MetabolomicsGut Commensal Bacteria-Derived Methionine is Required for Host Reproduction by Modulating RNA m6A Methylation of the Insulin Receptor_targeted metabolites

Gut commensal bacteria promote host reproduction by modulating metabolism and nutrition, but the molecular mechanisms by which microbes regulate reproduction remain unclear. Here, we show that gut commensal bacteria promote host reproduction by providing amino-acid methionine, which controls the ...

MetabolomicsSystemic Inflammation Induces Cholestasis via Upregulating a Short Variant of FTO to Remove the m6A Methylation in the 3’-UTR of Cyp7b1 mRNAs in liver
The cholestasis frequently occurs in patients with inflammatory processes. However, the mechanisms of inflammation in inducing cholestasis are still unclear. Here, by using lipopolysaccharide (LPS)-induced cholestasis mouse models, we found that most genes encoding enzymes responsible for bile acid ...

MetabolomicsN6-methyladenosine modification is not a general trait of positive-sense RNA viral genomes

Despite the nuclear localization of the m6A machinery, the genomes of multiple exclusively-cytoplasmic RNA viruses, such as chikungunya (CHIKV) and dengue (DENV), are reported to be extensively m6A-modified. However, these findings are mostly based on m6A-seq, an antibody-dependent technique with...

Transcriptomicsm6A RNA Methylation Is Regulated by MicroRNAs and Promotes Reprogramming to Pluripotency
N6-methyladenosine (m6A) has been recently identified as a conserved epitranscriptomic modification of eukaryotic mRNAs, but its features, regulatory mechanisms, and functions in cell reprogramming are largely unknown. Here, we report m6A modification profiles in the mRNA transcriptomes of four cell...

Transcriptomicsm6A mapping in human RNA (untreated)
We developed a novel approach, m6A-seq, for high-resolution mapping of the transcriptome-wide m6A landscape, based on antibody-mediated capture followed by massively parallel sequencing. Identification of m6A modified sequences in HepG2 cells.

TranscriptomicsPlacental epitranscriptome-wide analysis of revealed the m6A modification level at 5’ UTR related fetal growth
To further understand the relationship between the level of gene expression and protein translation in human placenta, we focused on N6-methyladenosine: m6A, which is a methylation modification of mRNA acting as a post-transcriptional regulation which has drawn attention in recent years. It is said ...

TranscriptomicsProfiling of N6-Adenosine (m6A) Methylation in Arabidopsis thaliana wild-type and fip37-4 LEC1:FIP37
N6-methyladenosine (m6A) represents the most prevalent internal modification on messenger RNA, and requires a multicomponent m6A methyltransferase complex in mammals. How their plant counterparts determine the global m6A modification landscape and its molecular link to plant development remain elusi...

Transcriptomicsm6A RNA methylation promotes XIST-mediated transcriptional repression
XIST is a long non-coding RNA (lncRNA) that mediates transcriptional silencing of X chromosome genes. Here we show that XIST is highly methylated with at least 78 N6-methyladenosine (m6A) residues, a reversible base modification whose function in lncRNAs is unknown. We show that m6A formation in XIS...

TranscriptomicsWidespread Occurrence of m6A in bacterial mRNA
N6-methyladenosine (m6A) is one of the most abundant modifications in eukaryotic RNA. Recent mapping of m6A methylomes in mammals, yeast, and plants as well as characterization of m6A methyltransferases, demethylases, and binding proteins have revealed regulatory functions of this dynamic RNA modifi...
