摘要The m6A modification has been implicated as an important epitranscriptomic marker, which plays extensive roles in the regulation of transcript stability,splicing,translation,and local-ization. Nevertheless, only some genes are repeatedly modified across various conditions and the principle of m6A regulation remains elusive. In this study, we performed a systems-level analysis of human genes frequently regulated by m6A modification(m6Afreq genes)and those occasionally regulated by m6A modification (m6Aocca genes). Compared to the m6Aocca genes, the m6Afreq genes exhibit gene importance-related features, such as lower dN/dS ratio, higher protein-protein interaction network degree, and reduced tissue expression specificity. Signaling network analysis indicates that the m6Afreq genes are associated with downstream components of signaling cascades, high-linked signaling adaptors, and specific network motifs like incoherent feed forward loops. Moreover,functional enrichment analysis indicates significant overlaps between the m6Afreq genes and genes involved in various layers of gene expression,such as being the microRNA targets and the regulators of RNA processing.Therefore,our findings suggest the potential interplay between m6A epitranscriptomic regulation and other gene expression regulatory machineries.
