Abstract
<h4>Background</h4>Compared with the well-studied 5-methylcytosine (m<sup>5</sup>C) in DNA, the role and topology of epitranscriptome m<sup>5</sup>C remain insufficiently characterized.<h4>Results</h4>Through analyzing transcriptome-wide m<sup>5</sup>C distribution in human and mouse, we show that the m<sup>5</sup>C modification is significantly enriched at 5' untranslated regions (5'UTRs) of mRNA in human and mouse. With a comparative analysis of the mRNA and DNA methylome, we demonstrate that, like DNA methylation, transcriptome m<sup>5</sup>C methylation exhibits a strong clustering effect. Surprisingly, an inverse correlation between mRNA and DNA m<sup>5</sup>C methylation is observed at CpG sites. Further analysis reveals that RNA m<sup>5</sup>C methylation level is positively correlated with both RNA expression and RNA half-life. We also observed that the methylation level of mitochondrial RNAs is significantly higher than RNAs transcribed from the nuclear genome.<h4>Conclusions</h4>This study provides an in-depth topological characterization of transcriptome-wide m<sup>5</sup>C modification by associating RNA m<sup>5</sup>C methylation patterns with transcriptional expression, DNA methylations, RNA stabilities, and mitochondrial genome.
