Combination Therapies and Personalized Medicine

5.1K
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...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.9K
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...

Protein Networks02:26

Protein Networks

4.1K
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,...

Area of Science:

  • Biomedical Informatics
  • Computational Biology
  • Drug Discovery

Background:

  • 'De novo' drug discovery is expensive, slow, and high-risk.
  • Drug repurposing offers a faster, cheaper, and more efficient alternative.
  • Emerging large-scale biological data enables computational drug repurposing (CDR).

Purpose of the Study:

  • To address challenges in traditional CDR, particularly capturing complex, non-linear drug-disease-gene associations.
  • To develop a network-based integration approach for CDR.
  • To identify potential therapeutic drugs for various breast cancer subtypes using CDR.

Main Methods:

  • Integrated heterogeneous biomolecular, chemical, bioactivity, genomic, and phenotypic data.
  • Applied a network-based machine learning approach to capture complex relationships.
  • Utilized the network approach to identify drugs for specific breast cancer subtypes.

Main Results:

  • Successfully captured complex, non-linear associations among drugs, genes, and diseases.
  • Identified single and pairs of approved or experimental drugs with potential therapeutic effects.
  • The identified drugs show promise for treating different breast cancer subtypes.

Conclusions:

  • The proposed network-based integration approach enhances CDR by effectively modeling complex biological relationships.
  • This method facilitates the discovery of novel therapeutic strategies for breast cancer.
  • Further clinical validation is required to confirm the efficacy of the identified drugs.
