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

Structural basis of YTH domain as m6A reader

Project description:The N6-methyladenosine (m6A) is the most abundant internal modification in almost all eukaryotic messenger RNAs, and is dynamically regulated. Therefore, identification of m6A readers is especially important in determining the cellular function of m6A. YTHDF2 has recently been characterized as the first m6A reader that regulates the cytoplasmic stability of methylated RNA. Here we show that YTHDC1 is a nuclear m6A reader and report the crystal structure of the YTH domain of YTHDC1 bound to m6A-containing RNA. We further determined the structure of another YTH domain, YTHDF1, and found that the YTH domain utilizes a conserved aromatic cage to specifically recognize the methyl group of m6A. Our structural characterizations of the YTHDC1-m6A RNA complex also shed light on the molecular basis for the preferential binding of the GG(m6A)C sequence by YTHDC1 and confirm the YTH domain as a specific m6A RNA reader. PAR-CLIP (Photoactivatable-Ribonucleoside-Enhanced Crosslinking and Immunoprecipitation) was applied to human YTHDC1 protein to identify its binding sites.

MS-based characterization of YTHDC1 interactome

Project description:Heat shock induces a cell response leading to profound changes in genome expression. Recently, N6-methyladenosine (m6A) RNA modification has been implicated in this response, but with limited information of its role in the heat-induced reprograming of gene expression. Most of m6A molecular and cellular functions rely on m6A readers and the best characterized m6A readers are members of the YTH-domain-containing protein family present from yeast to humans. To investigate the function of the nuclear m6A reader YTHDC1, we characterized its binding partners.

N6-methyladenosine Modulates Messenger RNA Translation Efficiency

Project description:N6-methyladenosine (m6A) is the most abundant internal messenger (mRNA) modification in mammalian mRNA. This modification is reversible and non-stoichiometric, which potentially adds an additional layer of variety and dynamic control of mRNA metabolism. The m6A-modified mRNA can be selectively recognized by the YTH family “reader” proteins. The preferential binding of m6A-containing mRNA by YTHDF2 is known to reduce the stability of the target transcripts; however, the exact effects of m6A on translation has yet to be elucidated. Here we show that another m6A reader protein, YTHDF1, promotes ribosome loading of its target transcripts. YTHDF1 forms a complex with translation initiation factors to elevate the translation efficiency of its bound mRNA. In a unified mechanism of translation control through m6A, the YTHDF2-mediated decay controls the lifetime of target transcripts; whereas, the YTHDF1-based translation promotion increases the translation efficiency to ensure effective protein production from relatively short-lived transcripts that are marked by m6A. PAR-CLIP and RIP was used to identify YTHDF1 binding sites followed by ribosome profling and RNA seq to assess the consequences of YTHDF1 siRNA knock-down

Nuclear m6 A reader YTHDC1 suppresses proximal alternative polyadenylation sites by interfering with the 3' processing machinery

Project description:N6-methyladenosine (m6 A) and alternative polyadenylation (APA) are important regulators of gene expression in eukaryotes. Recently, it was found that m6 A is closely related to APA. However, the molecular mechanism of this new APA regulation remains elusive. Here, we show that YTHDC1, a nuclear m6 A reader, can suppress proximal APA sites and produce longer 3' UTR transcripts by binding to their upstream m6 A sites. YTHDC1 can directly interact with the 3' end processing factor FIP1L1 and interfere with its ability to recruit CPSF4. Binding to the m6 A sites can promote liquid-liquid phase separation of YTHDC1 and FIP1L1, which may play an important role in their interaction and APA regulation. Collectively, YTHDC1 as an m6 A "reader" links m6 A modification with pre-mRNA 3' end processing, providing a new mechanism for APA regulation.
