ABSTRACT=<p><bold>Aim:</bold> To identify the alterations of N6-methyladenosine (m<sup>6</sup>A) RNA profiles in cisplatin-induced acute kidney injury (Cis-AKI) in mice.</p><p><bold>Materials and Methods:</bold> The total level of m<sup>6</sup>A and the expression of methyltransferases and demethylases in the kidneys were measured. The profiles of methylated RNAs were determined by the microarray method. Bioinformatics analysis was performed to predict the functions.</p><p><bold>Results:</bold> Global m<sup>6</sup>A levels were increased after cisplatin treatment, accompanied by the alterations of Mettl3, Mettl14, Wtap, Fto, and Alkbh5. A total of 618 mRNAs and 98 lncRNAs were significantly differentially methylated in response to cisplatin treatment. Bioinformatics analysis indicated that the methylated mRNAs predominantly acted on the metabolic process.</p><p><bold>Conclusion:</bold> M<sup>6</sup>A epitranscriptome might be significantly altered in Cis-AKI, which is potentially implicated in the development of nephrotoxicity.</p>
