Copper-based architectures for bladder cancer therapy: mechanistic insights, progress and prospects

Area of Science:

• Biomedical Engineering
• Nanomedicine
• Oncology

Background:

• Bladder cancer presents significant challenges due to high recurrence, chemoresistance, and poor immunotherapy outcomes.
• Copper metabolism is increasingly recognized for its role in cancer progression and therapeutic vulnerabilities.
• Cuproptosis, a copper-dependent cell death pathway, offers a novel target for cancer therapy.

Purpose of the Study:

• To systematically review copper metabolism dysregulation in bladder cancer.
• To analyze the therapeutic potential of copper-based nanomaterials for bladder cancer treatment.
• To identify challenges and future directions for clinical translation of these nanomedicines.

Main Methods:

• Systematic review of literature on copper metabolism and nanomaterials in bladder cancer.
• Classification of copper-based nanomaterial categories (metallic Cu, polymers, compounds, composites).
• Analysis of synthesis, properties, and therapeutic applications of these nanomaterials.

Main Results:

• Copper dysregulation contributes to oxidative stress, ferroptosis, and cuproptosis in bladder cancer.
• Four main categories of copper-based nanomaterials demonstrate potential for synergistic therapies (photothermal, photodynamic, chemo-, immunotherapy).
• Key barriers to clinical translation include safety, pharmacokinetics, targeting, immune response, and regulatory issues.

Conclusions:

• Copper-based nanomedicines offer a promising strategy for precision intravesical therapy in bladder cancer.
• Addressing clinical translation barriers is crucial for realizing the full therapeutic potential.
• Future research should focus on physics-informed design, biomarker stratification, and integrated monitoring.
