Genetic Screens02:46

Genetic Screens

5.7K
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...

Classification of Elements and Compounds02:54

Classification of Elements and Compounds

73.1K
Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond. Elements are classified as atomic or molecular based on the nature of their basic units.
Compounds are pure substances composed of two or more elements in fixed, definite proportions. Compounds are classified as ionic or molecular (covalent) based on the bonds...

Microtubules01:35

Microtubules

99.1K
There are three types of cytoskeletal structures in eukaryotic cells—microfilaments, intermediate filaments, and microtubules. With a diameter of about 25 nm, microtubules are the thickest of these fibers. Microtubules carry out a variety of functions that include cell structure and support, transport of organelles, cell motility (movement), and the separation of chromosomes during cell division.

CRISPR01:59

CRISPR

57.9K
Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced...

The Nucleolus02:55

The Nucleolus

10.4K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

Area of Science:

  • Neuroscience
  • Toxicology
  • Drug Discovery

Background:

  • Current in vitro cytotoxicity assays struggle to predict neurotoxicity and seizurogenic liabilities.
  • Limitations in predicting neural network disruptions lead to late-stage detection of adverse effects in vivo.
  • Significant time and financial resources are often invested before identifying these detrimental effects.

Purpose of the Study:

  • To develop a reliable, high-throughput in vitro method for assessing neurotoxic and seizure-inducing compound effects.
  • To enable early identification of liabilities during the drug discovery process.
  • To reduce late-stage failures in drug development.

Main Methods:

  • Utilized a 48-well microelectrode array (MEA) platform for in vitro screening.
  • Employed custom data analysis algorithms alongside commercial tools.
  • Analyzed spike file data from cryogenically preserved rat cortical neurons.

Main Results:

  • Successfully developed an in vitro screening tool capable of identifying neurotoxic and seizurogenic chemical entities.
  • Demonstrated the utility of MEA technology for detecting adverse neural effects.
  • Provided a method for early-stage assessment of compound safety.

Conclusions:

  • The developed MEA-based platform offers a promising solution for early detection of neurotoxicity and seizurogenic liabilities.
  • This high-throughput screening tool can significantly improve the efficiency of drug discovery.
  • Implementing this method can help mitigate risks associated with late-stage identification of adverse neural effects.
