M6A Demethylase FTO-mediated downregulation of DACT1 mRNA stability promotes Wnt signaling to facilitate osteosarcoma progression [RNA-seq]

Project description:Despite advances in clinical diagnosis and treatment, the prognosis of patients with osteosarcoma (OS) remains poor, and the treatment efficacy has plateaued. Therefore, it is important to identify new therapeutic targets for OS. N6-methyladenosine (m6A) modification has been reported to participate in tumor malignancy. In this study, functional screening found that the m6A demethylase FTO could be a candidate therapeutic target for OS. Upregulated FTO in OS could predict a poorer prognosis. FTO promoted the growth and metastasis of OS in vitro and in vivo. Methylated RNA immunoprecipitation sequencing (MeRIP-seq) and RNA sequencing (RNA-seq) were performed to identify DACT1 as a potential target of FTO. In vitro assays demonstrated that FTO could reduce the mRNA stability of DACT1 via m6A demethylation, which decreased DACT1 expression and further activated the Wnt signaling pathway. The oncogenic effect of FTO on OS was dependent on DACT1. In addition, the m6A reader IGF2BP1 was validated to participate in the regulation of DACT1. Entacapone, a conventional drug for Parkinson's disease, was confirmed to suppress OS via m6A-mediated regulation through the FTO/DACT1 axis. Our findings demonstrate that FTO may be a novel therapeutic target and that entacapone has the preclinical value to be repurposed for OS.

Adiponectin-cre FTO flox/flox and FTO flox/flox mouse white fat tissues

Project description:Single nucleotide polymorphisms in intron 1 of the fat mass and obesity-associated (FTO) gene were found to be associated with an increased risk of adult obesity. Enhanced FTO expression in mice leads to hyperphagia, increased fat mass, and higher body weight. Neuronal-specific FTOâ??deleted mice have an identical lean body weight phenotype to global FTO-deleted mice. The physiological role of adipose FTO in the homeostasis of energy regulation remains to be elucidated. We used microarrays to elucidate the metabolic pathways that are regulated by FTO in the white fat. FTO flox/flox and Adiponectin-cre FTO flox/flox (AFO) mice were fed with chow diet. White fat tissues from epididymal adipose pad were harvested under ad lib condition for RNA isolation. Three independent pools of FTO flox/flox and AFO mouse white fat RNA were included in the study.

The RNA demethylase FTO controls m6A marking on SARS-CoV-2 and classifies COVID-19 severity in patients

Project description:The RNA modification N6-methyladenosine (m6A) plays a key role in the life cycles of several RNA viruses. Whether this applies to SARS-CoV-2 and whether m6A affects the outcome of COVID-19 disease is still poorly explored. Here we report that the RNA demethylase FTO strongly affects both m6A marking of SARS-CoV-2 and COVID-19 severity. By m6A profiling of SARS-CoV-2, we confirmed in infected cultured cells and showed for the first time in vivo in hamsters that the regions encoding TRS_L and the nucleocapsid protein are multiply marked by m6A, preferentially within RRACH motifs that are specific to β-coronaviruses and well conserved across SARS-CoV-2 variants. In cells, downregulation of the m6A demethylase FTO, occurring upon SARS-CoV-2 infection, increased m6A marking of SARS-CoV-2 RNA and slightly promoted viral replication. In COVID-19 patients, a negative correlation was found between FTO expression and both SARS-CoV-2 expression and disease severity. FTO emerged as a classifier of disease severity and hence a potential stratifier of COVID-19 patients.

High throughput characterization of the m6A demethylase FTO by CLIP and RNAseq

Project description:We performed the CLIP-seq analysis of RNAs bound by 3xFLAG-tagged FTO protein stably expressed in human HEK293 cells. In parallel, we profiled the transcriptome of the same cells by RNA-seq, which was used for CLIPseq bioinformatics analysis as an input. The CRISPR-Cas9 was used to knock-out FTO expression in HEK293 to compare the mRNA expression changes and exon usage between FTO KO and WT cell lines. All experiments were performed in three replicates.

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
