AI Article Synopsis

  • The study investigates how the reversible N6-methyladenosine (mA) modification impacts gene expression in long non-coding RNAs (lncRNAs) during Marek's disease virus (MDV) infection in chicken embryonic fibroblast (CEF) cells.
  • The research found that MDV infection increases the expression of mA modified lncRNA sites and these modifications are conserved across different contexts.
  • The results suggest that mA modifications in lncRNAs play significant regulatory roles in the replication of MDV, marking the first comprehensive profiling of these modifications in MDV-infected cells.

Article Abstract

Background: The newly discovered reversible N6-methyladenosine (mA) modification plays an important regulatory role in gene expression. Long non-coding RNAs (lncRNAs) participate in Marek's disease virus (MDV) replication but how mA modifications in lncRNAs are affected during MDV infection is currently unknown. Herein, we profiled the transcriptome-wide mA modification in lncRNAs in MDV-infected chicken embryo fibroblast (CEF) cells.

Results: Methylated RNA immunoprecipitation sequencing results revealed that the lncRNA mA modification is highly conserved with MDV infection increasing the expression of lncRNA mA modified sites compared to uninfected cell controls. Gene Ontology and the Kyoto Encyclopedia of Genes and Genomes pathway analysis revealed that lncRNA mA modifications were highly associated with signaling pathways associated with MDV infection.

Conclusions: In this study, the alterations seen in transcriptome-wide mA occurring in lncRNAs following MDV-infection suggest this process plays important regulatory roles during MDV replication. We report for the first time profiling of the alterations in transcriptome-wide mA modification in lncRNAs of MDV-infected CEF cells.

Since the discovery of RNA in the early 1900s, scientific understanding of RNA form and function has evolved beyond protein coding. Viruses, particularly retroviruses like human T-cell leukemia virus type 1 (HTLV-1), rely heavily on RNA and RNA post-transcriptional modifications to regulate the viral lifecycle, pathogenesis, and evasion of host immune responses. With the emergence of new sequencing technologies in the last decade, our ability to dissect the intricacies of RNA has flourished.

Abnormal base excision repair (BER) pathway and N6-methyladenosine (m6A) of RNA have been proved to be significantly related to age-related cataract (ARC) pathogenesis. However, the relationship between the Nei Endonuclease VIII-Like1 (NEIL1) gene (a representative DNA glycosylase of BER pathway) and its m6A modification remains unclear. Here, we showed that the expression of NEIL1 was decreased in the ARC anterior lens capsules and HO-stimulated SRA01/04 cells.

N6-methyladenosine (m6A) modification of RNA is a critical post-transcriptional modification, that dynamically contributes to testicular development and spermatogenesis. Nevertheless, the investigation into the role of m6A in testicular development of sheep remains insufficient. Herein, we conducted a comprehensive analysis of the m6A transcriptome landscape in the testes of F1 hybrid Southdown × Hu sheep across M0 (0 months old, newborn), M3 (3 months old, sexually immature), M6 (6 months old, sexually mature), and Y1 (1 years old, adult).

METTL3: a multifunctional regulator in diseases.

Mol Cell Biochem

N6-methyladenosine (mA) methylation is the most prevalent and abundant internal modification of mRNAs and is catalyzed by the methyltransferase complex. Methyltransferase-like 3 (METTL3), the best-known mA methyltransferase, has been confirmed to function as a multifunctional regulator in the reversible epitranscriptome modulation of mA modification according to follow-up studies. Accumulating evidence in recent years has shown that METTL3 can regulate a variety of functional genes, that aberrant expression of METTL3 is usually associated with many pathological conditions, and that its expression regulatory mechanism is related mainly to its methyltransferase activity or mRNA posttranslational modification.
