Viral RNAs Are Unusually Compact [PDF]

open access: yesPLoS ONE, 2014
A majority of viruses are composed of long single-stranded genomic RNA molecules encapsulated by protein shells with diameters of just a few tens of nanometers. We examine the extent to which these viral RNAs have evolved to be physically compact molecules to facilitate encapsulation. Measurements of equal-length viral, non-viral, coding and non-coding

VGEA: an RNA viral assembly toolkit. [PDF]

open access: yesPeerJ, 2021
Next generation sequencing (NGS)-based studies have vastly increased our understanding of viral diversity. Viral sequence data obtained from NGS experiments are a rich source of information, these data can be used to study their epidemiology, evolution, transmission patterns, and can also inform drug and vaccine design.

A viral deubiquitylating enzyme targets viral RNA-dependent RNA polymerase and affects viral infectivity [PDF]

open access: yesThe EMBO Journal, 2011
Selective protein degradation via the ubiquitin-proteasome system (UPS) plays an essential role in many major cellular processes, including host-pathogen interactions. We previously reported that the tightly regulated viral RNA-dependent RNA polymerase (RdRp) of the positive-strand RNA virus Turnip yellow mosaic virus (TYMV) is degraded by the UPS in ...

RNA Interference for Viral Infections [PDF]

open access: yesCurrent Drug Targets, 2012
The treatment of viral infections has relied on pre-emptive vaccination or use of a limited range of anti-viral drugs. However, the majority of viruses have no available drugs and treatment is merely supportive. RNA interference (RNAi) offers the ability to directly and rapidly treat virus infections via the targeting of viral genes.

Viral suppression of RNA silencing [PDF]

open access: yesScience China Life Sciences, 2012
يلعب إسكات الجينات (إسكات الحمض النووي الريبي) دورًا أساسيًا في الدفاع المضاد للفيروسات في النباتات والفطريات واللافقاريات. تقوم الفيروسات بتشفير البروتينات التي تمنع إسكات الجينات لمواجهة دفاع المضيف. تم تحديد المثبطات الفيروسية لإسكات الحمض النووي الريبي (RSVs) من جميع الفيروسات النباتية تقريبًا التي تولد وبعض فيروسات الحشرات والثدييات. كشفت الدراسات

Viral sensing by RNA helicases

open access: yesVirologie, 2020
A key aspect of antiviral immunity is the distinction between "self" and "non-self" components. This distinction can be established through the detection of double-stranded RNA (dsRNA), a common sign of viral infection, by cytosolic RNA helicases.

Viral noncoding RNAs

open access: yesUirusu, 2009
Many lines of recent evidence indicate that non-coding RNAs including micro RNAs (miRNAs) and small interfering RNAs (siRNAs) play an important role in the control of gene expression in diverse cellular processes and in defense responses against molecular parasites such as viruses and transposons.

Regulation of PKR By Viral RNAS [PDF]

open access: yesBiophysical Journal, 2010
PKR is an interferon-induced kinase that plays a key role in the innate immunity response to viral infection. Upon binding dsRNA, PKR undergoes autophosphorylation reactions that activate the kinase. We have investigated the mechanism of PKR activation by two viral RNAs that regulate PKR. HIV-I TAR is a 23 bp RNA hairpin with three bulges that is known

The Unusual Compactness of Viral RNA [PDF]

open access: yesBiophysical Journal, 2012
We present complementary experimental and computational studies of the relative sizes of equal-length long single-stranded (ss) RNA molecules. Comparison of viral, non-viral, coding and non-coding RNAs of length 2117 nucleotides (nt) shows viral RNA to have among the highest gel-mobilities and smallest hydrodynamic radii in solution.
