Zika Virus Subgenomic Flavivirus RNA Generation Requires Cooperativity between Duplicated RNA Structures That Are Essential for Productive Infection in Human Cells
TLDR
It is found that two RNA structures of the viral 3′ UTR operate in a cooperative manner to produce two species of sfRNAs and that the deletion of these elements has a profoundly different impact on viral replication in the two hosts.
Zika virus noncoding RNA suppresses apoptosis and is required for virus transmission by mosquitoes
TLDR
It is shown that sfRNA affects virus-induced apoptosis and dissemination of ZIKV in Aedes aegypti mosquitoes, suggesting a role of sf RNA in Zika virus replication and transmission.
Inhibition of Zika Virus Replication by Silvestrol
TLDR
In both infected A549 cells and primary human hepatocytes, silvestrol has the potential to exert a significant inhibition of ZIKV replication for both analyzed strains, even though the ancestor strain from Uganda is less sensitive tosilvestrol.
Biochemistry and Molecular Biology of Flaviviruses.
TLDR
This review examines the molecular biology of flaviviruses touching on the structure and function of viral components and how these interact with host factors, and highlights the role of a noncoding RNA produced by flavIViruses to impair antiviral host immune responses.
Circularization of flavivirus genomic RNA inhibits de novo translation initiation
TLDR
This work demonstrates that circularization inhibits de novo translation initiation on ZIKV and DENV RNA, whilst the linear conformation is translation-competent and defines opposing roles for linear and circular conformations of the flavivirus genome.
The dinucleotide composition of the Zika virus genome is shaped by conflicting evolutionary pressures in mammalian hosts and mosquito vectors
TLDR
The evolutionary pressure on the CpG dinucleotides of viral genomes in arthropod vectors directly opposes the pressure present in vertebrate host cells, which provides evidence that an adaptive compromise is required for arbovirus transmission.
Zika virus: Molecular responses and tissue tropism in the mammalian host
TLDR
An update on ZikV research models and mammalian host responses with respect to ZIKV tissue infection is provided.
Zika virus: A review article
Zika virus, a flavivirus which is spread by Aedes mosquitoes, was considered as innocent pathogen while restricted to the African and Asian population. However, after reaching the Americas in March
Evasion of Innate and Intrinsic Antiviral Pathways by the Zika Virus
TLDR
This work describes emerging evidence that indicated the contribution of several cell-intrinsic mechanisms to an effective restriction of ZIKV infection, such as nonsense-mediated mRNA decay, stress granule formation, and “reticulophagy”, a type of selective autophagy.
Evaluation of Conserved RNA Secondary Structures within and between Geographic Lineages of Zika Virus
TLDR
This work proposes these structures as candidates for further experimental validation to establish their potential role in vital functions of the viral cycle of ZIKV and their possible associations with the singularities of different outbreaks that lead to ZikV populations to acquire nucleotide substitutions, which is evidence of the local structure genome differentiation.

Nucleotide composition of the Zika virus RNA genome and its codon usage
TLDR
The ZIKV RNA genome has a biased nucleotide composition that dictates the codon usage of this flavivirus, which is a general characteristic of the mosquito-borne and tick-borne flaviviruses.

The results of the present study suggest a novel role for sfRNA, i.e., as a nucleic acid-based regulator of RNAi pathways, a strategy that may be conserved among flaviviruses.
