Oncometabolites in Cancer: Current Understanding and Challenges

Abstract Oncometabolites are pathognomonic hallmarks in human cancers, including glioma, leukemia, neuroendocrine tumors, and renal cancer. Oncometabolites are aberrantly accumulated from disrupted Krebs cycle and affect the catalytic activity of α-ketoglutarate–dependent dioxygenases. Oncometabolites indicate distinct cancer-related patterns ranging from oncogenesis and metabolism to therapeutic resistance. Here we discuss the current understanding of oncometabolites as well as the controversies and challenges associated with oncometabolite-driven cancers. New insights into the relationship between cancer and oncometabolites will elucidate novel therapeutic avenues for improved cancer treatment.
