Dissecting Cancer Metabolism and Therapeutic Resistance Using In Vitro Platforms

Area of Science:

• Oncology
• Cancer Biology
• Biotechnology

Background:

• Understanding cancer metabolism is crucial for developing new therapies.
• In vitro models are essential for studying tumor biology and metabolism-based treatments.

Purpose of the Study:

• To compare the utility of 2D and 3D in vitro models in cancer metabolism research.
• To highlight the complementary roles of 2D and 3D models in advancing precision oncology.

Main Methods:

• Utilized traditional 2D monolayer cultures for mechanistic studies and drug screening.
• Employed advanced 3D models (spheroids, organoids, tumor-on-a-chip) to mimic in vivo tumor conditions.
• Conducted comparative analyses of metabolic flux, drug response, and nutrient stress adaptation between 2D and 3D cultures.

Main Results:

• 2D models offer scalability and cost-effectiveness for early drug discovery.
• 3D models better recapitulate tumor heterogeneity, gradients, and stroma interactions, providing higher translational relevance.
• Significant differences observed in metabolic flux and drug response between 2D and 3D culture systems.

Conclusions:

• Integrated approaches using both 2D and 3D models are necessary for comprehensive cancer metabolism research.
• 3D platforms are valuable for validating metabolic vulnerabilities and therapeutic responses in physiologically relevant contexts.
• Complementary use of these models facilitates precision oncology, target identification, and personalized treatment strategies.
