Transcriptome-wide mapping of host mRNA m6A modification to decipher the role of gut microbiome
A recently layer of gene expression regulation is N6-methyladenosine (m6A) mRNA modification. The role of gut microbiota in modulating host m6A epitranscriptomic and gene expression has not been studied. To decipher the role of gut microbiome, we profiled m6A mRNA modification epitranscriptomic mark in conventional mice compared to germ free mice. Transcriptome-wide mapping of host m6A mRNA modifications in four mice tissues allowed us to discover that gut microbiota can greatly impact host m6A mRNA modifications. The expression levels of m6A writers in mice tissues are regulated by gut microbiota. In conclusion, we report transcriptome-wide mapping of host m6A mRNA modifications regulated by gut microbiota. The present study can help better understand the role of the microbiome in host gene expression and host-microbiome interactions. Overall design: The profiles of mRNA m6A modifications of four tissues from specific pathogen free mice and germ free mice are compared.
