N6-methyladenosine (m⁶A) has been identified in various biological processes and plays important regulatory functions in diverse cells. However, there is still no visualization database for exploring global m⁶A patterns across cell lines. Here we collected all available MeRIP-Seq and m⁶A-CLIP-Seq datasets from public databases and identified 340,950 and 179,201 m⁶A peaks dependent on 23 human and eight mouse cell lines respectively. Those m⁶A peaks were further classified into mRNA and lncRNA groups. To better understand the potential function of m⁶A, we then mapped m⁶A peaks in different subcellular components and gene regions. Among those human m⁶A modification, 190,050 and 150,900 peaks were identified in cancer and non-cancer cells, respectively. Finally, all results were integrated and imported into a visualized cell-dependent m⁶A database CVm6A. We believe the specificity of CVm6A could significantly contribute to the research for the function and regulation of cell-dependent m⁶A modification in disease and development.
