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

Reading and writing of mRNA m6A modification orchestrate mouse maternal-to-zygotic transition

Project description:Background: Maternal and zygotic mRNAs play critical roles in maternal-to-zygotic transition (MZT) stage and N6-methyladenosine (m6A) has been proven as an important RNA metabolism regulation system. However, the dynamic profiles of m6A modification during mammalian MZT and its potential functions remain largely unknown. Results: Here we utilized m6A-seq, low-input RNA-seq, LiRibo-seq and low-input proteomic analysis to examine the mRNA regulation dynamics during mouse MZT. We found that m6A could be inherited from maternal origin or de novo added after fertilization. Interestingly, we observed the de novo m6A modification on mRNA during zygotic genome activation (ZGA), especially at major ZGA. Further analysis showed that m6A modification on maternal mRNAs not only correlates with mRNA degradation after fertilization, but also maintains the stability of a small group of mRNAs thereby promoting their translation after fertilization. Using CRISPR-Cas13d mediated RNA editing, we systemically evaluated the functions of ten m6A regulators and identified Ythdc1 and Ythdf2 as key m6A readers for mouse preimplantation development. By combining low-input RNA-seq, RNA immunoprecipitation (RIP) and qRT-PCR, we uncovered and verified that Ythdc1 can associate with a small group of m6A-tagged mRNAs and participate in their mRNA stability regulation. Conclusions: Our integrated multi-omic analysis links m6A modification to the diverse fates of maternal and zygotic mRNAs and establishes a key role of m6A mediated RNA metabolism in mammalian MZT.

Targeted RNA N6-Methyladenosine Demethylation Controls Cell Fate Transition in Human Pluripotent Stem Cells

Project description:Deficiency of the N6-methyladenosine (m6A) methyltransferase complex results in global reduction of m6A abundance and defective cell development in embryonic stem cells (ESCs). However, it’s unclear whether regional m6A methylation would affect cell fate decisions due to the inability to modulate individual m6A modification in ESCs with precise temporal control. Here, we develop a targeted RNA m6A erasure (TRME) system to achieve site-specific demethylation of RNAs in human ESCs (hESCs). TRME, in which a stably transfected, doxycycline-inducible dCas13a is fused to the catalytic domain of ALKBH5, can precisely and reversibly demethylate the targeted m6A site of mRNA and increase mRNA stability with limited off-target effects. We further demonstrate that temporal m6A erasure on a single site of SOX2 is sufficient to control the differentiation of hESCs. This study provides a versatile toolbox to reveal the function of individual m6A modification in hESCs, enabling cell fate control studies at the epitranscriptional level.

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.
