Single Nucleotide Polymorphisms-SNPs

Single Nucleotide Polymorphisms-SNPs

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,...

G Protein-coupled Receptors

G Protein-coupled Receptors

G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

Area of Science:

Computational biology
Drug discovery
Virology

Background:

The COVID-19 pandemic necessitated rapid identification of effective treatments.
Existing drug repurposing efforts have yielded limited FDA-approved therapies.

Purpose of the Study:

To develop and apply a computational pipeline for prioritizing repurposable drugs against COVID-19.
To validate prioritized drug candidates using multiple lines of evidence.

Main Methods:

Constructed a comprehensive COVID-19 knowledge graph integrating virus-host interactions, pathways, drugs, and phenotypes.
Employed deep graph neural networks to derive drug representations from biological interactions.
Prioritized drugs based on clinical trial history and validated using in vitro and population-based data.

Main Results:

Identified 22 high-priority candidate drugs for COVID-19 treatment, including Azithromycin, Atorvastatin, Aspirin, Acetaminophen, and Albuterol.
Discovered potential synergistic drug combinations for enhanced COVID-19 targeting.
Demonstrated the efficacy of the integrated approach in rapidly identifying therapeutic candidates.

Conclusions:

The developed pipeline effectively integrates biological interactions, deep learning, and multi-evidence validation for accelerated drug discovery.
This strategy facilitates the rapid identification of promising drug candidates and combinations for COVID-19 treatment.
The findings provide a foundation for further clinical investigation of prioritized therapeutics.
