The methylation of adenosine in RNA to N6-methyladenosine (m(6)A) is involved in the regulation of metabolism in cancer cells. Dysregulation of m(6)A modification may lead to abnormalities in glucose, lipid, amino acid metabolism, and other metabolites, which can contribute to increased cell proliferation, tumor initiation, and metastasis. Understanding the role of m(6)A modification in metabolic reprogramming provides potential targets for cancer therapy and early detection.
Methylation of adenosine in RNA to N6-methyladenosine (m(6)A) is widespread in eukaryotic cells with his integral RNA regulation. This dynamic process is regulated by methylases (editors/writers), demethylases (remover/erasers), and proteins that recognize methylation (effectors/readers). It is now evident that m(6)A is involved in the proliferation and metastasis of cancer cells, for instance, altering cancer cell metabolism. Thus, determining how m(6)A dysregulates metabolic pathways could provide potential targets for cancer therapy or early diagnosis. This review focuses on the link between the m(6)A modification and the reprogramming of metabolism in cancer. We hypothesize that m(6)A modification could dysregulate the expression of glucose, lipid, amino acid metabolism, and other metabolites or building blocks of cells by adaptation to the hypoxic tumor microenvironment, an increase in glycolysis, mitochondrial dysfunction, and abnormal expression of metabolic enzymes, metabolic receptors, transcription factors as well as oncogenic signaling pathways in both hematological malignancies and solid tumors. These metabolism abnormalities caused by m(6)A's modification may affect the metabolic reprogramming of cancer cells and then increase cell proliferation, tumor initiation, and metastasis. We conclude that focusing on m(6)A could provide new directions in searching for novel therapeutic and diagnostic targets for the early detection and treatment of many cancers.
