CFL1-induced super enhancer RNA m6A modification promotes local chromatin accessibility and oncogenes transcription in pancreatic cancer [ATAC-seq]

ABSTRACT: Herein, we describe the landscape of m6A on super enhancer RNAs (seRNAs) in pancreatic ductal adenocarcinoma (PDAC) and demonstrate a regulatory axis involving m6A-seRNAs, H3K4me3 modification, chromatin accessibility and oncogenic transcription. our study has revealed the CFL1-YTHDC2-MLL1 epigenetic regulatory axis plays critical roles of dynamic m6A deposition in seRNAs and local chromatin state, which may be a novel oncogenic mechanism in PDAC and shed light on the crosstalk between epitranscriptome and epigenome.

m6A-RIP-seq of Ascl1-induced neurons.

Project description:We performed m6A-RIPs in Ascl1-induced neurons (iNeurons) to investigate the neuronal m6A epitranscriptome. Immunoprecipitation was done twice using two different antibodies, acquired from Abcam and Synaptic Systems (SySy), allowing for a more robust detection of m6A modification marks. Additionally, RIP-seq was performed separately with intact and fragmented RNA. The former approach allowed to identify proportions of m6A-modified transcripts among the total number, while the latter approach provided the information to identify genomic coordinates of m6A peaks.

YTHDC2 regulates spermatogenesis through promoting the translation of N6-methyladenosine-modified RNA

Project description:N6-methyladenosine (m6A) is the most common internal modification in eukaryotic mRNA. It is dynamically installed and removed, and acts as an essential layer of mRNA metabolism, regulating biological processes including stem cell pluripotency, cell differentiation, and energy homeostasis. m6A is recognized by selective binding proteins; YTHDF1 and YTHDF3 work in concert to promote the translation of m6A-containing mRNAs, YTHDF2 expedites mRNA decay, and YTHDC1 affects the splicing of its targets. The biological function of YTHDC2, the final member of the YTH protein family, remains unknown. We report that YTHDC2 selectively binds m6A along its consensus motif GGACU. YTHDC2 promotes translation of its targets, and associates with cellular fractions involved in translation initiation. Ythdc2 knockout mice are infertile and have significantly smaller testes compared to those of littermates. In the testes, Ythdc2 is temporally expressed as meiosis begins, and germ cells of Ythdc2 knockout mice do not develop past the spermatogonium stage. Thus, YTHDC2 is an m6A binding protein that plays essential roles in spermatogenesis.

The RNA m6A reader YTHDC2 recruits TET1 to demethylate transposable elements DNA and prevent neural fate of human pluripotent stem cells [ChIP-seq_2]

Project description:Covalent modifications of RNA and DNA both regulate numerous biological processes, including development and cancer. The most abundant modification of RNA is that of N6-methyladenosine(m6A), while in the case of DNA, the CpG cytosine methylation characterizes cis-regulatory elements for spatial-temporal gene regulation. Recent studies establish a role for RNA m6A in regulating chromatin through histone modifications. However, whether there is also interplay between RNA and DNA methylation remains unknown. We address this question by studying regulation of the primate-specific transposable element (TE), LTR7/HERV-H, that is specifically activated in human embryonic stem cells (hESCs). Exploiting a novel proteomic approach, we find the RNA m6A-reader, YTHDC2, binds to LTR/HERV-H chromatin through interaction with m6A-modified HERV-H transcripts. Significantly, YTHDC2 recruits DNA demethylase, TET1, to activate LTR7/HERV-H via 5-hydroxymethycytosine(5hmC)-mediated DNA methylation. Furthermore, the YTHDC2/LTR7-axis prevents neural conversion of hESCs. Our results establish previously unknown crosstalk between RNA m6A and DNA methylation and new mechanisms controlling TE activity and hESC fate. We focused on the regulation of the primate-specific TE family, LTR7/HERV-H that is specifically active in the pluripotent human embryonic stem cells (hESCs) then silenced in differentiated lineages. We develop CARGO-BioID, a CRISPR-based TE-centric proteomics approach, to identify the proteins associated with thousands of copies of endogenous LTR7/HERV-H loci and potentially regulate their activity in hESCs. We found YTHDC2 and TET1 interact with each other and subsequently regulate m6A level on HERVH transcripts and 5hmC level on HERV-H genomic loci, which is critical for LTR7/HERV-H activities.
