Sugar Metabolism: A New Approach to Cancer Therapy

🍬Cancer cells exhibit the Warburg effect, consuming more sugar than normal cells.

⚡️PET imaging can diagnose cancer by detecting the concentration of radioactively-labeled sugar in organs.

🔬Cancer cells metabolize sugar differently, generating less energy but supporting biosynthetic pathways for growth and division.

🧬Pyruvate kinase M2, altered in all cancer cells, plays a crucial role in cancer metabolism.

💡Understanding the complex metabolism of cancer cells opens new avenues for personalized cancer therapy.

What is the Warburg effect?

—The Warburg effect refers to the observation that cancer cells consume more sugar than normal cells.

How is the Warburg effect used for cancer diagnosis?

—PET imaging can detect cancer cells by measuring the concentration of radioactively-labeled sugar in organs.

How do cancer cells metabolize sugar differently?

—Cancer cells convert most sugar to lactate, even with sufficient oxygen, generating less energy but supporting biosynthetic pathways.

What is pyruvate kinase M2?

—Pyruvate kinase M2 is an enzyme altered in all cancer cells and plays a crucial role in cancer metabolism.

How does understanding cancer metabolism contribute to personalized therapy?

—By studying the altered metabolism of individual cancer cells, personalized therapy strategies can be developed to target specific metabolic pathways.
