m6A RNA modification controls cell fate transition in mammalian embryonic stem cells

Project description:N6-methyl-adenosine (m6A) is the most abundant modification on messenger RNAs and is linked to human diseases, but its functions in mammalian development are poorly understood. Here we reveal the evolutionary conservation and function of m6A by mapping the m6A methylome in mouse and human embryonic stem cells. Thousands of messenger and long noncoding RNAs show conserved m6A modification, including transcripts encoding core pluripotency transcription factors. m6A is enriched over 3M-bM-^@M-^Y untranslated regions at defined sequence motifs, and marks unstable transcripts, including transcripts turned over upon differentiation. Genetic inactivation or depletion of mouse and human Mettl3, one of the m6A methylases, led to m6A erasure on select target genes, prolonged Nanog expression upon differentiation, and impaired ESCM-bM-^@M-^Ys exit from self-renewal towards differentiation into several lineages in vitro and in vivo. Thus, m6A is a mark of transcriptome flexibility required for stem cells to differentiate to specific lineages. Examing m6A modification differences in two different cell types

m6A modification profile in primary microglia with/without Igf2bp1 knockdown

Project description:Our study demonstrated that the expression of Igf2bp1 in activated microglia was significantly up-regulated, implying a role of Igf2bp1 in LPS-induced m6A modifications in microglia. To understand the roles of Igf2bp1 on LPS-induced m6A modification in microglia, we performed Igf2bp1 loss-of-function (LOF) approach. Microglia stimulated by LPS were transfected with either scrambled siRNA control or Igf2bp1 siRNA for 48 hours. To m6A modification profiles in control and Igf2bp1 LOF microglia were determined by MeRIP-seq analysis.

Transcriptome profiling of m6A mRNA modification in inflammation of bovine mammary epithelial cells infected by Staphylococcus aureus and Escherichia coli

Project description:Mastitis is a common disease in dairy cows and brings massive losses to the dairy industry. m6A is a type of modification strongly associated with many diseases. However, the role of m6A in mastitis caused by Staphylococcus aureus and Escherichia coli has not been investigated.We used MeRIP-seq technology to sequence the bovine mammary epithelial cells (MAC-T) infected with inactivated S. aureus/E. coli for 24 h.

The m6A profile of mouse hypothalamic neural progenitor cells

Project description:m6A, the most prevalent internal modification on mRNAs, plays important roles in the nervous system. Whether neurogenesis in the hypothalamus, a region critical for controlling appetite, is regulated by m6A signaling, especially in humans, remains unclear. Here we showed that deletion of m6A writer Mettl14 in the mouse embryonic hypothalamus led to adult obesity, with impaired glucose-insulin homoeostasis and increased energy intake. Mechanistically, deletion of Mettl14 leads to hypothalamic arcuate nucleus neurogenesis deficits with reduced generation of feeding-related neurons and dysregulation of neurogenesis-related m6A-tagged transcripts. Deletion of m6A writer Mettl3, or m6A reader Ythdc1, shared similar phenotypes. METTL14 or YTHDC1 knockdown also led to reduced generation of feeding-related neurons in human brain subregion-specific arcuate nucleus organoids. Our studies reveal a conserved role of m6A signaling in arcuate nucleus neurogenesis in mice and human organoids and shed light on the developmental basis of epitranscriptomic regulation of food intake and energy homeostasis.
