Analysis of m6A levels in K562 treted with the FTO inhibitor FB23-3 by m6A-mRNA&lncRNA Epitranscriptomic Microarray

Project description:FTO, an N6-methyladenosine demethylase, has emerged as a promising target for the treatment of specific acute myeloid leukemia (AML) subtypes. Here, we investigate the antiproliferative effects of the FTO inhibitor FB23-2 in leukemia. We demonstrate that FB23-2 potently inhibits proliferation across both AML and CML cell lines, irrespective of their responsiveness to FTO depletion. Interestingly, FB23-2 induces cell cycle arrest without a concurrent increase in m6A levels, suggesting an alternative mechanism of action.

Impact of gut microbiota on m6A/m epitranscriptomic mRNA modification in different host tissues

Project description:In this study we performed MeRIP-Seq to study N6-methyl adenosine (m6A) and and N6,2′ -O-dimethyladenosine (m6Am) modification of mRNA. We investigated the effect of the microbiota on the transcriptome and epitranscriptomic modifications in murine liver and cecum. We compared m6A/m modification profiles in cecum of conventionally raised (CONV) and germ-free (GF) mice. We additionally included GF mice colonised with the flora of CONV mice for four weeks (ex-GF), for which show that they exhibit similar patterns of the most abundant genera of gut bacteria as CONV mice. We added mice treated with several antibiotics to deplete the gut flora (abx)and vancomycin treated mice in which the genera Akkermansia, Escherichia/Shigella and Lactobacillus were enriched. Furthermore, we included GF mice colonised with the commensal bacterium Akkermansia muciniphila (Am), Lactobacillus plantarum (Lp) and Escherichia coli Nissle (Ec) and analysed their m6A/m modification profiles. In addition, we analysed changes in m6A/m- modified liver RNA for CONV, GF, and Am, Lp and Ec mice.

Targeted Quantitative Profiling of Epitranscriptomic Reader, Writer and Eraser Proteins Revealed Potential Crosstalk between N6-Methyladenosine and Other RNA Modifications

Project description:N⁶-methyladenosine (m6A) and its reader, writer, and eraser (RWE) proteins assume crucial roles in regulating the splicing, stability, and translation of mRNA. To our knowledge, no systematic investigations have been conducted about the crosstalk between m6A and other modified nucleosides in RNA. Herein, we modified our recently established liquid chromatography-parallel-reaction monitoring (LC-PRM) method by incorporating stable isotope-labeled (SIL) peptides as internal or surrogate standards for profiling epitranscriptomic RWE proteins. We were able to detect reproducibly a total of 114 RWE proteins in HEK293T cells with the genes encoding m6A eraser proteins (i.e., ALKBH5, FTO) and the catalytic subunit of the major m6A writer complex (i.e., METTL3) being individually ablated. Notably, eight proteins were altered by more than 1.5-fold in the opposite directions in HEK293T cells depleted of METTL3 and ALKBH5. Analysis of published m6A mapping results revealed the presence of m6A in the corresponding mRNAs of four of these proteins. Together, we integrated SIL peptides into our LC-PRM method for quantifying epitranscriptomic RWE proteins, and our work revealed potential crosstalks between m6A and other epitranscriptomic modifications. Our modified LC-PRM method with the use of SIL peptides should be applicable for high-throughput profiling of epitranscriptomic RWE proteins in other cell types and in tissues.

The Obesity-associated Fto gene regulates activity of the dopaminergic midbrain circuitry [FTO KO]

Project description:Here we use MeRIP-Seq to analyze global adenosine methylation (m6A) in mRNAs in the midbrain and striatum of Fto-deficient mice. We find that Fto deficiency leads to increased methylation within a subset of mRNAs important for neuronal signaling, including many within the dopaminergic signaling pathway. Collectively, our results show that Fto regulates demethylation of specific mRNAs in vivo, and this activity relates to control of dopaminergic transmission.

RNA-seq of K562 cells treated with the FTO inhibitor CS2 compared to DMSO treated cells

Project description:Increased FTO expression has been connected to resistance to tyrosine kinase inhibitors in CML. To explore the therapeutic potential of targeting FTO in CML, we tested the FTO catalytic inhibitor in the K562 CML cell line. The RNA-seq was performed to identify relevant regulated genes.

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.
