Pharmacogenomics: Identification of New Drug Targets

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...

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...

Genomics

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Combination Therapies and Personalized Medicine

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Background:

Text mining aids in generating biomedical hypotheses by identifying novel disease-gene associations.
The original RaJoLink model focused on rare terms for hypothesis generation.
Current medical hypotheses often involve molecular entities and mechanisms.

Purpose of the Study:

To extend the RaJoLink rare-term model to incorporate proteins and genes.
To combine text mining with gene prioritization for enhanced hypothesis generation.
To identify gene-disease associations relevant to ovarian cancer.

Main Methods:

Developed an enhanced RaJoLink rare-term model integrating standardized vocabularies and a gene/protein network.
Applied text mining to MEDLINE abstracts for association discovery.
Utilized the STRING database for gene prioritization and validation.

Main Results:

Successfully identified known gene-disease associations in ovarian cancer.
Discovered potential novel gene-disease associations requiring further investigation.
Demonstrated the utility of the enhanced model in a specific cancer context.

Conclusions:

The enhanced RaJoLink model effectively combines text mining and gene prioritization.
This approach facilitates the discovery of significant gene-disease relationships.
The methodology shows promise for advancing biomedical hypothesis generation in oncology.
