FTO demethyltion of N6-methyladenosine depends on the RRACH motif [m6A-seq]

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.

YTHDF3 improves translation initiation of mRNAs with N6-methyladenosine methylation at 5’ untranslated region by facilitating eIF2AK2 recruitment in oxaliplatin-resistant colorectal cancer - RIP-seq dataset

Project description:Oxaliplatin as a first-line drug frequently causes the chemo-resistance on colorectal cancer (CRC). N6-methyladenosine (m6A) methylation has been largely acknowledged in multiple biological functions. However, the molecular mechanisms underlying the m6A methylation in modulating anticancer drug resistance in CRC are still obscure. In present study, RIP-seq was conducted to investigate the occupancy of N6-methyladenosine RNA binding protein 3 (YTHDF3) served as “readers” that can recognize m6A modification site in HCT116 cells with oxaliplatin resistance (HCT116R). Then, YTHDF3 was knockdown by siRNA in HCT116 cells with oxaliplatin resistance, and RIP-seq was further conducted to investigate m6A methylation of HCT116, HCT116R and HCT116R cells with YTHDF3 knockdown.

FTO suppresses cardiac fibrosis after myocardial infarction via m6A-mediated epigenetic modification [MeRIP-seq]

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.

Knock down of FTO in cervical cancer cells

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.

FTO-Dependent m6A Regulates Cardiac Function During Remodeling and Repair

Project description:Background: Despite its functional importance in various fundamental bioprocesses, the studies of N6-methyladenosine (m6A) in the heart are lacking. Methods: We performed methylated (m6A) RNA immunoprecipitation sequencing (MeRIP-seq) to map transcriptome-wide m6A in healthy and failing hearts. Results: Improving expression of FTO in failing mouse hearts attenuated the ischemia-induced increase in m6A and decrease in cardiac contractile function. This is carried out by the demethylation activity of FTO, which selectively demethylates cardiac contractile transcripts Conclusion: Collectively, our study demonstrates the functional importance of FTO-dependent cardiac m6A methylome in cardiac contraction during heart failure and provides a novel mechanistic insight into the therapeutic mechanisms of FTO.

Recruitment of the m6A/Am demethylase FTO to target RNAs by the telomeric zinc finger protein ZBTB48 [ChIP-seq]

Project description:Fat mass and obesity-associated protein (FTO) can remove both the N6-methyladenosine (m6A) and N6, 2′-O-dimethyladenosine (m6Am) methylation marks that function in multiple aspects of posttranscriptional regulation. Here, we demonstrate that Zbtb48, a C2H2-zinc finger protein that functions in telomere maintenance, associates with FTO and binds both mRNA and the telomere-associated regulatory RNA TERRA to regulate the functional interactions of FTO with target transcripts. Specifically, depletion of Zbtb48 affects targeting of FTO to sites of m6A/m6Am modification, changes cellular m6A/m6Am levels and, consequently, alters decay rates of target RNAs. Zbtb48 ablation also accelerates growth of HCT-116 colorectal cancer cells and modulates FTO-dependent regulation of Metastasis-associated protein 1 (MTA1) transcripts by controlling the binding to MTA1 mRNA of the m6A reader IGF2BP2. Our findings thus uncover a previously unknown mechanism of posttranscriptional regulation in which Zbtb48 co-ordinates RNA-binding of the m6A/m6Am demethylase FTO to control expression of its target RNAs.
