Transcriptome-wide N6-methyladenosine modification profiling of mRNAs during infection of Newcastle disease virus in Chicken Macrophages

ABSTRACT: N6-methyladenosine (m6A) modification is the most prevalent post-transcriptional modification of mRNA in eukaryotes and has been reported to play an important role in viral infection. However, the role of m6A modification during Newcastle disease virus infection (NDV) is not clear. In this study, we profiled the transcriptome-wide m6A modification of mRNA in NDV-infected chicken macrophages using MeRIP-seq. we identified a total of 9496 significantly changed peaks, of which 7015 peaks distributed across 3320 genes were significantly up-regulated and 2481 peaks distributed across 1264 genes were significantly down-regulated. Combined analysis of m6A peaks and mRNA expression revealed 1234 mRNAs with significantly altered methylation and expression levels after NDV infection, and m6A modification tended to have a negatively correlation with mRNA expression, suggesting that m6A modification may regulate the process of NDV infection by regulating gene expression, especially innate immunity-related genes. To our knowledge, This is the first comprehensive characterization of m6A patterns of the mRNA in chicken macrophages after NDV infection, and provides a valuable basis for further exploring the role of m6A modification in the process of NDV infection.

m6A sequencing analysis of chicken hepatic mRNA under normal and LPS stimulated conditions

Project description:Here, the m6A modification patterns in chicken liver at the acute stage of LPS-stimulated inflammation and at the normal state were explored via m6A and RNA sequencing and bioinformatics analysis. A total of 7815 m6A peaks distributed in 5066 genes were identified in the normal chicken liver, and were mostly located in the CDS, 3’UTR region and around the stop codon. At 2 h after the LPS intraperitoneal injection, the m6A modification pattern changed, and showed 1200 different m6A peaks. The hyper- and hypo-m6A peaks were differentially located, with the former mostly located in the CDS region and the later in the 3’UTR and in the region near the stop codon. The hyper- or hypo methylated genes were enriched in different GO ontrology and pathways. Co-analysis revealed a significantly positive relationship between the fold change of m6A methylation level and the relative fold change of mRNA expression. Moreover, protein and protein interaction analysis showed that genes with altered m6A methylation and mRNA expression levels were clustered in processes involved in lipid metabolism, immune response, DNA replication and protein ubiquitination. CD18 and SREBP-1 were the two hub genes clustered in the immune process and lipid metabolism, respectively. Hub gene AGPAT2 was suggested to link the immune response and lipid metabolism clusters in the PPI network. This study presented the first m6A map of broiler chicken liver at the acute stage of LPS induced inflammation. The findings may shed lights on the possible mechanisms of m6A-mediated lipid metabolism disorder in inflammation.

Transcriptome-wide N6-methyladenosine modification profiling of long non-coding RNAs and circular RNA during growth of Marek’s disease virus in vitro

Project description:we profiled the transcriptome-wide m6A modification in lncRNAs and circRNA in MDV-infected chicken embryo fibroblast (CEF) cells. Methylated RNA immunoprecipitation sequencing results revealed that the lncRNA m6A modification is highly conserved with MDV infection increasing the expression of lncRNA m6A modified sites compared to uninfected cell controls. m6A modification was highly conserved in circRNAs. Comparing to the uninfected group, the number of peaks, conserved motifs, and abundance of circRNA m6A modification, was not significantly different in cells that were infected with MDV. Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes pathway (KEGG) analysis revealed that lncRNA m6A modifications were highly associated with signaling pathways associated with MDV infection. The alterations seen in transcriptome-wide m6A occurring in lncRNAs following MDV-infection suggest this process plays important regulatory roles during MDV replication. And the insulin signaling pathway was associated with the regulation of m6A modified circRNAs in MDV infection. In summary, we report for the first time profiling of the alterations in transcriptome-wide m6A modification in lncRNAs and circRNA of MDV-infected CEF cells.

Widespread Occurrence of m6A in bacterial mRNA

Project description:N6-methyladenosine (m6A) is one of the most abundant modifications in eukaryotic RNA. Recent mapping of m6A methylomes in mammals, yeast, and plants as well as characterization of m6A methyltransferases, demethylases, and binding proteins have revealed regulatory functions of this dynamic RNA modification. In bacteria, although m6A is present in ribosomal RNA (rRNA), its occurrence in messenger RNA (mRNA) still remains elusive. Here, we used liquid chromatography-mass spectrometry (LC-MS) to calculate the m6A/A ratio in mRNA from a wide range of bacterial species, which demonstrates that m6A is an abundant mRNA modification in tested bacteria. Subsequent transcriptome-wide m6A profiling in Escherichia coli and Pseudomonas aeruginosa revealed a conserved distinct m6A pattern that is significantly different from that in eukaryotes. Most m6A peaks are located inside open reading frames (ORF), and carry a unique consensus motif (GCCAU). Functional enrichment analysis of bacterial m6A peaks indicates that the majority of m6A-modified transcripts are associated with respiration, amino acids metabolism, stress response, and small RNAs genes, suggesting potential regulatory roles of m6A in these pathways. m6A profiling in E.coli and P.aeruginosa mRNA

RNA-Seq Analysis of Spleen from Chicken and Japanese Quail infected with Lentogenic and Velogenic Newcastle Disease Virus

Project description:Newcastle disease (ND) affects a few hundred avian species including chicken, and the clinical outcome of Newcastle disease virus (NDV) infection ranges from mild to severe fatal disease depending on the NDV pathotype and the host species involved. Japanese quails serve as natural reservoirs of NDV and play important role in NDV epidemiology. While infection of chicken with velogenic NDV results in severe often fatal illness, the same infection in Japanese quails is results in in apparent infection. The molecular basis of this contrasting clinical outcomes of NDV infection is not yet known. We compared global gene expression in spleens of chicken and Japanese quails infected with a lentogenic or velogenic NDVs. We found contrasting regulation of key genes associated with NF-κB pathway and T-cell activation between chicken and Japanese quails. Our data suggests association of NDV resistance in Japanese quails to activation of NF-κB pathway and T cell proliferation.

Analysis of m6A methylome in CHAPIR overexpressed heart [MeRIP]

Project description:To elucidate the molecular mechanism by which cardiac-hypertrophy-associated piRNA (CHAPIR) regulates m6A modification, we performed m6A methylated RNA immunoprecipitation sequencing (MeRIP-seq) in control or CHAPIR-overexpressing mice heart. The sequential analysis of m6A peaks showed that RGACH motif was highly enriched within m6A sites in heart and that is aligning with the classical consensus sequence of mammals ‘RGACH’, where ‘R’ indicates purine (A/G) and ‘H’ indicates non-guanine base (A/C/U). In CHAPIR treated heart, m6A mostly occurred in mRNAs (89.5%) and only about 10.5% were identified in non-coding RNAs. The majority of mRNAs contain one or two m6A peaks (89.2%) and 10.8% mRNA contain >2 m6A peaks . M6A peaks were predominantly distributed in coding sequences (CDSs), 3’ untranslated regions (3’UTRs) and near stop codon.

Comprehensive analysis of the transcriptome-wide m6A methylome in pterygium by MeRIP sequencing

Project description:Aim: Pterygium is a common ocular surface disease, which is affected by a variety of factors. Invasion of the cornea can cause severe vision loss. N6-methyladenosine (m6A) is a common post-transcriptional modification of eukaryotic mRNA, which can regulate mRNA splicing, stability, nuclear transport, and translation. To our best knowledge, there is no current research on the mechanism of m6A in pterygium. Methods: We recruited 24 pterygium patients from Shanghai Yangpu Hospital, and the level of m6A modification was detected using an m6A RNA Methylation Quantification Kit. Expression and location of METTL3, a key m6A methyltransferase, were identified by immunostaining. Then we used m6A-modified RNA immunoprecipitation sequencing (MeRIP-seq), RNA sequencing (RNA-seq) and bioinformatics analyses to compare the differential expression of m6A methylation in pterygium and normal conjunctival tissue. Results: We identified 2949 dysregulated m6A peaks in pterygium tissue, of which 2145 were significantly upregulated and 804 were significantly downregulated. The altered m6A peak of genes were found to play a key role in the Hippo signaling pathway and endocytosis. Joint analyses of MeRIP-seq and RNA-seq data identified 72 hypermethylated m6A peaks and 15 hypomethylated m6A peaks in mRNA. After analyzing the differentially methylated m6A peaks and synchronously differentially expressed genes, we searched the Gene Expression Omnibus database and identified five genes related to the development of pterygium (DSP, MXRA5, ARHGAP35, TMEM43, and OLFML2A). Conclusion: Our research shows that m6A modification plays an important role in the development of pterygium and can be used as a potential new target for the treatment of pterygium in the future.

Transcriptome-wide m6A methylation of Wuhua yellow-feathered chicken ovary revealed potential molecular mechanisms underlying the low egg performance

Project description:RNA N6-melthyladenosine has been suggested to play important roles in various biological processes. Chicken ovary development is a process controlled by complex gene regulations. In this study, transcriptome-wide m6A methylation of the Wuhua yellow-feathered chicken ovaries before and after sexual maturation was profiled to identify potential molecular mechanisms underlying chicken ovary development. The results showed that m6A levels of mRNAs changed dramatically during sexual maturity. A total of 1476 differential m6A peaks were found between these two stages with 662 significantly up-regulated methylation peaks and 814 down-regulated methylation peaks after sexual maturation. A positive correlation was found between the m6A peaks and gene expression levels. Functional enrichment analysis indicated that apoptosis related pathways might be the key molecular regulatory pathway underlying the poor reproductive performance of Wuhua yellow-feathered chicken. The fine expressional regulation of genes related to follicles development and follicle atresia controlled by m6A during the maturity results in the poor reproductive performance in the Wuhua yellow-feathered chicken. However, the regulatory mechanisms are still unclear, thus more further studies are required. The pathways and corresponding candidate genes found here may be useful for molecular design breeding for improving egg production performance in Chinese local chicken breed, and it will also benefit for the genetic resource protection of valuable avian species.
