Article Synopsis
  • The study investigates the distal excretory component of the urinary tract in zebrafish, which has similarities to human urinary structures and is linked to various diseases.
  • Researchers identified and explored key genes related to the urinary system, confirming the expression of uroplakin genes in the zebrafish's urinary bladder and its development.
  • The findings suggest that zebrafish possess a functional urinary bladder and urethral opening, making them a suitable model for studying urinary tract diseases and disorders.

Context: Bladder cancer (BC) is common worldwide and poses a significant public health challenge. External risk factors and the wider exposome (totality of exposure from external and internal factors) contribute significantly to the development of BC. Therefore, establishing a clear understanding of these risk factors is the key to prevention.

Context: Men of African ancestry have demonstrated markedly higher rates of prostate cancer mortality than men of other races and ethnicities around the world. In fact, the highest rates of prostate cancer mortality worldwide are found in the Caribbean and Sub-Saharan West Africa, and among men of African descent in the USA. Addressing this inequity in prostate cancer care and outcomes requires a focused research approach that creates durable solutions to address the structural, social, environmental, and health factors that create racial disparities in care and outcomes.

Introduction: The European Organization for Research and Treatment of Cancer (EORTC) and the Spanish Urological Club for Oncological Treatment (CUETO) scoring systems show limited accuracy for the prediction of disease recurrence and progression of non-muscle-invasive bladder cancer (NMIBC). This aspect is even more relevant in the category of HR NMIBC. Biomarkers might potentially help to further categorize the outcomes of these patients.

Metastatic castration-resistant prostate cancer has poor survival outcomes. New prognostic gene panels are being used in developing ways to interrogate the likely natural history of an individual's disease. Biomarker innovations to calculate tumour burden also hold promise for the future, but there is still some way to go to validate and stratify their use.
