Persistence and clearance of viral RNA in 2019 novel coronavirus disease rehabilitation patients
Chinese Medical Journal, 2020 Background: A patient's infectivity is determined by the presence of the virus in different body fluids, secretions, and excreta. The persistence and clearance of viral RNA from different specimens of patients with 2019 novel coronavirus disease (COVID ...

Viruses, 2012 Hepatitis C virus (HCV) genome multiplication requires the concerted action of the viral RNA, host factors and viral proteins. Recent studies have provided information about the requirement of specific viral RNA motifs that play an active role in the ...

Virus-derived DNA drives mosquito vector tolerance to arboviral infection
Nature Communications, 2016 Mosquitoes tolerate long-lasting viral infections, which makes them efficient vectors for human viral diseases. Here, the authors show that the tolerance of Aedesmosquitoes to infection with dengue or chikungunya viruses depends on the production of ...

Virus Evolution, 2019 Many emerging arboviruses are not transmitted by traditional mosquito vectors, but by lesser-studied arthropods such as ticks, midges, and sand flies. Small RNA (sRNA) silencing pathways are the main antiviral defence mechanism for arthropods, which lack

The effect of RNA stiffness on the self-assembly of virus particles [PDF]
, 2017 Under many in vitro conditions, some small viruses spontaneously encapsidate a single stranded (ss) RNA into a protein shell called the capsid. While viral RNAs are found to be compact and highly branched because of long distance base-pairing between ...

Seasonal dynamics of DNA and RNA viral bioaerosol communities in a daycare center
Microbiome, 2019 Viruses play an important role in ecosystems, including the built environment (BE). While numerous studies have characterized bacterial and fungal microbiomes in the BE, few have focused on the viral microbiome (virome).

Occurrence and seasonal dynamics of RNA viral genotypes in three contrasting temperate lakes
PLoS ONE, 2018 Decades of research have demonstrated the crucial importance of viruses in freshwater ecosystems. However, few studies have focused on the seasonal dynamics and potential hosts of RNA viruses. We surveyed microbial-sized (i.e.

Completion of RNA synthesis by viral RNA replicases [PDF]
Nucleic Acids Research, 2001 How the 5'-terminus of the template affects RNA synthesis by viral RNA replicases is poorly understood. Using short DNA, RNA and RNA-DNA chimeric templates that can direct synthesis of replicase products, we found that DNA templates tend to direct the synthesis of RNA products that are shorter by 1 nt in comparison to RNA templates. Template-length RNA

Two herpesviral noncoding PAN RNAs are functionally homologous but do not associate with common chromatin loci. [PDF]
PLoS Pathogens, 2018 During lytic replication of Kaposi's sarcoma-associated herpesvirus (KSHV), a nuclear viral long noncoding RNA known as PAN RNA becomes the most abundant polyadenylated transcript in the cell. Knockout or knockdown of KSHV PAN RNA results in loss of late
