In conclusion, the present study demonstrated that circRNAs were dysregulated in bladder cancer tissues compared with matched normal samples. Pathway analysis was also performed to predict the binding of miRNAs to the dysregulated circRNAs. The results revealed that hsa_circ_100242 may be involved in bladder cancer initiation and progression by sponging miR-145. These findings may provide further insights into the functional and therapeutic roles of circRNAs in bladder cancer. PMID: 32218853 [PubMed - as supplied by publisher]
In this study, the CIBERSORT algorithm was used to identify the immune cell infiltration signatures. The gene expression profiles, mutation data, and clinical data were collected from The Cancer Genome Atlas (TCGA) database. Unsupervised consensus clustering was used to acquire the immune cell infiltration subtypes of bladder cancer based on the fractions of 22 immune cell types. Four immune cell clusters with different immune infiltrate and mutation characteristics were identified. In addition, this stratification has a prognostic relevance, with cluster 2 having the best outcome, cluster 1 the worst. These clusters showe...

This study thoroughly analyzed E-cadherin and associated changes in BC, and reports Ephrin-B1 as a new marker of tumor aggressiveness.
In conclusion, our study indicated that CRYAB, CGNL1, ECM1, and GPX3 are potential urine biomarkers of HGBC. These four novel urine biomarkers will have attractive applications to provide new diagnostic methods, prognostic predictors and treatment targets for HGBC, which could improve the prognosis of HGBC patients, if validated by further experiments and larger prospective clinical trials.
For mixed population of patients with non –muscle‐invasive bladder who were treated with and without Bacillus Calmette‐Guerin and without any immediate postoperative chemotherapy, we show that European Organisation for Research and Treatment of Cancer scale provides the best recurrence and progression prediction in comparison with Eur opean Association of Urology and Club Urologico Espanol de Tratamiento Oncologico risk scores. We highlight the role of diameter and tumor extent in transition prediction. AbstractBrief Description: The results demonstrate that the European Organisation for Research and Treatment of...

Abstract Interest in nanostructures such as titanate nanotubes (TNT) has grown notably in recent years due to their biocompatibility and economic viability, making them promising for application in the biomedical field. Quercetin (Qc) has shown great potential as a chemopreventive agent and has been widely studied for the treatment of diseases such as bladder cancer. Motivated by the possibilities of developing a new hybrid nanostructure with potential in biomedical applications, this study aimed to investigate the incorporation of quercetin in sodium (NaTNT) and zinc (ZnTNT) titanate nanotubes, and characterize t...
In this study, we analyzed the tumor tissues of 224 patients with pTa, pT1, and pT2 urinary bladder cancer. We performed a histomorphologic analysis and immunohistochemistry for p53, Ki-67, and E-cadherin, which were selected as markers of the malignant process. For pTa and pT1, univariate analyses of cancer-specific survival (CSS), progression-free survival (PFS), and recurrence-free survival (RFS) were calculated using the Kaplan-Meier method, the log-rank test and Cox regression. Multivariate analysis was performed by a Cox regression analysis. Ki-67 (P
