Protein Networks

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,...

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...

In-vitro Mutagenesis

In-vitro Mutagenesis

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.

Gene Therapy

Gene Therapy

Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Targeted Cancer Therapies

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Background:

Whole transcriptome profiling is crucial for understanding clinical phenotypes and disease subtypes.
Sophisticated analyses now explore higher-order interactions within gene regulatory networks (GRNs).
GRNs model transcription factor-gene relationships, aiding in identifying differentially regulated disease processes.

Purpose of the Study:

To introduce and discuss gene targeting scores as a method to measure changes in inferred GRN interactions.
To demonstrate the utility of gene targeting scores in identifying disease-relevant processes.
To showcase the application of gene targeting scores in characterizing complex phenotypes using pancreatic ductal adenocarcinoma (PDAC) as an example.

Main Methods:

Gene targeting scores were developed to quantify alterations in inferred gene regulatory network interactions.
A case study involving pancreatic ductal adenocarcinoma (PDAC) was analyzed using gene targeting scores.
Differential expression analysis was performed for comparison with gene targeting score analysis.

Main Results:

Gene targeting scores successfully identified differential processes between complex phenotypes in PDAC.
These identified processes were not detectable through differential expression analysis alone.
The analysis highlighted the power of gene targeting scores in uncovering subtle biological differences.

Conclusions:

Gene targeting scores are a valuable addition to gene expression analysis.
This method provides deeper insights into disease characterization and complex phenotypes.
Gene targeting scores enhance the identification of disease-relevant biological processes.
