Genetic Screens02:46

Genetic Screens

4.6K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Pharmacogenomics: Identification of New Drug Targets

121
Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...

Area of Science:

  • Virology
  • Molecular Biology
  • Infectious Diseases

Background:

  • Rotavirus (RV) is a major cause of severe diarrhea in infants and animals globally.
  • Research was historically limited by challenges in RV reverse genetics due to its complex genome and poor cell culture adaptation.
  • Early helper virus-dependent systems (2006) showed low efficiency.

Purpose of the Study:

  • To review the evolution of rotavirus reverse genetics systems.
  • To highlight key technological advancements and their impact.
  • To discuss applications and future prospects.

Main Methods:

  • Narrative review of scientific literature.
  • Analysis of technological milestones in rotavirus reverse genetics.
  • Discussion of system optimizations, including plasmid-based systems, codon modification, and CRISPR/Cas9 integration.

Main Results:

  • A breakthrough in 2017 established the first fully plasmid-based system, eliminating helper viruses.
  • Subsequent optimizations have dramatically increased system efficiency for diverse RV strains.
  • Reverse genetics is now a viable tool for RV research.

Conclusions:

  • Rotavirus reverse genetics has transformed the field, enabling detailed viral gene function analysis.
  • This technology is crucial for developing novel vaccines and antiviral drugs.
  • Future applications include investigating cross-species transmission and refining therapeutic strategies.
