Genetic Screens02:46

Genetic Screens

5.8K
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...

Animal Mitochondrial Genetics

9.3K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

What is Population Genetics?

64.9K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Area of Science:

  • Drug discovery and development
  • Chemical genetics
  • Genomics and personalized medicine

Background:

  • Genetic basis for many diseases, including monogenic disorders and cancers, is known, yet effective targeted therapies are often lacking.
  • High-throughput screening (HTS) and high-content analysis (HCA) are crucial technologies for discovering therapeutic small molecules and research tools.
  • Both target-based (reverse chemical genetics) and phenotype-based (forward chemical genetics) screening strategies are employed.

Purpose of the Study:

  • To introduce high-throughput screening (HTS) technology.
  • To highlight HTS contributions to drug and probe discovery for monogenic diseases and cancer.
  • To discuss the evolution and application of chemical genetics approaches.

Main Methods:

  • Review of high-throughput screening (HTS) methodologies, including target-based and phenotypic screening.
  • Discussion of high-content analysis (HCA) as an advanced HTS technique.
  • Exploration of synthetic lethal screening as a hybrid approach merging phenotype and target.

Main Results:

  • Successful examples of target-based drug discovery, such as transthyretin modulators for amyloidosis and Gleevec for chronic myelogenous leukemia.
  • Successful examples of phenotypic screening, including modulators for cystic fibrosis, spinal muscular atrophy, and histone deacetylase inhibitors for cancer.
  • Demonstration of HTS's versatility in identifying therapeutic leads and molecular probes.

Conclusions:

  • High-throughput screening (HTS) is a powerful platform for advancing the development of targeted therapies for genetic diseases and cancers.
  • Both reverse and forward chemical genetics approaches, along with synthetic lethality, offer distinct advantages in drug discovery.
  • Continued innovation in HTS technologies will accelerate the identification of novel treatments for unmet medical needs.
