Genetic Screens02:46

Genetic Screens

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 result in visible changes...
Protein Networks02:26

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...
Genome Annotation and Assembly03:36

Genome Annotation and Assembly

The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.
Pharmacogenomics: Identification of New Drug Targets01:29

Pharmacogenomics: Identification of New Drug Targets

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:

  • Genomics
  • Systems Biology
  • Bioinformatics

Background:

  • Identifying genes crucial for biological processes or diseases is a significant challenge for biologists and clinicians.
  • Experimental data for gene importance prediction is often fragmented across various sources with inconsistent quality.

Purpose of the Study:

  • To introduce integrated functional gene networks as a method to consolidate dispersed biological data.
  • To demonstrate how these networks enhance the prediction of gene functions and associations.

Main Methods:

  • Developing an approach to measure the predictive ability of individual datasets using a standard benchmark.
  • Combining scored predictions from multiple datasets to create a unified probabilistic gene network.

Main Results:

  • Integrated gene networks offer greater coverage and accuracy in predicting gene function compared to individual datasets.
  • The review highlights the construction and validation of these networks, using Caenorhabditis elegans as a model system.

Conclusions:

  • Integrated gene networks provide a powerful tool for experimental biologists to guide research and predict gene function.
  • This approach is broadly applicable and holds promise for dissecting the genetics of complex human diseases.
