Genetic Screens

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...

DNA Microarrays

DNA Microarrays

Microarrays are high-throughput and relatively inexpensive assays that can be automated to analyze large quantities of data at a time. They are used in genome-wide studies to compare gene or protein expression under two varied conditions, such as healthy and diseased states. Microarrays consist of glass or silica slides on which probe molecules are covalently attached through surface functionalization. Most commonly, the slides are prepared through the chemisorption of silanes to silica...

Area of Science:

Bioinformatics
Computational Biology
Genomics

Background:

High-dimensional datasets, common in gene expression studies, require effective feature selection.
Gene selection aims to reduce noise, redundancy, improve classification, and aid biological validation.

Purpose of the Study:

To develop an improved hybrid system for gene selection from microarray data.
To enhance the generalization property and overcome overfitting in genetic ensemble (GE) systems.

Main Methods:

A novel mapping strategy fuses gene goodness information from multiple filtering algorithms.
This fused information is used to initialize and guide the mutation operations within a genetic ensemble system.
The proposed system is termed the multi-filter enhanced genetic ensemble (MF-GE).

Main Results:

The MF-GE system demonstrated improved sample classification accuracy on benchmark microarray datasets.
It generated more compact gene subsets compared to existing methods.
The system converged more quickly to selection results.

Conclusions:

The MF-GE system offers a flexible and effective approach to gene selection.
It can incorporate various filters and classifiers tailored to specific data characteristics and user needs.
The MF-GE system enhances biological insights by providing focused gene subsets.
