Multiobjective optimization based-approach for discovering novel cancer therapies

Area of Science:

• Oncology
• Computational Biology
• Biomedical Engineering

Background:

• Solid tumors require new blood vessel formation (angiogenesis) for growth and survival.
• Inhibiting tumor angiogenesis is a key strategy in cancer therapy.
• Current anti-angiogenesis therapies, like blocking VEGF, are effective but limited by complexity.

Purpose of the Study:

• To develop a high-fidelity simulation of angiogenesis.
• To utilize a search-based approach for discovering novel cancer treatments targeting angiogenesis.
• To optimize interventions by balancing development cost and simulated tumor oxygenation.

Main Methods:

• Development of a sophisticated angiogenesis simulation model.
• Application of a parallel search-based algorithm for drug discovery.
• Multiobjective combinatorial optimization to identify effective anti-angiogenic strategies.

Main Results:

• The search process successfully identified known anti-angiogenic interventions.
• Novel, nonintuitive therapeutic approaches for inhibiting blood vessel growth were discovered.
• The simulation-based approach proved effective in uncovering new treatment possibilities.

Conclusions:

• A computational approach using high-fidelity angiogenesis simulation can accelerate the discovery of cancer therapies.
• Optimizing interventions based on cost and efficacy provides a powerful framework for identifying novel treatments.
• This method holds promise for uncovering nonintuitive yet effective strategies against tumor angiogenesis.
