Project description:We investigated the role of O-GlcNAcylation of m6A reader YTHDF2 in HBV-related hepatocarcinogenesis and progression. We found that YTHDF2 O-GlcNAcylation was elevated upon HBV infection through upregulated HBP. OGT-mediated YTHDF2 O-GlcNAcylation at Ser263 enhanced its protein stability, and subsequently changed the gene expression profiles. Mechanistically, we identified YTHDF2 stabilized minichromosome maintenance protein 2 (MCM2) and MCM5 mRNAs in an m6A dependent manner by high-throughput profiling of m6A-seq and RIP-seq, thereby promoting HBV-related HCC tumorigenesis. Importantly, our study proposed that targeting OGT-mediated YTHDF2 O-GlcNAcylation may be a novel strategy for potential treatment of HBV-associated liver cancer.

Project description:To identify the target mRNAs of the m6A reader protein YTHDF2, we carired out anti YTHDF2 RNA Immunoprecipitation (RIP) followed by RNA-sequencencing. Using EZ-Magna RIP™ RNA-Binding Protein Immunoprecipitation Kit (Millipore), RNA from P0 wild type mouse retinas was pulled down by rabbit polyclonal anti-YTHDF2 (proteintech) and then sequenced on Illumina HiSeq3000 platform. The filtered reads were mapped to the mouse reference genome (GRCm38) using STAR v2.5 with default parameters. The resulting bam files were fed to HTSeq tool to count the number of RNA-seq reads, which was further normalized to calculate FPKM. To determine which gene is enriched, we computed the FPKM from RIP elute to input and any fold change greater than 2 was considered enriched. Finally, Biological replicates of anti-YTHDF2 RIP-Seq identified 1639 transcripts. This study provides a gene list which shows mRNA binding with YTHDF2 in mouse retina.

Project description:SUMOylation affects many aspects of target proteins such as activity, stability, localization and protein-protein interactions. We have found that SUMOylation of YTHDF2 increased its binding activity with m6A-RNAs by using different experimental approaches. To confiremd this conclusion,the analysis of RIP-seq, MeRIP-seq and RNA-seq in H1299-shYTHDF2 cells re-expressing YTHDF2-WT and YTHDF2-K571R was performed. MeRIP+RIP targets showed lower binding affinities in the mutant YTHDF2-K571R when compared with YTHDF2-WT. Compared to the control group, the binding capacities of YTHDF2 to RIP targets in treated group with either 2-D08 or GA were decreased, especially to MeRIP+RIP targets. Moreover, SUMOylated YTHDF2 promoted m6A-RNAs degradation. Combined analysis of RNA-seq, RIP-seq and MeRIP-seq showed that the mRNA levels were up-regulated in shYTHDF2 stable cells re-expressing YTHDF2-K571R compared with those in re-expressing YTHDF2-WT.

Project description:To identify the target mRNAs of the m6A reader protein YTHDF2 in mouse hippocampus, we carired out anti YTHDF2 RNA Immunoprecipitation (RIP) followed by RNA-sequencencing. Using EZ-Magna RIP™ RNA-Binding Protein Immunoprecipitation Kit (Millipore), RNA from P40 wild type mouse hippocampus was pulled down by rabbit polyclonal anti-YTHDF2 (proteintech) and then sequenced on Illumina Novaseq 6000. The filtered reads were aligned to the mouse reference genome (GRCm38) using BWA mem (v 0.7.12).Then the MACS2 (version 2.1.0) peak calling software was used to identify regions of IP enrichment over background, followed by the motif detected by Homer (Heinz et al., 2010). Peak related genes are then confirmed by PeakAnnotator. Different peak analysis was based on the fold enrichment of peaks of different experiments. A peak was determined as different peak when the odds ratio between two groups was more than 2. Using the same method, genes associated with different peaks were identified. Finally, Biological replicates of anti-YTHDF2 RIP-Seq identified 408 mRNAs transcripts. This study provides gene lists which shows mRNA binding with YTHDF2 in mouse hippocampus.

Project description:To identify the target mRNAs of the m6A reader protein YTHDF1 and YTHDF2, we carired out anti YTHDF1 and anti YTHDF2 RNA Immunoprecipitation (RIP) followed by RNA-sequencencing. Using EZ-Magna RIP™ RNA-Binding Protein Immunoprecipitation Kit (Millipore), RNA from P6-P8 wild type mouse cerebellum was pulled down by rabbit polyclonal anti-YTHDF1 (proteintech) or polyclonal anti-YTHDF2 (proteintech) and then sequenced on Illumina HiSeq3000 platform. The filtered reads were mapped to the mouse reference genome (GRCm38) using STAR v2.5 with default parameters. The resulting bam files were fed to HTSeq tool to count the number of RNA-seq reads, which was further normalized to calculate FPKM. To determine which gene is enriched, we computed the FPKM from RIP elute to input and any fold change greater than 2 was considered enriched. Finally, Biological replicates of anti-YTHDF1 RIP-Seq and anti-YTHDF2 RIP-Seq identified 506 and 596 mRNAs transcripts, respectively. This study provides gene lists which shows mRNA binding with YTHDF1 and YTHDF2 in mouse cerebellum.

Project description:N6-methyladenosine (m6A) is the most prevalent internal modification present in the mRNA of all higher eukaryotes. Here we present that m6A is selectively recognized by human YTH domain family (YTHDF2) protein to regulate mRNA degradation. By using crosslinking and immunoprecipitation, we have identified over 4000 substrate RNA of YTHDF2 with conserved core motif of G(m6A)C. We further estabilshed the role of YTHDF2 in RNA metabolism by a combination of ribosome profiling, RNA sequencing, m6A level quantification and cell-based imaging: the C-terminal domain of YTHDF2 selectively binds to m6A of mRNA and the N-terminal domain is responsive for localizing mRNA from translatable pool to processing body where mRNA decay occurs. PAR-CLIP and RIP was used to identify YTHDF2 binding sites followed by ribosome profling and RNA seq to assess the consequences of YTHDF2 siRNA knock-down

Project description:To identify the target mRNAs of the m6A reader proteins YTHDF1 and YTHDF2, we carried out anti-YTHDF1 and anti-YTHDF2 RNA Immunoprecipitation (RIP) followed by RNA-sequencing. Using EZ-Magna RIP™ RNA-Binding Protein Immunoprecipitation Kit (Millipore), RNA from E12.5 wild-type mouse cortices and P0 wild-type mouse retinas was pulled down by rabbit polyclonal anti-YTHDF1 (proteintech) and rabbit polyclonal anti-YTHDF2 (proteintech), and then sequenced on Illumina HiSeq3000 platform. The filtered reads were mapped to the mouse reference genome (GRCm38) using STAR v2.5 with default parameters. The resulting bam files were fed to the HTSeq tool to count the number of RNA-seq reads, which was further normalized to calculate FPKM. To determine which gene is enriched, we computed the FPKM from RIP elute to input, and any fold change greater than 2 was considered enriched. From the embryonic cortex, we identified 986 and 1860 mRNAs by anti-YTHDF1 and anti-YTHDF2 RIP-seq, respectively. Anti-YTHDF1 and anti-YTHDF2 RIP-seq in mouse retina identified 2969 and 1638 mRNAs, respectively. This study provides the gene lists which show mRNAs binding with YTHDF1 and YTHDF2 in the mouse cortex and retina.
