Summary
Researchers identified a drug, IMD-0354, that reverses host gene expression changes caused by SARS-CoV-2 infection and its variants. This approach aids in discovering new antiviral therapies for evolving coronaviruses.
Area of Science:
- Virology
- Genomics
- Pharmacology
Background:
- Host cell responses to SARS-CoV-2 and its variants vary significantly, complicating host-based antiviral drug discovery.
- Antiviral drugs are hypothesized to counteract viral infection by reversing global host gene expression patterns.
Purpose of the Study:
- To identify host transcriptomic signatures of coronavirus infection and evaluate their potential for therapeutic discovery.
- To discover novel antiviral compounds effective against SARS-CoV-2 and its variants using a transcriptomic reversal approach.
Main Methods:
- Retrospective analysis of 1,700 host transcriptomic profiles from SARS, MERS, and SARS-CoV-2 infections.
- Iterative, data-driven evaluation of gene expression signatures to identify those reversible by antiviral agents.
- In vitro testing of candidate compounds, including IMD-0354, against SARS-CoV-2 and its variants.
Main Results:
- Identified conserved coronavirus infection signatures across different host models and conditions.
- Discovered IMD-0354, a compound that globally reverses host gene expression signatures with nanomolar IC50 values against SARS-CoV-2 and five variants.
- IMD-0354 demonstrated antiviral activity by stimulating type I interferon response, inhibiting viral entry, and reducing viral protein hijacking.
Conclusions:
- The transcriptomic reversal approach, leveraging conserved coronavirus signatures and polypharmacology, is a viable strategy for discovering new antiviral therapeutics.
- IMD-0354 shows significant promise as a broad-spectrum antiviral agent against SARS-CoV-2 and its evolving variants.

5.2K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

01:05Single Nucleotide Polymorphisms-SNPs
15.6K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

00:36Viral Mutations
32.8K
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

3.6K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
