are lacking for the most part of standardization and simplicity making their use in common practice difficult. the types and forms of these new markers are very heterogeneous among themselves and between the studies that evaluate them. Well-designed protocols and prospective, controlled trials are needed to provide the basis to determine whether integration of urine- and blood-based biomarkers into clinical decision-making will be of value for bladder cancer detection and screening in the future.

Abstract
Purpose of Review This review aims to evaluate research surrounding the utility of urinary biomarkers to detect bladder cancer and predict recurrence. Recent Findings Recent research has focussed on the evaluation of genetic markers found in urine to provide diagnostic and prognostic information. Furthermore, the isolation and characterisation of extracellular vesicles (EVs) from the urine patients with bladder cancer provide an exciting new development in biomarker research that is set to expand in the coming years. Summary Current urinary biomarker research is a broad field that encompasses the evaluation of urinary proteins, DNA, RNA and EVs to detect signatures that can be used to predict the presence of bladder cancer and provide prognostic information. EVs in particular offer an exciting and novel perspective in the search for accurate bladder cancer biomarkers.

Abstract
BACKGROUND The interaction of environmental factors with genetic susceptibility and detoxification level seems to be an important causative factor in bladder cancer (BC). The aim of this study was to look for a BC marker panel which reflects the environmental risk. The nuclear matrix protein 22 (NMP22), bladder cancer-4 (BLCA-4), and total level proteins NMP22 and BLCA-4 (NMBL) in BC patients with genetic predisposition NAT2 (classified as slow acetylators, SA), DNA damage (8-OHdG), and detoxification by isoenzyme GSTπ activity were measured. MATERIALS AND METHODS The urine and blood from 91 BC patients and controls were examined, also according to tumor stage (T) and grade (G). The participants completed a questionnaire in order to evaluate environmental risk. RESULTS Most patients (75.3%) were previous or actual smokers. The levels of 8-OHdG, NMP22, BLCA-4, NMBL, and GSTπ were significantly higher in BC (p ≤ 0.001). The majority of patients (59.3%) were slow acetylators (SA). The highest BLCA-4/8-OHdG correlation was observed in total BC and SA smokers. CONCLUSIONS The total pool of nuclear matrix proteins in the urine (NMBL) has a higher diagnostic value in bladder cancer than single proteins. The particular value of BLCA-4 and GSTπ in the aspect of environmental risk was noted.

Abstract
The search continues for optimal markers that can be utilized to improve bladder cancer detection and to predict disease recurrence. Although no single marker has yet replaced the need to perform cystoscopy and urine cytology, many tests have been evaluated and are being developed. In the future, these promising markers may be incorporated into standard practice to address the challenge of screening in addition to long-term surveillance of patients who have or are at risk for developing bladder cancer.

Abstract
OBJECTIVE This study aims to investigate the application value of tumor abnormal protein (TAP) examination in the diagnosis of urothelial carcinoma of the bladder. METHOD Abnormal sugar chain glycoproteins in the peripheral blood of 87 patients with urothelial carcinoma of the bladder were detected, and compared with non-tumor patients accompanied by hematuria. RESULT TAP examination showed that the positive rate of the abnormal sugar chain glycoprotein in the peripheral blood of the 87 patients with urothelial carcinoma of the bladder was 78.16%, whereas that of the non-tumor patients was 10.81%. The former is significantly higher than the latter (P<0.01). CONCLUSION TAP examination can be used to detect urothelial carcinoma of the bladder, and would be helpful in the diagnosis of urothelial carcinoma of the bladder by combining the clinical signs and symptoms.

Abstract
Increasing evidence has demonstrated that changes in plasma nuclear matrix proteins are specific markers of cancer. Furthermore, proteomic analysis has revealed that calponin-h2 is upregulated in human breast cancer tissue, but is absent in healthy and benign controls. However, the roles of levels of plasma calponin-h2 in the diagnosis of breast cancer and its association with clinicopathological parameters remain to be elucidated. In the present study, the plasma levels of calponin-h2 in patients with breast cancer, benign breast disease and in healthy controls were examined using an enzyme-linked immunosorbent assay. The expression levels of calponin-h2 in invasive breast cancer and normal breast tissues were measured using immunohistochemistry. Statistical analyses examined the association between the levels of plasma calponin-h2 and clinicopathological parameters. The results demonstrated that the plasma level of calponin-h2 in breast cancer was significantly higher than those in the healthy control and benign breast disease groups (P<0.05). The combination of calponin-h2, carcinoembryonic antigen, carbohydrate antigen 15-3 improved the diagnosis of breast cancer. The plasma levels of calponin-h2 PR-breast cancers was significantly higher, compared with PR+ breast cancers (P=0.033), and the plasma levels of calponin-h2 in patients with breast cancer aged >50 years was significantly higher than in patients ≤ 50 years of age (P=0.001). No association was found between the level of plasma calponin-h2 and other clinicopathological parameters of breast cancer. Taken together, these results indicated that calponin-h2 may be a useful marker of breast cancer.

Interaction network analysis of differentially expressed genes and screening of cancer marker in the urine of patients with invasive bladder cancer. Int J Clin Exp Med 2015; 8:3619-3628. [PMID: 26064257 PMCID: PMC4443091] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2014] [Accepted: 02/12/2015] [Indexed: 06/04/2023]
Abstract
OBJECTIVE To detect the expression profile of bladder cancer and to delineate the interaction network of these genes in invasive bladder cancer. METHODS A total of 126 differentially expressed genes were identified, and input into STRING online database to delineate interaction network. The network data were screened with central nodes. The expression of genes with the most evident change in the exfoliated cells of urine was detected. RNA markers with over-expression in stage Ta tumor and/or T1 to T4 tumors but low expression in blood or inflammatory cells were characterized. RESULTS On the basis of assay of 21,639 whole-genome oligonucleotide microarray, a total of 126 differentially expressed genes were identified, of which 69 had up-regulated expression and 57 had down-regulated expression. STRING screening showed there were interactions among 103 genes in the bladder cancer which formed a complex network. A total of 23 central nodes were screened with Cytoscape and are involved in multiple signaling pathways related to tumorigenesis. The test specificity was 80% for the 30 control patients with urinary tract infections. The combination of BLCA-4 and HOXA13 could distinguish between low and high grade tumors, with specificity and sensitivity of 80%. CONCLUSION The interaction network of differentially expressed genes, especially the central nodes of this network, can provide evidence for the early diagnosis and molecular targeted therapy of invasive bladder cancer, and combined detection of IGF-1, hTERT, BLCA-4 and HOXA13 genes is helpful to evaluate BTCC at different stages.

Luo H, Zhao X, Wan X, Huang S, Wu D. Gene microarray analysis of the lncRNA expression profile in human urothelial carcinoma of the bladder. Int J Clin Exp Med 2014; 7:1244-54. [PMID: 24995079 PMCID: PMC4073740] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2014] [Accepted: 05/11/2014] [Indexed: 06/03/2023]
Abstract
OBJECTIVE To analyze the expression profile variation of lncRNAs in normal urinary bladder tissue and urothelial carcinoma of the urinary bladder through microarray technology. The differentially expressed lncRNAs were identified and classified, and their biological information was analyzed. The data obtained in the study will prove helpful for the diagnosis, treatment, and prevention of urothelial carcinoma of the bladder. MATERIALS AND METHODS Three specimens of urothelial carcinoma of the bladder and three specimens of normal bladder tissue were identified by histology. The total RNA was isolated from the bladder urothelial carcinomas and normal tissue and purified. The targets were mixed and hybridized with the genes on the microarray, which contained thirty thousand lncRNAs. The bladder urothelial carcinomas were then compared with the normal bladder tissue. The lncRNAs that were differentially expressed between the two groups were identified based on the signal-to-noise ratios using the Agilent Feature Extraction software and were analyzed with the Agilent Genespring GX software (Agilent). The outcome was obtained, and the biological information of these genes was deposited in GenBank. RESULTS The expression profile of lncRNAs was significantly different between normal bladder tissue and urothelial carcinoma of the bladder. Compared with normal bladder tissue, 1,122 lncRNAs exhibited at least a twofold, significant difference (P < 0.05) and are thus regarded as differentially expressed lncRNAs. Of these, 734 and 388 lncRNAs were upregulated and down regulated. The differentially expressed lncRNAs in the urothelial carcinoma of the bladder are distributed on every chromosome, and most of these lncRNAs are distributed on chromosomes 1, 2, 3, 4, 6, and X. CONCLUSIONS Urothelial carcinoma of the bladder is a complicated disease that involves the regulation of multiple genes and the participation of multiple chromosomes. Some of the differentially expressed lncRNAs that were upregulated, such as AK124776, lincRNA-RAB12-1, KRT8P25, RP11-474J18.4, AC000110.1, KRT8P13, KRT8P10, BC072678, and downregulated, such as nc-HOXB9-206, RP11-160A10.2, nc-HOXA11-86, nc-HOXD10-7, nc-HOXB9-205, CES4, nc-HOXD12-3, systematic research on these lncRNAs will help clarify the mechanisms of urothelial carcinoma of the bladder and guide the early diagnosis and treatment of this cancer in the future.

Abstract
Urothelial bladder cancer is the fourth most prevalent male malignancy in the United States and also one of the ten most lethal. Superficial or non-muscle-invasive bladder cancer has a high rate of recurrence and can progress to muscle invasive disease. Conventional surveillance requires regular cystoscopy and is used often with urinary cytology. Unfortunately, the cystoscopy procedure is invasive for patients and costly for health care providers. Urinary biomarkers have the potential to improve bladder cancer diagnosis, the efficiency and also the cost-effectiveness of follow up. It may also be possible for urinary biomarkers to help prognosticate particularly for patients with high-grade bladder cancer who may want enhanced assessment of their risk of disease progression. In this review the important historical urinary biomarkers and the newly emerging biomarkers are discussed. As will be presented, although many of the tests have good performance characteristics, unfortunately no single test can fulfill all the roles currently provided by cystoscopy and cytology. It is likely that in the future, urinary biomarker testing will be used selectively in a personalized manner to try and improve prognostication or reduce the necessity for invasive cystoscopy in patients understanding the limits of the test.
