AI Article Synopsis

  • The study explores the role of mitofusin-2 (MFN2), a mitochondrial GTPase, in bladder cancer by analyzing its expression in tumor and non-tumor tissues from patients.
  • MFN2 was found to be significantly downregulated in bladder cancer tissues and was associated with important clinical factors like tumor stage and patient survival.
  • Low levels of MFN2 increased cancer cell growth and invasion, suggesting that modulating MFN2 expression could help in treating bladder cancer.

Article Abstract

The present study aimed to investigate the biological role of the mitochondrial GTPase mitofusin-2 (MFN2) in bladder cancer. MFN2 mRNA expression in tumor and paired adjacent non-tumor tissues from 8 patients was investigated using reverse transcription-quantitative polymerase chain reaction analysis. Immunohistochemistry was used to investigate MFN2 expression in 117 bladder cancer specimens. The associations of MFN2 expression with clinicopathological parameters were evaluated statistically. In addition, the biological role of MFN2 in the proliferation, migration and invasion of bladder cancer cells was examined. It was identified that MFN2 expression was significantly downregulated in bladder cancer tissues compared with normal tissues. MFN2 expression was associated with tumor stage, tumor grade and lymph node status. Furthermore, patients with low MFN2 expression demonstrated a shorter overall survival time (P=0.025). MFN2 knockdown by small interfering RNA promoted cancer cell proliferation, migration and invasion , and enhanced tumor progression . Mechanistically, MFN2 was revealed to be involved in Wnt/β-catenin signaling. In conclusion, MFN2 may serve as a potential therapeutic target in the treatment of bladder cancer, and the progress of bladder cancer may be delayed by regulating MFN2 expression.

Bladder cancer (BLCA) genomic profiling has identified molecular subtypes with distinct clinical characteristics and variable sensitivities to frontline therapy. BLCAs can be categorized into luminal or basal subtypes based on their gene expression. We comprehensively characterized nine human BLCA cell lines (UC3, UC6, UC9, UC13, UC14, T24, SCaBER, RT4V6 and RT112) into molecular subtypes using orthotopic xenograft models.

Purpose: Transurethral resection of bladder tumor (TURBT) is the initial staging procedure for new bladder cancers (BCs). For muscle-invasive bladder cancers (MIBCs), TURBT may delay definitive treatment. We investigated whether definitive treatment can be expedited for MIBC using flexible cystoscopic biopsy and multiparametric magnetic resonance imaging (mpMRI) for initial staging.

Purposes: This study aimed to clarify the clinical outcomes of Bacillus Calmette-Guérin (BCG) treatment in patients with urothelial carcinoma (UC) of the prostatic urethra.

Methods: Between August 2003 and January 2023, 428 patients with non-muscle-invasive UC received BCG treatment (Tokyo strain, 80 mg, ≥ 5 times) in our hospital; 39 had UC of the prostatic urethra. We evaluated the cumulative incidence of intravesical recurrence, progression (muscle-invasive bladder cancer [MIBC] or metastasis), and subsequent radical cystectomy after BCG treatment in patients with UC of the prostatic urethra.

Identities of functional pSer/Thr.Pro protein substrates of the PIN1 prolyl isomerase and its effects on downstream signaling in bladder carcinogenesis remain largely unknown. Phenotypically, we found that PIN1 positively regulated bladder cancer cell proliferation, cell motility and urothelium clearance capacity in vitro and controlled tumor growth and potential metastasis in vivo.
