Modelling bladder cancer in mice: opportunities and challenges

Area of Science:

• Oncology
• Translational Medicine
• Animal Models

Background:

• Bladder cancer prognosis and treatment have seen minimal advancement over the last two decades.
• Bladder cancer presents a significant health burden, characterized by its debilitating nature, high fatality rate, and substantial treatment costs.
• Current research is hampered by a scarcity of effective mouse models, particularly those that accurately replicate invasive cancer phenotypes.

Purpose of the Study:

• To review the current state of mouse models for bladder cancer.
• To identify opportunities for developing more informative and predictive preclinical models.
• To facilitate progress in understanding bladder cancer progression, diagnosis, and treatment.

Main Methods:

• Comprehensive literature review of existing bladder cancer mouse models.
• Analysis of the limitations of current models in recapitulating human disease.
• Identification of key areas for improvement in model generation and characterization.

Main Results:

• Few existing mouse models adequately represent the complexity of human bladder cancer, especially invasive stages.
• Significant gaps exist in the utility of current models for studying disease progression and therapeutic response.
• There is a clear need for novel models that better mimic the heterogeneity and invasiveness of human bladder tumors.

Conclusions:

• Enhancing the development and application of bladder cancer mouse models is critical for future research.
• Improved models hold the potential to accelerate the discovery of novel diagnostic markers and therapeutic interventions.
• Strategic investment in creating and validating advanced mouse models is essential to overcome current research stagnation.
