Internal m^(6)A and m^(7)G RNA modifications in hematopoietic system and acute myeloid leukemiaOACSTPCDMEDLINE
Epitranscriptomics focuses on the RNA-modification-mediated post-transcriptional regulation of gene expression.The past decade has witnessed tremendous progress in our understanding of the landscapes and biological functions of RNA modifications,as prompted by the emergence of potent analytical approaches.The hematopoietic system provides a lifelong supply of blood cells,and gene expression is tightly controlled during the differentiation of hematopoietic stem cells(HSCs).The dysregulation of gene expression during hematopoiesis may lead to severe disorders,including acute myeloid leukemia(AML).Emerging evidence supports the involvement of the mRNA modification system in normal hematopoiesis and AML pathogenesis,which has led to the development of small-molecule inhibitors that target N6-methyladenosine(m^(6)A)modification machinery as treatments.Here,we summarize the latest findings and our most up-to-date information on the roles of m^(6)A and N7-methylguanine in both physiological and pathological conditions in the hematopoietic system.Furthermore,we will discuss the therapeutic potential and limitations of cancer treatments targeting m^(6)A.
