Abstract Background: Many studies have evaluated the performance of fluorescence in situ hybridization (FISH) in detecting urothelial carcinoma, while few of them compared it in detecting bladder cancer (BC) vs. upper tract urothelial carcinoma (UTUC). This study aimed to determine and compare the FISH performance in detecting BC and UTUC. Methods: Data of patients with suspected urothelial carcinoma (UC) who accepted FISH from January 2021 to April 2023 were retrieved. The sensitivity and specificity of FISH in detecting BC and UTUC were determined and compared. Results: A total of 145 BC, 62 UTUC, and 170 non-UC patients were… More >

Abstract Objectives: Bladder Cancer (BC) is one of the most commonly diagnosed malignancies worldwide, with high rates of mortality and morbidity. It can be classified as non-muscle invasive bladder cancer (NMIBC) or muscle-invasive bladder cancer (MIBC), with radical cystectomy being the treatment for MIBC, which significantly reduces quality of life. MicroRNAs (miRs) act as critical genetic regulators, with both oncogenic and tumor-suppressive roles. MiR-10a is described as a tumor suppressor in various neoplasms, but its role in BC is controversial. This study aims to assess the activity of miR-10a in cellular invasion and proliferation in two… More >

Abstract Bladder cancer (BC) is one of the leading causes of cancer-related deaths in the world. Long noncoding RNA (lncRNA) taurine-upregulated gene 1 (TUG1) plays an important role in the development and progression of numerous cancers, including BC. However, the exact role of TUG1 in modulating BC progression is still poorly known. In this study, we found that TUG1 was upregulated and microRNA-29c (miR-29c) was downregulated in BC tissues and cell lines. Overexpression of TUG1 promoted the cell proliferation of T24 and EJ cells, whereas TUG1 knockdown had the opposite effect. Upregulation of TUG1 obviously facilitated… More >

Abstract 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. In addition, the in vivo experiment demonstrated that PDIA6 downregulation decreased the volume, weight, and metastasis More >
