Type:
Glycolysis is a metabolic pathway that converts glucose into pyruvate, producing a small amount of ATP (energy) in the process. It is a fundamental process for cellular energy production and occurs in the cytoplasm of cells. In normal cells, glycolysis is tightly regulated and is followed by aerobic respiration in the presence of oxygen, which allows for the efficient production of ATP.
In cancer cells, however, glycolysis is often upregulated, even in the presence of oxygen. This phenomenon is known as the Warburg Mutations in oncogenes (like MYC) and tumor suppressor genes (like TP53) can alter metabolic pathways, promoting glycolysis and other anabolic processes that support cell growth.effect.
Acidosis: The increased production of lactate from glycolysis can lead to an acidic microenvironment, which may promote tumor invasion and suppress immune responses.

Glycolysis is a hallmark of malignancy transformation in solid tumor, and LDH is the key enzyme involved in glycolysis.
