Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

4.8K
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...

Cancer-Critical Genes I: Proto-oncogenes

8.6K
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...

Protein Networks02:26

Protein 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,...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.4K
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...

Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

5.7K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

    Area of Science:

    • Oncology
    • Computational Biology
    • Genetics

    Background:

    • Cancer driver genes are critical for targeted therapy, but current methods often overlook patient-specific variations and complex gene interactions.
    • Existing computational approaches typically generate a single list of driver genes, failing to capture the heterogeneity of cancer across individuals.
    • Identifying higher-order gene interactions at the patient level is essential for accurate driver gene discovery.

    Purpose of the Study:

    • To introduce PITCH, a novel computational method for prioritizing personalized cancer driver genes.
    • To assess higher-order gene propagation dynamics for a more comprehensive understanding of cancer development.
    • To develop a tool that simplifies the identification of actionable therapeutic targets for personalized cancer treatment.

    Main Methods:

    • PITCH utilizes a patient-specific hypergraph model to represent complex, higher-order gene interactions within signaling pathways.
    • The method assesses gene influence by analyzing propagation dynamics within the constructed hypergraph.
    • PITCH does not require paired case-control data, facilitating easier clinical application.

    Main Results:

    • PITCH demonstrated superior performance in identifying cancer driver genes across four cancer types compared to existing methods.
    • The method successfully identified both common and rare driver genes, validated against established cancer gene databases.
    • A significant proportion of PITCH-identified personalized driver genes were found to be actionable and druggable.

    Conclusions:

    • PITCH offers a significant advancement in cancer driver gene discovery by accounting for patient-specific heterogeneity and higher-order gene interactions.
    • The method provides a powerful tool for precise identification of therapeutic targets, supporting the development of personalized cancer treatment strategies.
    • PITCH's ability to identify actionable and druggable genes holds substantial potential for improving clinical outcomes in cancer therapy.
