Abstract: The transcription factor c-Myc regulates the proliferation, differentiation, metabolism and other key processes of normal cells extensively.The unleashed MYC oncogene frequently produces abundant c-Myc protein, which directly regulates the gene expression of key metabolic enzymes, or tumor-related metabolic pathways by inhibiting microRNA, leading to abnormal metabolism characterized by heightened nutrients uptake, enhanced glycolysis and glutaminolysis, and elevated fatty acid and nucleotide synthesis.This paper briefly summarizes how c-Myc regulated metabolism on glycolysis, glutamine metabolism, tricarboxylic acid cycle, lipid metabolism and nucleotide synthesis in cancer cell,which provides some theoretical reference for the development of antitumor targets and drugs involving c-Myc.
