Roles and implications of mRNA N ⁶ ‐methyladenosine in cancer

RNA N 6 ‐methyladenosine modification is the most prevalent internal modification of eukaryotic RNAs and has emerged as a novel field of RNA epigenetics, garnering increased attention. To date, m 6 A modification has been shown to impact multiple RNA metabolic processes and play a vital role in numerous biological processes. Recent evidence suggests that aberrant m 6 A modification is a hallmark of cancer, and it plays a critical role in cancer development and progression through multiple mechanisms. Here, we review the biological functions of mRNA m 6 A modification in various types of cancers, with a particular focus on metabolic reprogramming, programmed cell death and tumor metastasis. Furthermore, we discuss the potential of targeting m 6 A modification or its regulatory proteins as a novel approach of cancer therapy and the progress of research on m 6 A modification in tumor immunity and immunotherapy. Finally, we summarize the development of different m 6 A detection methods and their advantages and disadvantages.
