Project description:The fat mass and obesity-associated (FTO) protein is a well-characterized demethylase that removes N6-methyladenosine (m6A) from animal mRNAs. However, it is unclear yet how the demethylation operates in living cells. In this study, we applied genome-wide approaches to study how FTO finds its demethylation targets in human cells. We overexpressed FTO in human HeLa cells, demonstrating that FTO effectively removes m6A from the RRACH motif enriched in the 3’UTR regions and leaves m6A at other motifs unaffected. RRACH elements are clearly enriched at FTO binding sites; however, m6A has a lower tendency to be removed from the FTO-bound RRACH. Taken together with the experimental validaton results, we propose a model in which FTO effectivly recognizes m6A-containing RRACH motifs in RNAs, leading to a faster demethylation and dissociation kinetic than the association, and consequently undectable FTO-mRNA association. However, when FTO binds to the non-m6A RRACH motif, the binding has a lower dissociation kinetics, yielding the detectable FTO binding signals which would enable FTO to have roles in regulating other mRNA processing events.

Project description:FTO, an N6-methyladenosine (m6A) demethylase, can promote cervical cancer cell proliferation and migration. RNA-sequencing of SiHa cells with FTO knockdown was conducted to dissect the differentially expressed genes and the potential mechanism of FTO in cervical cancer.

Project description:N6-methyladenosine (m6A) is the most prevalent internal modification present in the mRNA of all higher eukaryotes. Here we present that m6A is selectively recognized by human YTH domain family (YTHDF2) protein to regulate mRNA degradation. By using crosslinking and immunoprecipitation, we have identified over 4000 substrate RNA of YTHDF2 with conserved core motif of G(m6A)C. We further estabilshed the role of YTHDF2 in RNA metabolism by a combination of ribosome profiling, RNA sequencing, m6A level quantification and cell-based imaging: the C-terminal domain of YTHDF2 selectively binds to m6A of mRNA and the N-terminal domain is responsive for localizing mRNA from translatable pool to processing body where mRNA decay occurs. PAR-CLIP and RIP was used to identify YTHDF2 binding sites followed by ribosome profling and RNA seq to assess the consequences of YTHDF2 siRNA knock-down

Project description:Cardiac fibrosis is common in cardiovascular diseases. N6-methyladenosine (m6A) is one of the most common modifications in eukaryotic mRNAs. Previous research has suggested that m6A modification is vital in cardiovascular diseases. The underlying targets of FTO were selected through transcriptome sequencing (RNA-seq) combined with methylated RNA immunoprecipitation sequencing (MeRIP-seq). According to MeRIP-seq and RNA-seq, FTO inhibited collagen synthesis in CFs.

Project description:We identified the major RNA binding protein-SFPQ as a direct interaction partner of FTO. Our study showed that FTO and SFPQ were located in close proximity throughout the transcriptome and overexpression of SFPQ led to the demethylation of adjacent N6-methyladenosine on RNA

Project description:The post-transcriptional modification of mRNA and tRNA provides an additional layer of regulatory complexity during gene expression. TRMT10A is a tRNA methyltransferase that installs N1-methylguanosine (m1G), while FTO performs demethylation on N6-methyladenosine (m6A) and N6,2'-O-dimethyladenosine (m6Am) in mRNA. We find that this tRNA methyltransferase TRMT10A interacts with mRNA demethylase FTO (ALKBH9), both in vitro and inside cells. Strikingly, depletion of TRMT10A not only led to decreased m1G in tRNA but also significantly increased m6A levels in mRNA. CLIP-seq results showed that TRMT10A shares a significant overlap of associated mRNAs with FTO, and these mRNAs have accelerated decay rates potentially through the regulation by specific m6A reader. Furthermore, transcripts with increased m6A upon TRMT10A ablation contain an overrepresentation of m1G9-containing tRNAs codons read by tRNAGln(TTG), tRNAArg(CCG), and tRNAThr(CGT). These findings collectively reveal the presence of coordinated mRNA and tRNA modifications and demonstrate a mechanism for regulating gene expression through the interactions between mRNA and tRNA modifying enzymes.
