Insights

Synthetic lethality (SL) offers a new anticancer therapy approach. The Syn-Lethality knowledge base systematically identifies human cancer-specific SL gene pairs to discover novel drug targets.

Area of Science:

  • Oncology
  • Genetics
  • Bioinformatics

Background:

  • Synthetic lethality (SL) is a promising strategy for targeted cancer therapy.
  • SL involves the combined mutation of two genes leading to cell death, while single mutations are tolerated.
  • Few SL interactions are known in human cancers, necessitating systematic discovery.

Purpose of the Study:

  • To present Syn-Lethality, the first integrative knowledge base for human cancer-specific SL interactions.
  • To facilitate the discovery of novel anticancer drug targets through SL interactions.
  • To provide a comprehensive resource for understanding SL in human cancer.

Main Methods:

  • Integration of experimentally verified human SL gene pairs into a network.
  • Inclusion of annotations for gene function, pathways, and molecular mechanisms.
  • Mapping of yeast SL genes from high-throughput screenings to orthologous human genes.
  • Development of a relational database with search and network visualization functionalities.

Main Results:

  • Creation of Syn-Lethality, a dedicated knowledge base for human cancer SL.
  • Integration of diverse data, including experimental findings and yeast orthologs.
  • Development of a user-friendly interface for data exploration and network analysis.

Conclusions:

  • The Syn-Lethality knowledge base significantly accelerates the identification of novel anticancer drug targets.
  • This resource provides a foundation for deeper understanding and exploitation of SL in human cancer therapy.
  • The database is available as a downloadable Java application for broader accessibility.

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...

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...

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

Cancer-Critical Genes II: Tumor Suppressor Genes

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...
