Abstract

Xu et al. show that oligodendrocyte development is associated with dynamic changes in posttranscriptional mRNA methylation. Moreover, they demonstrate that the m6A epigenetic RNA mark has considerable impact on the myelinating cell's transcriptome and is essential for normal CNS myelination.
