Summary
RNA editing is crucial for Ebola virus glycoprotein (GP) gene transcription. This study confirms RNA editing as a general ebolavirus trait, with varying editing degrees across species.
Area of Science:
- Virology
- Molecular Biology
- Genetics
Background:
- RNA editing is essential for Ebola virus glycoprotein (GP) gene transcription.
- This mechanism was not previously identified in Marburg virus.
Purpose of the Study:
- To investigate RNA editing as a general trait in ebolaviruses.
- To quantify RNA transcripts generated by RNA editing across different ebolavirus species.
- To confirm the expression of GP gene-derived products.
Main Methods:
- Development of a rapid transcript quantification assay (RTQA) for RNA editing analysis.
- Utilized immunoblotting with a pan-ebolavirus monoclonal antibody.
- Tested infections with representative members of 5 ebolavirus species.
Main Results:
- RTQA successfully quantified GP gene transcripts in all tested ebolavirus species.
- Immunoblotting confirmed the expression of both soluble GP and transmembrane GP.
- RNA editing was confirmed as a general characteristic of ebolaviruses.
Conclusions:
- RNA editing is a conserved mechanism across ebolaviruses.
- The extent of RNA editing varies significantly among ebolavirus species.
- Reston virus exhibits the lowest degree of editing, while Bundibugyo virus shows the highest.

9.1K
RNA editing is a post-transcriptional modification where a precursor mRNA (pre-mRNA) nucleotide sequence is changed by base insertion, deletion, or modification. The extent of RNA editing varies from a few hundred bases, in mitochondrial DNA of trypanosomes, to a just single base, in nuclear genes of mammals. Even a single base change in the pre-mRNA can convert a codon for one amino acid into the codon for another amino acid or a stop codon. This type of re-coding can significantly affect the...

00:36Viral Mutations
32.5K
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Viral genomes exhibit remarkable diversity in size, structure, and composition, influencing their replication strategies and interactions with host cells. These genomes consist of either DNA or RNA and may be linear or circular. Additionally, they can be single-stranded or double-stranded, with each configuration affecting how the virus propagates within a host. RNA viruses, for instance, generally have smaller genomes than DNA viruses, a factor that contributes to their high mutation rates and...
