Summary
Synthetically lethal relationships (SSLs) between gene pairs offer cancer treatment opportunities. Researchers identified mutually exclusive gene pairs, focusing on drug-targetable genes for potential cancer therapies.
Area of Science:
- Genomics
- Cancer Biology
- Pharmacology
Background:
- Mutually exclusive gene alterations suggest synthetic lethal relationships (SSLs).
- SSLs represent a promising therapeutic strategy for selective cancer cell killing.
- Identifying SSLs can reveal novel drug targets and reposition existing drugs.
Purpose of the Study:
- To identify mutually exclusive gene pairs associated with synthetic lethality.
- To discover potential targeted therapeutics by focusing on drug-targetable genes.
- To explore drug repositioning opportunities for various cancers.
Main Methods:
- Analysis of mutation, copy number variation, and methylation data from The Cancer Genome Atlas.
- Application of hypergeometric and Poisson binomial tests to identify gene pair exclusivity.
- Focus on gene pairs involving inactivated tumor suppressors and drug-targetable genes.
Main Results:
- Identification of numerous mutually exclusive gene pairs across cancer samples.
- Discovery of potential therapeutic targets within these gene pairs.
- Highlighting opportunities for drug repositioning in cancer treatment.
Conclusions:
- Mutually exclusive gene alterations can indicate synthetic lethality exploitable for cancer therapy.
- The study provides a resource for identifying targeted therapies and drug repositioning.
- Data is accessible via the MexDrugs website for further research.

7.4K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

02:26Protein Networks
3.9K
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,...

02:50Combination Therapies and Personalized Medicine
4.9K
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...

01:12Loss of Tumor Suppressor Gene Functions
4.8K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

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.
