The statistical behaviors of semiflexible polymers confined in nano-and micro-tubes are fundamental problems in polymer physics and have been investigated both experimentally and theoretically for decades [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. The IAV genome consists of eight RNA segments contained in separate viral ribonucleoprotein complexes (vRNPs) that are packaged together into a single virus particle 1,2 . Influenza A viruses (IAVs) are segmented single-stranded negative sense RNA viruses that constitute a major threat to human health.

Inter-segment RNA interactions in the IAV genome. However, it is generally accepted that a strong innate immune dysregulation known as ‘cytokine storm’ contributes to the pathology of infections with the 1918 H1N1 pandemic or the highly pathogenic avian influenza viruses of the H5N1 subtype2,3,4.

As mentioned earlier, mRNA 3′ processing is required for RNAPII transcription termination [1][2][3][4] . Epub 2020 Jun 18. Mol Biol Evol. By directly staining DNA, we observe that DNA catenation between sister chromatids (separated by fluid flow) is composed of distinct fibres of DNA concentrated at the centromeres. 2020 Aug 17;94(17):e00357-20. In addition to demonstrating the value of microfluidics as a tool for examining chromosome structure, these results lend support to certain models of DNA catenation organization and regulation: in particular, we conclude from our observation of centromere-concentrated catenation that spindle forces could play a driving role in decatenation and that Topoisomerase IIα is differentially regulated at the centromeres, perhaps in conjunction with cohesin.

Heterologous Packaging Signals on Segment 4, but Not Segment 6 or Segment 8, Limit Influenza A Virus Reassortment. J Virol. Our study establishes a framework towards further work into IAV RNA structure and vRNP packaging, which will lead to better models for predicting the emergence of new pandemic influenza strains and will facilitate the development of antivirals specifically targeting genome assembly. Combining sample expansion and light sheet microscopy for the volumetric imaging of virus-infected cells with super-resolution. J Virol.

While previous studies have revealed the overall organization of the proteins within vRNPs, characterization of viral RNA structure using conventional structural methods is hampered by limited resolution and an inability to resolve dynamic components12,13. Nucleic acids research 40 (2012) 11428-11434 . Print 2017 Jun 1. We have used a lab-on-a-chip microfluidic device and fluorescence microscopy, coupled with a simple image analysis pipeline, to digest chromosomal proteins and examine the structure of the remaining DNA, which maintains the canonical 'X' shape. The mechanism of initial transcription is unclear due to the presence of transient intermediates and molecular heterogeneity. Termination is a ubiquitous phase in every transcription cycle but is incompletely understood and a subject of debate. All rights reserved.

This observation indicates a limited variability of specific interactions between the vRNPs, but argues against a strict, non-variable sequence of vRNP interactions consistent with recent experimental and modelling reports 14, ... During transcription elongation, backtracking of RNAP is seen especially at transcript pause sites 1,11,12,18 .

 |  A thorough understanding of these problems is very important in the development of various application techniques that exploit the effects of confinement and stretching on polymers, including genome mapping [15,16], DNA sorting [17], and DNA denaturation mapping [18, ... Interestingly, a mutation in the viral RNA polymerase that reduced production and subsequent accumulation of D-RNAs was associated with increased influenza disease severity in both humans and mice (18); further, virus isolates from humans with severe IAV infection outcomes contained smaller amounts of D-RNAs than those from mild outcomes. 50% are in their 50s, while the average age is 50.

FEBS Lett. Clarendon Laboratory 1a). Influenza virus intimately associates with host RNA polymerase II (Pol II) and mRNA processing machinery. This site needs JavaScript to work properly. Recent studies have demonstrated that cellular stress can disrupt normal transcription termination, leading to aberrant transcription of intergenic regions downstream of canonical termination sites (termed readthrough transcription or downstream of gene [DoG] transcription) through an unknown mechanism (pictured in Fig. We use an improved single-molecule denaturation mapping approach to detect repetitive elements and known as well as unique structural variation.

Mutagenic Analysis of Hazara Nairovirus Nontranslated Regions during Single- and Multistep Growth Identifies both Attenuating and Functionally Critical Sequences for Virus Replication. Our data demonstrate that a redundant network of RNA-RNA interactions is required for vRNP packaging and virus growth. We propose that mvRNAs act as the main agonists of RIG-I during influenza virus infection. Positive Selection Drives Preferred Segment Combinations during Influenza Virus Reassortment. 2017 Aug 10;91(17):e00830-17. David L.V. Moving On Out: Transport and Packaging of Influenza Viral RNA into Virions. Disrupting the catenation of the chromosomes with Topoisomerase IIα significantly alters overall chromosome shape, suggesting that DNA catenation must be simultaneously maintained for correct chromosome condensation, and destroyed to complete sister chromatid disjunction. New levers are being discovered such as methods improving handling of Thermodynamically Ultra-Fastened (TUF) DNA. The RNA sensor retinoic acid-inducible gene I (RIG-I) plays an important role in sensing viral infection and initiating a signalling cascade that leads to interferon expression5.
