The m6A epitranscriptomic landscape of Setaria viridis and the domesticated foxtail millet (S. italica)

ABSTRACT: N6-methyladenosine (m6A) is a pivotal epitranscriptomic modification that regulates mRNA metabolism and plays critical roles in plant growth and environmental responses. However, the evolution and roles of m6A modifications in plant domestication remain largely unexplored. This study combined RNA-seq and MeRIP-seq data to compare m6A modifications profiles between foxtail millet (Setaria italica, Yugu1) and its wild ancestor S. viridis (A10). Peak calling analysis identified 6,928 m6A peaks associated with 6,407 protein-coding genes in Yugu1 and 6,274 m6A peaks in 5,858 genes in A10, respectively. Comparative analysis revealed numerous differentially expressed genes (DEGs) and differentially methylated peaks (DMPs), whose functions were elucidated by GO and KEGG enrichment analyses. Integration of DMPs paired with DEGs, we found 209 hyper-methylated peaks associated with upregulated transcription levels, and 90 hypo-methylated peaks associated with downregulated transcription levels. This dataset provides valuable resource for further investigating the roles of m⁶A modification in crop domestication.

Comprehensive analysis of differentially expressed profiles of mRNA N6-methyladenosine in colorectal cancer

Project description:Purpose: To comprehensively profile the landscape of the mRNA N6-methyladenosine (m6A) modification in human colorectal cancer (CRC). Methylated RNA immunoprecipitation sequencing (MeRIP-seq) was explored to compare the difference in mRNA N6-methyladenosine (m6A) methylation between CRC tissues and adjacent normal control (NC) tissue. RNA-sequencing (RNA-seq) was performed to transcribe differentially expressed mRNAs. Conjoint analysis of MeRIP-seq and RNA-seq data was conducted to predict RNA-binding proteins (RBPs). Results: MeRIP-seq identified 1110 differentially m6A methylated sites (DMMSs) and 980 differentially m6A methylated genes (DMMGs) in CRC, with 50.13% of all modified genes showing unique m6A-modified peaks in CRC. RNA-seq showed 915 upregulated genes and 1463 downregulated genes in CRC. QRT-PCR verified the RNA-seq results by detecting the expression of some mRNAs. Conjoint analysis of MeRIP-seq and RNA-seq identified 400 differentially m6A methylated and expressed genes (DEGs), and pathway analysis detected that DMMGs and DEGs were closely related to cancer. After analyzing these DMMGs and DEGs through the GEPIA database, we found that the expression of B3GNT6, DKC1, SRPK1 and RIMKLB were associated with prognosis, and the expression of B3GNT6 and RIMKLB were associated with clinical stage. 17 RBPs were identified based on the DMMGs and DEGs, among which FXR1, FXR2, FMR1, IGF2BP2, IGF2BP3 and SRSF1 were obviously highly expressed in CRC, and FMR1, IGF2BP2 and IGF2BP3 were closely related to methylation, and might be involved in the development of CRC. Conclusions: This study comprehensively profiled m6A modification of mRNAs in CRC, which revealed possible mechanisms of m6A-mediated gene expression regulation.

Transcriptome-wide analysis of RNA N6-methyladenosine in Adriamycin-resistant acute myeloid leukemia cells

Project description:N6-Methyladenosine (m6A) is the most abundant post-transcriptional modification in eukaryotes, the imbalance of which is reported to be associated with various pathological processes, including drug resistance. In this study, we analyzed the methylated RNA immunoprecipitation combined with next-generation sequencing (MeRIP-seq) data of AML cell line HL60 and its adriamycin-resistant cell line HL60/ADR. We found a total of 40550 peaks, representing 15640 genes in HL60, and a total of 38834 peaks, representing 15285 genes in HL60/ADR. A total of 4437 differentially methylated m6A peaks within 3461 genes have been found between HL60 and HL60/ADR. Among them, 3587 differentially m6A peaks within 2790 genes were hyper-methylated, and 850 m6A peaks within 671 genes were hypo-methylated. KEGG pathway analysis showed that pathways were enriched in tumor and drug-resistant related signaling pathway. Results of MeRIP-seq showed that fold enrichment of global m6A peaks was higher in HL60/ADR compared to HL60. This study provides a framework for the application of comprehensive mRNA m6A profiling towards acute myeloid leukemia cell line (HL60) and its adriamycin-resistant acute myeloid leukemia cell line (HL60/ADR).

Transcriptome-wide m6A profiling reveals mRNA post-transcriptional modification of boar sperm during cryopreservation

Project description:In present study, we first tried to reveal the transcriptome-wide m6A methylation pattern in boar fresh sperm (Fs) and frozen-thawed sperm (Fts) through MeRIP-seq, which demonstrates occurrence the diverse m6A modiﬁcation patterns during cryopreservation. Results: the expression of m6A modification enzymes were significantly dysregulated in sperm during cryopreservation. Furthermore, the m6A peaks were mainly enriched in coding regions and near stop codons with classical RRACH motifs. In Fts, a total of 1754 differentially methylated m6A genes containing 1928 differentially methylated peaks were identified as compared to Fs. Bioinformatics analysis revealed the role of these genes containing significantly altered m6A peaks (DMMGs) were significantly enriched in terms of metabolism and transcription, as well as a number of DMMGs were annotated to ubiquitin mediated proteolysis, AMPK, mTOR and MAPK signaling pathways. Furthermore, the joint analysis of DMMGs and differentially expressed genes indicated that both of these play a vital role in sperm energy metabolism and apoptosis. Conclusion: Our study is first to reveal the dynamic m6A modification in mRNAs of boar sperm during cryopreservation, and provides a new evidence regarding the potential roles of m6A in modulating sperm motility, apoptosis and metabolism.

The m6A RNA modification modulates gene expression and fibrosis-related pathways in hypertrophic scar [m6A-seq]

Project description:Purpose: To systematically analyze the overall m6A modification pattern in hyperplastic scars (HS). Methods: The m6A modification patterns in HS and normal skin (NS) tissues were described by m6A sequencing and RNA sequencing, and subsequently bioinformatics analysis was performed. The m6A-related RNA was immunoprecipitated and verified by real-time quantitative PCR. Results: The appearance of 14,791 new m6A peaks in the HS sample was accompanied by the disappearance of 7,835 peaks. The unique m6A-related genes in HS were thus associated with fibrosis-related pathways. We identified the differentially expressed mRNA transcripts in HS samples with hyper-methylated or hypo-methylated m6A peaks. Conclusion: This study is the first to map the m6A transcriptome of human HS, which may help clarify the possible mechanism of m6A-mediated gene expression regulation.
