Targeting FTO suppresses hepatocellular carcinoma by inhibiting ERBB3 and TUBB4A expression [MeRIP]

Project description:Fat mass and obesity-associated protein (FTO) is an N6-methyladenosine (m6A) demethylase and plays a critical oncogenic role in various cancers. Here we show that FTO is an effective target in hepatocellular carcinoma (HCC). FTO is highly expressed in clinical patients of HCC and presents as a poor prognostic factor. Genetic depletion of FTO dramatically attenuated HCC progression in vivo. Pharmacological inhibition of FTO by FB23/FB23-2 remarkably suppressed the proliferation and migration of HCC cell lines in vitro, as well as inhibiting the HCC tumorigenicity in xeno-transplanted mice. Mechanistically, FB23-2 suppressed the expression of Erb-b2 receptor tyrosine kinase 3 (ERBB3) and human tubulin beta class Iva (TUBB4A) by increasing the m6A level in these mRNA transcripts. The decreased ERBB3 resulted in inhibited Akt-mTOR signaling that subsequently impaired the proliferation and survival of HCC cells. Moreover, FB23-2 abolished the organization of the tubulin cytoskeleton, while enforced expression of TUBB4A rescued the migration of HCC cells. Collectively, our study demonstrated that FTO plays a critical role in HCC by maintaining the proliferation and migration of cells, and highlights the broad potential of FTO inhibitors for targeting HCC.

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.

Sequencing results of FTO overexpressing in papillary thyroid cells [meRIP-seq]

Project description:We tried to analyze the effect of FTO on papillary thyroid carcinoma. We constructed a FTO overexpression stable cell line of papillary thyroid carcinoma cells. We performed meRIP-seq sequencing analysis of the FTO overexpression stable transfer cell line to try to assess which genes were changed at the m6A level in papillary thyroid cancer cells by overexpressing FTO.

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.
