Area of Science:

• Biochemistry
• Computational Biology
• Pharmacology

Background:

• Protein-metal interactions are crucial for anticancer metallodrug efficacy and pharmacokinetics.
• Traditional methods for studying these interactions are slow, expensive, and struggle with dynamic biological processes.
• Machine learning (ML) offers a promising alternative for understanding these complex mechanisms.

Purpose of the Study:

• To review the current state and challenges of applying ML to predict tumor protein-metal binding.
• To highlight the importance of high-quality, tumor-specific datasets and multimodal data integration.
• To discuss strategies for improving ML model interpretability in cancer research.

Main Methods:

• Summarizing recent advancements in ML for tumor protein-metal binding prediction.
• Presenting multimodal protein-metal binding datasets and preprocessing strategies.
• Reviewing methods for data modality integration and model interpretability.

Main Results:

• ML application in tumor protein-metal binding is limited by data scarcity, lack of multimodal data consideration, and model interpretability challenges.
• Multimodal datasets and integrated ML approaches show potential for improved predictions.
• Enhanced model interpretability is crucial for trustworthy decision-making in drug design.

Conclusions:

• Overcoming data limitations and enhancing ML interpretability are critical for advancing anticancer metallodrug development.
• Future research should focus on integrating protein-protein interaction data and predicting protein structural changes post-metal binding.
• ML holds significant promise for rational design of novel, effective metal-based cancer therapeutics.
