RESUMEN
Reprogramming of metabolism is one of the most critical features in tumorigenesis and tumor growth. Many types of cancer show an increased demand for specific amino acids, rely on exogenous supplies, or alter amino acid metabolic pathways, leading to changes in corresponding amino acid levels to meet the need of tumorigenesis. Therefore, if the level of tumor growth-dependent amino acids can be effectively controlled, a new treatment strategy can be developed from the perspective of cell metabolism. At present, remarkable progress has been made in this field. This paper outlines the amino acid metabolic pathways closely related to tumorigenesis and tumor growth, and summarizes the corresponding regulatory mechanisms and active molecules. Finally, the direction of the field is discussed and prospected for future development.
