In-vitro Mutagenesis01:16

In-vitro Mutagenesis

15.9K
To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

Genetic Screens02:46

Genetic Screens

5.5K
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...

In Vitro Fertilization01:24

In Vitro Fertilization

820
In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

Area of Science:

  • Genetics
  • Systems Biology
  • Molecular Biology

Background:

  • Dissecting complex traits is challenging.
  • Traditional genetics approaches (forward and reverse) study gene expression signatures of quantitative trait loci and candidate genes.
  • In vivo studies are limited in many species.

Purpose of the Study:

  • Propose an in vitro method for complex trait dissection.
  • Demonstrate the relevance of in vitro approaches to whole organisms.
  • Enable rapid and effective complex trait analysis in diverse species.

Main Methods:

  • Utilize cell-line-based connectivity maps.
  • Analyze gene expression signatures from natural variation.
  • Employ induced perturbations, such as RNA interference (RNAi).

Main Results:

  • Gene signatures are conserved across tissues and species.
  • In vitro approaches are relevant to whole-organism biology.
  • Cell-line-based methods show promise for complex trait dissection.

Conclusions:

  • In vitro gene expression studies provide a rapid and effective method for dissecting complex traits.
  • This approach is applicable to a wide range of species, including humans.
  • Cell-line-based connectivity maps enhance the understanding of gene function and regulation in complex traits.
