The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

6.2K
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

6.2K
The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...

Cancer-Critical Genes II: Tumor Suppressor Genes

8.3K
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...

Overview of Cell Death01:30

Overview of Cell Death

7.7K
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

Protein Networks02:26

Protein Networks

3.7K
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:

  • Molecular Biology
  • Cancer Research
  • Cell Death Pathways

Background:

  • Regulated cell death (RCD) involves molecular mechanisms to eliminate harmful cells.
  • Targeting RCD is a promising strategy in cancer therapy.

Purpose of the Study:

  • To investigate the role of cell death pathways in cancer therapy.
  • To identify essential genes within various RCD pathways.

Main Methods:

  • Analysis of 1150 cancer cell lines from the Dependency Map (DepMap) database.
  • Assessment of gene essentialities across 12 distinct cell death pathways.
  • Classification of genes as always essential, partial essential, or rare essential.

Main Results:

  • Identified 23 always essential, 47 partial essential, and 549 rare essential genes across 12 RCD pathways.
  • Parthanatos and Pyroptosis pathways exclusively contained rare essential genes.
  • Specific counts of partial and always essential genes were found in other pathways like Apoptosis and Necroptosis.

Conclusions:

  • Essential genes within cell death pathways represent potential therapeutic targets.
  • Drug development targeting these genes could enhance cancer therapies.
