Warburg Effect

Category: mechanism

The observation that cancer cells preferentially use glycolysis for energy even in the presence of oxygen. Forms the basis for metabolic therapy approaches in oncology.

Mechanism Detail

Cancer cells upregulate glucose transporters (GLUT1, GLUT4) and glycolytic enzymes (hexokinase II, PKM2) to fuel rapid proliferation. This metabolic reprogramming generates biosynthetic intermediates for cell growth. Targeting the Warburg effect through glucose restriction (ketogenic diet), GLUT inhibition (fenbendazole), or metabolic enzyme modulation is an active research area.

Clinical Status

PET scanning exploits the Warburg effect (FDG uptake). Metabolic therapies (ketogenic diet + standard treatment) are in clinical trials for glioblastoma and other cancers. Press-pulse metabolic therapy is theoretical.
