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...

Genome-wide Association Studies-GWAS

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...

Combinatorial Gene Control

Combinatorial Gene Control

Combinatorial gene control is the synergistic action of several transcriptional factors to regulate the expression of a single gene. The absence of one or more of these factors may lead to a significant difference in the level of gene expression or repression.
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...

Area of Science:

Computational biology
Cancer informatics
Genomics

Background:

Identifying cancer driver genes is crucial for understanding cancer progression.
Current methods often focus on individual genes, potentially overlooking collaborative effects.
Cancer development may involve coordinated actions of multiple genes rather than single gene dysregulation.

Purpose of the Study:

To develop a novel computational method for detecting cancer driver gene groups.
To investigate the hypothesis that groups of genes act in concert to drive cancer.
To provide a tool for identifying coordinated genetic alterations in cancer.

Main Methods:

Developed DriverGroup, a computational method utilizing gene expression and interaction data.
The method involves constructing gene networks, identifying critical nodes, and detecting driver gene groups.
Performance was validated using DREAM4 data for gene group influence and the BRCA dataset for breast cancer driver groups.

Main Results:

DriverGroup demonstrated superior effectiveness in detecting gene group regulation compared to existing methods on DREAM4 data.
Application to the BRCA dataset identified promising driver gene groups, with several members linked to cancer in literature.
Survival analysis using identified driver groups showed significant differentiation in patient subpopulation outcomes.

Conclusions:

DriverGroup is an effective method for identifying cancer driver gene groups.
The identified driver gene groups have potential clinical relevance and prognostic value in breast cancer.
This approach advances the understanding of cooperative gene functions in cancer development.
