Depletion of m6A reader protein YTHDC1 induces dilated cardiomyopathy by abnormal splicing of Titin

Project description:N6-methyladenosine (m6A) is the most common internal modification in eukaryotic messenger RNAs (mRNAs) and plays essential roles in mammals. The function of this chemical modification is deciphered by m6A-specific binding proteins of the YTH family. Recent studies indicated that m6A methyltransferase METTL3 ('writer') and demethylase FTO ('eraser') play critical roles in cardiovascular diseases. However, function of m6A 'reader' proteins in the heart is still largely unknown. Here, we report that cardiac-speciﬁc ablation of Ythdc1 in postnatal heart exhibits progressive dilated cardiomyopathy, heart failure and dramatically increases the incidence of postnatal lethality. Mechanically, the transcript of Titin-the major DCM and heart failure related gene-is decorated by m6A modification and directly recognized by YTHDC1, deficiency of Ythdc1 in heart results in abnormal splicing of TTN and disarray of sarcomeric structures in the cardiomyocytes subsequently. Collectively, we demonstrated that YTHDC1-dependent TTN splicing is crucial for the postnatal heart development and cardiac function, which probably provides a potential target for treating DCM through tuning m6A modification of TTN mRNA.

The RNA m6A reader YTHDC1 silences retrotransposons and guards ES cell identity

Project description:The RNA modification N6-methyladenosine (m6A) has critical roles in many biological processes. However, the function of m6A in the early phase of mammalian development remains poorly understood. Here we show that the m6A reader YT521-B homology-domain-containing protein 1 (YTHDC1) is required for the maintenance of mouse embryonic stem (ES) cells in an m6A-dependent manner, and that its deletion initiates cellular reprogramming to a 2C-like state. Mechanistically, YTHDC1 binds to the transcripts of retrotransposons (such as intracisternal A particles, ERVK and LINE1) in mouse ES cells and its depletion results in the reactivation of these silenced retrotransposons, accompanied by a global decrease in SETDB1-mediated trimethylation at lysine 9 of histone H3 (H3K9me3). We further demonstrate that YTHDC1 and its target m6A RNAs act upstream of SETDB1 to repress retrotransposons and Dux, the master inducer of the two-cell stage (2C)-like program. This study reveals an essential role for m6A RNA and YTHDC1 in chromatin modification and retrotransposon repression. This SuperSeries is composed of the SubSeries listed below.

YTHDC1 m6A-dependent and m6A-independent functions converge to preserve DNA damage response (Ythdc1 ChIP-Seq)

Project description:Cells have evolved a robust and highly regulated DNA damage response to preserve their genomic integrity. Although increasing evidence highlights the relevance of RNA regulation, our understanding of its impact on a fully efficient DNA damage response remains limited. Here, through a targeted CRISPR-knockout screen, we identified RNA binding proteins and modifiers that participate in mediating the p53 response. Among the top hits, m6A reader YTHDC1 was identified as a master regulator of p53 expression. YTHDC1 binds to the transcription start sites ofTP53and other genes involved in DNA damage response, promoting their transcriptional elongation. YTHDC1 deficiency leads to reducedTP53expression, and also retention of introns leading to aberrant protein production of key DNA damage factors. While intron retention is dependent on m6A, YTHDC1 favoursTP53transcriptionalpause-release independently of m6A. Depletion of YTHDC1 causes genomic instability and aberrant cancer cell proliferation mediated by genes regulated by YTHDC1. Our results uncover YTHDC1 as an orchestrator of the DNA damage response through distinct mechanisms of co-transcriptional mRNA regulation.

RNA N6-methyladenosine reader YTHDC1 is essential for TGF-beta-mediated metastasis of triple negative breast cancer [m6A-Seq]

Project description:RNA N6-methyladenosine (m6A) modification and its regulators fine tune gene expression and contribute to tumorigenesis. Here, we uncover the oncogenic role and mechanism of YTHDC1, an m6A reader positively correlated to poor prognosis in breast cancer patients. In a mammary fat pad mouse model, YTHDC1 significantly promoted lung metastasis of triple negative breast cancer (TNBC) cells. Using transcriptome-wide sequencing techniques, we found dysregulation of metastasis-related pathways following YTHDC1 depletion and demonstrated that YTHDC1 is critical for nuclear export of SMAD3 mRNA. YTHDC1 depletion desensitizes TNBC cells to TGF-β, resulting in impaired TGF-β-induced gene signature and inhibition on epithelial-mesenchymal transition (EMT) and cell migration/invasion, which could be at least partially restored by SMAD3 overexpression. Furthermore, we show that the ability of YTHDC1 to recognize m6A on SMAD3 RNA is important for its oncogenic role. Collectively, our study unravels YTHDC1 as vital for distant TNBC metastasis by promoting TGF-β-mediated EMT via SMAD3.
