AI Article Synopsis
- Researchers found that high levels of a protein called HMMR could lead to worse outcomes for people with a type of bladder cancer.
- In their study, they looked at how HMMR is controlled in cancer cells and discovered that another protein, FOXM1, helps turn on HMMR.
- They also learned that blocking HMMR made cancer cells grow less and invade other tissues, which shows how important the FOXM1-HMMR connection is in bladder cancer progression.
Article Abstract
Our previous that HMMR upregulation independently predicts poor survival in patients with papillary muscle-invasive bladder cancer (MIBC). In this study, we explored its downstream regulations and the potential transcriptional factors activating its expression. MIBC derived T24 cells, and non-MIBC (NMIBC) derived RT4 cells were used for in vitro and in vivo studies. HMMR expression enhanced cell proliferation, the expression of mesenchymal markers, and cell invasion. It induced the nuclear entry of β-catenin, increased its active form in the nuclear part, and elevated the relative TOP/FOP activity. The promoter region of HMMR has a canonical FKH motif. FOXM1 bound to this site and activated HMMR transcription. HMMR knockdown significantly weakened FOXM1 overexpression induced bladder cancer growth, invasion, partial epithelial-to-mesenchymal transition (pEMT), as well as the activation of the Wnt/β-catenin signaling pathway. In conclusion, the findings in this study expanded our understanding of the mechanisms underlying HMMR dysregulation and the functional role of the FOXM1-HMMR axis in bladder cancer.

Long-term Outcomes of Prostate Capsule-Sparing and Nerve-Sparing Radical Cystectomy With Neobladder: A Propensity Score-Matched Comparison.
Int Neurourol J
December 2024
Department of Urology, Jinhua Hospital Affiliated to Zhejiang University School of Medicine, Jinhua, China.
Purpose: This study aimed to compare and analyze the feasibility and long-term efficacy of prostatic capsule-sparing (PCS) and nerve-sparing (NS) radical cystectomy in the treatment of bladder cancer.
Methods: From June 2004 to December 2021, our institution treated and followed 145 patients who underwent radical cystectomy with neobladder reconstruction for over a year. These patients were divided into 2 groups: PCS (n=74) and NS (n=71).

Hedyotis diffusa Willd. (HDW), a traditional Chinese medicinal plant, exhibits a variety of pharmacological effects and has anticancer potential for a wide range of cancer types; Ferroptosis is a non-apoptosis-regulated cell death induced by iron accumulation and subsequent lipid peroxidation; and there is currently an increasing interest in the therapeutic role of ferroptosis in cancer. However, the effects of HDW on bladder cancer and its underlying molecular mechanisms remain largely unknown.

Advanced urothelial carcinoma (aUC) has a dismal prognosis, with a 5-year survival rate of approximately 10%. Platinum-based chemotherapy has been the backbone of the first-line treatment of aUC for over 40 years. Only in the last decade, the treatment of aUC has evolved and been enriched with new classes of drugs that demonstrated pivotal improvements in terms of oncological responses and, ultimately, survival.

Introduction: We evaluated the prognostic potential of the Beta-human chorionic gonadotropin (β-hCG), Carbohydrate Antigen 19-9 (CA19-9), Cancer Antigen 125 (CA125), and Carcinoembryonic Antigen (CEA) tumor markers for bladder cancer.
Methods: We analyzed the records of 369 patients who underwent radical cystectomy for urothelial cancer (UC) between October 2012 until December 2019. Levels of CA19-9, CA125, CEA, and β-hCG before radical cystectomy were measured in all patient samples, and serum biomarker cutoff values were used as normal and elevated values.
