M6A IP sequencing analysis of m6A mRNA methylation regulation by arsenic in keratinocytes

ABSTRACT: N6-methyladenosine (m6A) RNA methylation is the most abundant internal chemical modifications in eukaryotic messenger RNA (mRNA) as well as long non-coding RNA (lncRNA). Recently, m6A RNA methylation research was revived by the discovery of the fat mass- and obesity-associated protein (FTO) as the first RNA demethylase, implicating that m6A RNA methylation is a reversible and dynamic modification and may have critical biological functions. Emerging evidence has shown that m6A modifications in mRNAs and lncRNAs play crucial roles in regulating RNA fate and function in biological processes in the past several years. The goal is to determine the targets of arsenic damage including m6A RNA methylation in keratinocytes.

m6A IP sequencing analysis of m6A mRNA methylation regulation by FTO in melanoma cells

Project description:N6-methyladenosine (m6A) RNA methylation is the most abundant internal chemical modifications in eukaryotic messenger RNA (mRNA) as well as long non-coding RNA (lncRNA). Recently, m6A RNA methylation research was revived by the discovery of the fat mass- and obesity-associated protein (FTO) as the first RNA demethylase, implicating that m6A RNA methylation is a reversible and dynamic modification and may have critical biological functions. Emerging evidence has shown that m6A modifications in mRNAs and lncRNAs play crucial roles in regulating RNA fate and function in biological processes in the past several years. As the first identified RNA demethylase that regulates the demethylation of target mRNAs, FTO has been reported to play an oncogenic role in leukemia and glioblastoma stem cells. To identify the target genes of FTO in melanoma cells, we used m6A IP seq coupled with RNA seq to determine the potential demethylation and gene targets across the whole transcriptome for FTO, and identified more than 1,000 genes.

FTO suppresses cardiac fibrosis after myocardial infarction via m6A-mediated epigenetic modification

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.

A lncRNA from the FTO locus acts as an inhibitor of mRNA m6A methylation and p53 tumor suppression

Project description:The FTO gene locus has been linked to cancer and obesity through encoded N6-methyladenosine (m6A) demethylase FTO or inherited genomic variants (e.g. intronic single-nucleotide polymorphisms). Here we demonstrate that FTO-IT1, a long noncoding RNA (lncRNA) transcribed from a FTO gene intron, is upregulated during prostate cancer (PCa) progression and positively correlated with poor survival of patients with tumors only expressing wild-type p53. We show that RBM15, a mRNA/substrate binding subunit of the m6A methyltransferase complex binds and increases mRNA m6A methylation and stability of p53 transcriptional target genes; however, FTO-IT1 overexpression abolishes these effects by blocking RBM15 binding of p53 target gene mRNAs. Therapeutic targeting of FTO-IT1 restores mRNA m6A level and p53 signaling and inhibits PCa tumor growth in mice. Our study identifies FTO-IT1 lncRNA as a bono fide inhibitor of m6A methylation and p53 tumor suppression and nominates FTO-IT1 as a potential biomarker and therapeutic target of cancer.

m6A/m-Seq of mouse adult cortex of Mettl3 cKO or Fto cKO mice

Project description:N6-Methyladenosine (m6A) and N6,2′-O-dimethyladenosine (m6Am) are abundant mRNA modifications that regulate transcript processing and translation. The role of both, here termed m6A/m, in the stress response in the adult brain in vivo are currently unknown. Here, we investigated the effect of gene deletion of Mettl3, a m6A methyltransferase, and Fto, a m6A and m6Am demethlyase, induced in adulthood in excitatory neurons of the neocortex and hippocampus (Camk2a-Cre Mettl3 or Fto cKO) on the cortical epitranscriptome. PolyA-RNA-fragments from 3-5 replicates per group were processed both as m6A/m-sample (RNA immunoprecipiation RIP with an m6A and m6Am antibody) and RNA-input sample.

The interacted proteins of ALKBH5 and FTO identified by IP-mass

Project description:Since m6A demethylases (FTO and ALKBH5) have been reported to be involved in pre-mRNA splicing regulation, we hypothesized that dynamic m6A distribution during mRNA maturation might involve removal of m6A in internal exons by FTO or ALKBH5 accompanied by splicing factors. To explore this we performed pull-down assays coupled with protein mass spectrometry.

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. Profiling of m6A in midbrain and striatum from FTO knockout mice
