Glutamine metabolism plays a significant role in cancer biology, as many cancer cells exhibit altered metabolic pathways to support their rapid growth and proliferation.
Glutamine is a non-essential amino acid that serves as a vital nutrient for many cells, including cancer cells. It is involved in various metabolic processes, including protein synthesis, nucleotide synthesis, and energy production.
Warburg Effect: Cancer cells often rely on aerobic glycolysis (the Warburg effect) for energy production, even in the presence of oxygen. Glutamine metabolism can complement this process by providing intermediates for the tricarboxylic acid (TCA) cycle, which is crucial for energy production and biosynthesis.
Inhibitors of glutaminase (an enzyme that converts glutamine to glutamate) and other metabolic pathways are being explored in preclinical and clinical settings.
