Methyltransferase-like 3 Modulates Severe Acute Respiratory Syndrome Coronavirus-2 RNA N6-Methyladenosine Modification and Replication

mBio, 2021
The coronavirus disease 2019 pandemic caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is an ongoing global public crisis. Although viral RNA modification has been reported based on the transcriptome architecture, the types and ...

Discontinuous template switching generates coronavirus subgenomic RNAs from the 3ʹ viral genome end by 5ʹ to 3ʹ transcription

Journal of Virology
In coronavirus (CoV)-infected cells, several structural and accessory proteins are synthesized from subgenome RNAs (sgRNA) containing a common genomic 5ʹ-leader followed by a given open reading frame (ORF).

RNA Structures and Their Role in Selective Genome Packaging

Viruses, 2021
To generate infectious viral particles, viruses must specifically select their genomic RNA from milieu that contains a complex mixture of cellular or non-genomic viral RNAs.

Viral RNA export

Chemistry & Biology, 1997
Viruses can express intron-containing and intronless mRNAs, which are exported by alternative pathways. The study of the nuclear export of these unconventional mRNAs can provide key insights into the normal process of nuclear export and the alternative pathways provide an attractive target for the development of specific antiviral therapies.

Viral RNA load in plasma is associated with critical illness and a dysregulated host response in COVID-19

Critical Care, 2020
Background COVID-19 can course with respiratory and extrapulmonary disease. SARS-CoV-2 RNA is detected in respiratory samples but also in blood, stool and urine. Severe COVID-19 is characterized by a dysregulated host response to this virus.

RNA-based viral vectors

Expert Review of Vaccines, 2014
The advent of reverse genetic approaches to manipulate the genomes of both positive (+) and negative (-) sense RNA viruses allowed researchers to harness these genomes for basic research. Manipulation of positive sense RNA virus genomes occurred first largely because infectious RNA could be transcribed directly from cDNA versions of the RNA genomes ...

Protein expression redirects vesicular stomatitis virus RNA synthesis to cytoplasmic inclusions. [PDF]

PLoS Pathogens, 2010
Positive-strand and double-strand RNA viruses typically compartmentalize their replication machinery in infected cells. This is thought to shield viral RNA from detection by innate immune sensors and favor RNA synthesis. The picture for the non-segmented

Enhanced inflammation and suppressed adaptive immunity in COVID-19 with prolonged RNA shedding

Cell Discovery, 2022
Little is known regarding why a subset of COVID-19 patients exhibited prolonged positivity of SARS-CoV-2 infection. Here, we found that patients with long viral RNA course (LC) exhibited prolonged high-level IgG antibodies and higher regulatory T (Treg ...

Reovirus Nonstructural Protein σNS Recruits Viral RNA to Replication Organelles

mBio, 2021
The function of the mammalian orthoreovirus (reovirus) σNS nonstructural protein is enigmatic. σNS is an RNA-binding protein that forms oligomers and enhances the stability of bound RNAs, but the mechanisms by which it contributes to reovirus replication
