Bladder Cancer (BC) presents one of the highest recurrence rates amongst solid tumours and constitutes the second deadliest disease of the genitourinary track. Non-invasive identification of patients facing disease recurrence and/or progression remains one of the most critical and challenging aspects in disease management. To contribute to this goal, we demonstrate the potential of glycan-affinity glycoproteomics nanoplatforms for urinary biomarkers discovery in bladder cancer. Briefly, magnetic nanoprobes (MNP) coated with three broad-spectrum lectins, namely Concanavalin A (ConA; MNP@ConA), Wheat Germ Agglutinin (WGA; MNP@WGA), and Sambucus nigra (SNA; MNP@SNA), were used to selectively capture glycoproteins from the urine of low-grade and high-grade non-muscle invasive as well as muscle-invasive BC patients...

Herein, we elucidated the molecular mechanisms and therapeutic potential of glutathione peroxidase 2 (GPX2) in bladder cancer. GPX2 expression gradually increased during progression from normal to papillary or nodular hyperplasia (PNHP) and urothelial carcinoma (UC) in a rat N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN)-induced bladder carcinogenesis model. GPX2 overexpression was more marked in UC with squamous differentiation (SqD) than in pure UC. Clinical intraepithelial lesions of papillary UC and invasive UC with SqD also had strong GPX2 expression in human radical cystectomy specimens...

The incidence and mortality rate of bladder cancer have dramatically expanded, so it's urgent to discover new biomarker and therapeutic target for bladder cancer. Recently, lncRNA has been identified as oncogene or tumor suppressor to regulate the tumorigenesis. LncRNA ZFAS1 has been confirmed as oncogene in various tumors. However, the expression, function, and underlying mechanism of ZFAS1 in bladder carcinogenesis have yet to be totally clarified. In the current study, our data demonstrated that ZFAS1 expression was significantly upregulated in bladder cancer tissues and cell lines...

Long noncoding RNAs (lncRNAs) have been identified to have more and more important roles in tumorigenesis and may be novel biomarker for cancer therapy. LncRNA TP73-AS1 is a novel identified lncRNA that has been demonstrated to be increased in several cancers, however, its function in bladder cancer remains unknown. The aim of this work was to examine the expression and role of lncRNA TP73-AS1 in bladder cancer. The expression levels of lncRNA TP73-AS1 in bladder cancer tissues and cell lines were determined by quantitative real-time PCR (qRT-PCR), and its clinical significance was assessed by statistical analysis...

With the discovery of new chemotherapeutic drugs, chemotherapy becomes increasingly valuable. However, the resistance of tumor cells to chemotherapeutic agents significantly limits the effectiveness and causes chemotherapy failure. MicroRNAs have been shown to regulate drug resistance in many types of cancer. In the present study, we measured the chemosensitivity of five bladder cancer (BCa) cell lines to seven commonly used chemotherapeutic drugs by Vita‑Blue assay. We then identified the most sensitive (5637) and most tolerant cell lines (H‑bc) and conducted a multi‑group test...

Bladder cancer is one of the most prevalent cancers worldwide. Unfortunately, there have been few advances in its clinical management due to a poor understanding of the correlations between its molecular and clinical features. Mounting evidence suggests that bladder cancer comprises a group of molecularly heterogeneous diseases that undergo a variety of clinical courses and possess diverse therapeutic responses. Owing to the close association between its molecular subtypes and clinicopathological features, specific therapeutic strategies have recently been suggested...

OBJECTIVES: To model the cost-effectiveness (CE) of a biomarker-based approach to select patients for neoadjuvant chemotherapy (NAC) prior to radical cystectomy (RC) in muscle-invasive bladder cancer (MIBC). MATERIALS AND METHODS: We obtained most recently clinical studies on locally-advanced bladder cancer treated by RC, including stage distributions, overall survival (OS) estimates, associated costs, and utilization/response to NAC. Additionally, we estimated the putative efficacy of 3 biomarkers to select patients for NAC: DNA repair gene panel [ATM, RB1, and FANCC], ERCC2, and RNA subtypes...

MicroRNAs (miRNAs) are implicated in the development of nearly all cancers and may function as promising biomarkers for early detection, diagnosis and prognosis. We sought to investigate the role of serum miRNAs as potential diagnostic biomarkers or biomarkers of risk for early-stage bladder cancer. First, we profiled global serum miRNAs in a pilot set of 10 non-muscle invasive bladder cancer (NMIBC) cases and 10 healthy controls matched on age, gender and smoking status. Eighty nine stably detectable miRNAs were selected for further testing and quantification by high-throughput Taqman analysis using the Fluidigm BioMark HD System to assess their association with NMIBC risk in both discovery and validation sets totaling 280 cases and 278 controls...

Non-coding RNAs (ncRNAs) are involved in the regulation of cell metabolism and neoplastic transformation. Recent studies have tried to clarify the significance of these information carriers in the genesis and progression of various cancers and their use as biomarkers for the disease; possible targets for the inhibition of growth and invasion by the neoplastic cells have been suggested. The significance of ncRNAs in lung cancer, bladder cancer, kidney cancer, and melanoma has been amply investigated with important results...

OBJECTIVES: Well differentiated keratinized squamous component as a part of urothelial carcinoma can be easily appreciated; however non-keratinizing squamous differentiation closely resembles urothelial differentiation. In addition prognostic significance of CK 5/6 expression in the absence of apparent squamous differentiation is still unclear. Therefore, in the present study we aimed to evaluate the frequency of CK 5/6 expression in 127 cases of urothelial carcinoma and its prognostic significance in loco-regional population...

In recent years, fundamental research has yielded new insights into tumour biology, and new treatments have been developed. This review highlights the role of the pathologist and how he can support clinicians to find the right treatment for each patient. We explain the problems of the molecular subgroups of bladder cancer, the role of neo-adjuvant chemotherapy in the context of these findings, and show the important role of checkpoint inhibitors. Furthermore we focus on kidney cancer, with the clear cell carcinoma as the most frequent tumour type...
