YTHDF2-m6A-NF-kB axis controls anti-tumor immunity through regulating intratumoral Treg survival and function [RIP-seq]

Project description:N6-methyladenosine (m6A) in messenger RNA (mRNA) regulates immune cells in homeostasis and in response to infection and inflammation. The function of YTHDF2 in the tumor microenvironment (TME) in these contexts has not been explored. We discovered that loss of Ythdf2 in regulatory T (Treg) cells can reduce tumor growth in mice while maintaining peripheral homeostasis. In the tumor microenvironment, Ythdf2-deficient Treg cells have impaired function and poor survival. The elevated tumor necrosis factor (TNF) signaling in the TME grants the location-specific function of YTHDF2, which participates in the feedback regulation of NF-kB signaling by accelerating the degradation of m6A-modified, NF-kB negative regulators, Nlrc3, Nfkbie, and Traf3. TME-specific regulation of Treg by YTHDF2 points to YTHDF2 as a target for anti-cancer immunotherapy, where intratumoral Treg cells can be targeted to enhance antitumor immune response, while avoiding Treg cells in the periphery to minimize undesired inflammations.

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.

YTHDF2/m6A/NF-κB axis controls anti-tumor immunity by regulating intratumoral Tregs

Project description:N6-methyladenosine (m6A) in messenger RNA (mRNA) regulates immune cells in homeostasis and in response to infection and inflammation. The function of the m6A reader YTHDF2 in the tumor microenvironment (TME) in these contexts has not been explored. We discovered that the loss of YTHDF2 in regulatory T (Treg) cells reduces tumor growth in mice. Deletion of Ythdf2 in Tregs does not affect peripheral immune homeostasis but leads to increased apoptosis and impaired suppressive function of Treg cells in the TME. Elevated tumor necrosis factor (TNF) signaling in the TME promotes YTHDF2 expression, which in turn regulates NF-κB signaling by accelerating the degradation of m6 A-modified transcripts that encode NF-κB-negative regulators. This TME-specific regulation of Treg by YTHDF2 points to YTHDF2 as a potential target for anti-cancer immunotherapy, where intratumoral Treg cells can be targeted to enhance anti-tumor immune response while avoiding Treg cells in the periphery to minimize undesired inflammations.

Anti-YTHDF2 RIP-Seq to identify YTHDF2 target mRNAs in hippocampus

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.

Anti-YTHDF1 and anti-YTHDF2 RIP-Seq to identify the target mRNAs for YTHDF1 and YTHDF2, respectively

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.

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

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.
