MeRIP, RIP and RNA Sequencing of the H1299 stable cell lines which the endogenous YTHDF2 was silenced by a short hairpin RNA targeting YTHDF2 3’UTR (shYTHDF2) and then re-expressed Flag-tagged YTHDF2-WT orYTHDF2-K571R

ABSTRACT: 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.

YTHDF2 iCLIP in glioblastoma stem cells

Project description:Glioblastoma is a universally lethal cancer driven by glioblastoma stem cells (GSCs). Here, we interrogated N6-methyladenosine (m6A) mRNA modifications in GSCs by methyl RNA-immunoprecipitation followed by sequencing (meRIP-seq) and transcriptome analysis, finding transcripts marked by m6A often upregulated. Interrogating m6A regulators, GSCs displayed preferential expression as well as in vitro and in vivo dependency of the m6A reader, YTHDF2, in contrast to normal neural stem cells (NSCs). While YTHDF2 has been reported to destabilize mRNAs, YTHDF2 stabilized the oncogene transcripts, MYC and VEGFA, in GSCs in an m6A-dependent manner. We identified IGFBP3 as a downstream effector of the YTHDF2-MYC axis in GSCs and IGF1/IGF1R inhibitor, Linsitinib, as preferentially targeting YTHDF2-expressing cells, inhibiting the viability of GSCs without affecting NSCs and impairing in vivo glioblastoma growth. Thus, YTHDF2 links RNA epitranscriptomic modifications and GSC growth, laying the foundation for the YTHDF2-MYC-IGFBP3 axis as a specific and novel therapeutic target in glioblastoma.

m6A meRIP-Seq from Ythdf2CTL pre-leukemic cells

Project description:The mRNA m6A reader YTHDF2 is overexpressed in a broad spectrum of human acute myeloid leukemias (AML). To understand the role of YTHDF2 in AML, we generated m6A meRIP-seq libraries form Ythdf2fl/fl (Ythdf2CTL) pre-leukemic cells.

Anti YTHDF2 RIP-seq to identify YTHDF2 target mRNAs in P0 mouse retinas

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.

Effect of Ythdf2 in haematopoiesis [meRIP-seq]

Project description:The mRNA m6A reader YTHDF2 is overexpressed in human acute myeloid leukaemias. To understand the role of YTHDF2 in normal haematopoiesis and ageing, we performed SMART-seq on haematopoietic stem cells (HSCs) derived from young and aged (1 year old) mice. In parallel, to identify transcripts likely methylated in HSCs we performed meRIP-seq analysis of c-Kit+ cells.

YTHDF2 mediates the mRNA degradation in prostate cancer in m6A-dependent way

Project description:As the crucial m6A reader, YTHDF2 usually degrades the target mRNAs by recognizing the m6A modified sites, consequently altering m6A levels of each mRNA. In this study, we used m6A MeRIP sequencing to detect the m6A modification alterations in prostate cancer (PCa) cell line after knocking down YTHDF2 and identify how YTHDF2 promote the PCa progression by mediating the mRNA degradation in m6A-dependent way.

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.
