ObjectiveTo summarize the latest research progress of autophagy on regulation of tumor energy metabolism. MethodThe latest research progresses of the regulation mechanism of autophagy on the energy metabolism of tumor cells and the influence on the biologic behavior of tumor in recent years were reviewed. ResultThe autophagy could affect the biological behavior of the tumor by influence of the tumor cell glucose uptake, glycolysis, oxidative phosphorylation, lipid metabolism, and amino acid metabolism. ConclusionsThe regulation of autophagy on tumor energy metabolism provides a theoretical basis for the survival mechanism of tumor under the stress condition. What's more, to research the mechanism of autophagy on regulation of energy metabolism and the effect on tumor biologic behavior will contribute to the development of new and more effective personalized anticancer therapy. As far as the research progress about tumor cells energy metabolism regulated by autophagy, what we must be revealed is whether other factors including oncogene, anti-oncogene, and signaling pathways take part in this regulation and what influence would be on the biological behavior of different tumors.
