Full-length poliovirus complementary DNA (cDNA) was synthesized by assembling oligonucleotides of plus and minus strand polarity. The synthetic poliovirus cDNA was transcribed by RNA polymerase into viral RNA, which translated and replicated in a cell-free extract, resulting in the de novo synthesis of infectious poliovirus. Experiments in tissue culture using neutralizing antibodies and CD155 receptor–specific antibodies and neurovirulence tests inCD155 transgenic mice confirmed that the… Expand

Production of infectious poliovirus from synthetic viral genomes.
TLDR
This work shows that it is possible to synthesize an infectious agent in test tube by solely following instructions from a written sequence by synthesizing synthetic deoxyoligonucleotides. Expand
Total chemical synthesis, assembly of human torque teno virus genome
TLDR
This study completely synthesized the 3 808 nucleotides of the TTV (SANBAN isolate) genome, which contains a hairpin structure and a GC-rich region. Expand
Synthetic poliovirus and other designer viruses: what have we learned from them?
TLDR
The first synthesis of a virus in 2002 is described, which shaped the response to de novo syntheses of other viruses and those viruses that have been synthesized since 2002, among them viruses whose precise genome sequence had to be established by painstakingly stitching together pieces of sequence information. Expand
Proof by synthesis of Tobacco mosaic virus
TLDR
This first report of the chemical synthesis and artificial assembly of a plant virus corrects a long-standing error in the TMV reference genome sequence and reveals that unnatural hybrid virus proteins can alter symptoms unexpectedly. Expand
Chemical Synthesis of Bacteriophage G4
TLDR
This study demonstrated that a phage can be synthesized and manipulated genetically according to the sequences, and can be efficient enough to infect the Escherichia coli, showing the potential use of synthetic biology in medical application. Expand
An inactivated West Nile Virus vaccine derived from a chemically synthesized cDNA system
TLDR
It is demonstrated that virus isolates from animal sources are dispensable to derive seed viruses for vaccine production or research and the first flavivirus based on chemical gene synthesis was indistinguishable from the parent virus. Expand
Reduction of the Rate of Poliovirus Protein Synthesis through Large-Scale Codon Deoptimization Causes Attenuation of Viral Virulence by Lowering Specific Infectivity
TLDR
Direct analysis indicated a striking reduction of the specific infectivity of PV-AB-type virus particles, suggesting that codon-deoptimized viruses should have genetically stable phenotypes, and they may prove suitable as attenuated substrates for the production of poliovirus vaccines. Expand
Synthetic viruses: a new opportunity to understand and prevent viral disease
TLDR
Although only a few applications of virus synthesis have been described as yet, key recent findings have been the resurrection of the 1918 influenza virus and the generation of codon- and codon pair–deoptimized polioviruses. Expand
Identification of two functionally redundant RNA elements in the coding sequence of poliovirus using computer-generated design
  • Y. Song, Y. Liu, +5 authors E. Wimmer
  • Biology, Computer Science
  • Proceedings of the National Academy of Sciences
  • 2012
TLDR
Recoding offers a unique and effective method to search for unknown functional RNA elements in coding sequences of RNA viruses, particularly if the signals are redundant in function. Expand
Cell-free bacteriophage genome synthesis using low cost sequence-verified array-synthesized oligonucleotides.
TLDR
A cell-free, low-cost de novo gene synthesis technology called Sniper assembly for phage genome construction, which lowered the genome synthesis cost ($0.0137/bp) by producing low- cost sequence-verified DNA. Expand

Cell-free, de novo synthesis of poliovirus.
TLDR
Cell-free translation of poliovirus RNA in an extract of uninfected human (HeLa) cells yielded viral proteins through proteolysis of the polyprotein, which will aid in the study of picornavirus proliferation and in the search for the control of picORNaviral disease. Expand

TLDR
The complete 7410 nucleotide sequence of poliovirus type I genome was obtained from cloned cDNA was synthesized and inserted into the Pst I site of plasmid pBR322, and three clones were derived that together provided DNA copies of the entire poliov virus genome. Expand
Cellular receptor for poliovirus: Molecular cloning, nucleotide sequence, and expression of a new member of the immunoglobulin superfamily
TLDR
Northern hybridization analysis indicates that poliov virus receptor transcripts are expressed in a wide range of human tissues, in contrast to the limited expression of virus binding sites, which suggests that additional factors or modifications of the receptor protein are required to permit poliovirus attachment. Expand
Primary structure, gene organization and polypeptide expression of poliovirus RNA
TLDR
The primary structure of the poliovirus genome has been determined and Twelve viral polypeptides have been mapped by amino acid sequence analysis and were found to be proteolytic cleavage products of the polyprotein, cleavages occurring predominantly at Gln-Gly pairs. Expand
Genetic analysis of an NTP-binding motif in poliovirus polypeptide 2C.
TLDR
Viral RNA synthesis is greatly reduced but not entirely abolished in cells transfected with mutant RNAs, suggesting a functional role for the proposed NTP-binding motif of 2C in RNA replication and proliferation of poliovirus. Expand
The poliovirus receptor protein is produced both as membrane‐bound and secreted forms.
TLDR
Predicted amino acid sequences indicate that PVR alpha and PVR delta, corresponding to the previously described cDNA clones H20A and H20B, respectively, are integral membrane proteins while the other two molecules described here for the first time lack a putative transmembrane domain. Expand
Internal initiation of translation of eukaryotic mRNA directed by a sequence derived from poliovirus RNA
TLDR
A novel mechanism of initiation on poliovirus RNA occurs by binding of ribosomes to an internal sequence within the 5′ noncoding region, which may explain the disparate translation of several other eukaryotic messenger RNAs. Expand
A segment of the 5' nontranslated region of encephalomyocarditis virus RNA directs internal entry of ribosomes during in vitro translation
TLDR
The sequence between nucleotides 260 and 484 in the 5'NTR of encephalomyocarditis RNA was found to play a critical role in the efficient translation in both mono- and dicistronic mRNAs, and data suggest that an internal ribosomal entry site resides in this region. Expand
Production of a monoclonal antibody against an epitope on HeLa cells that is the functional poliovirus binding site.
TLDR
Results indicate that D171 recognizes the poliov virus receptor site on different susceptible cells and that practically all D171 binding sites are involved in the specific attachment of poliovirus to the plasma membrane. Expand
