Insights

Apoptosis, a key evolutionary process for eliminating damaged cells, may paradoxically aid tumor progression. Tumors can exploit apoptosis to eliminate less aggressive cells, promoting the survival of highly malignant clones.

Area of Science:

  • Cell Biology
  • Evolutionary Biology
  • Cancer Biology

Context:

  • Apoptosis (programmed cell death) is an evolutionary mechanism to remove damaged or obsolete cells, crucial for controlling neoplastic processes.
  • Clinical observations suggest apoptosis can have an inverse effect in cancer, contradicting its role in tumor suppression.
  • Fundamental studies using light and electron microscopy reveal disruptions in the physiological process of apoptosis.

Purpose:

  • To investigate the paradoxical role of apoptosis in cancer progression.
  • To elucidate the mechanisms by which tumors may subvert apoptosis.
  • To understand how apoptosis disturbances contribute to tumor evolution and malignancy.

Summary:

  • This research reveals that tumors can manipulate apoptosis to their advantage.
  • Apoptosis can be co-opted by cancer cells to eliminate less malignant cell populations.
  • This selective elimination process facilitates the self-selection of highly aggressive tumor clones with maximum malignant potential.

Impact:

  • Understanding how tumors exploit apoptosis offers new insights into cancer progression.
  • Identifying these subverted apoptotic pathways could reveal novel therapeutic targets.
  • This work challenges the traditional view of apoptosis solely as a tumor suppressor mechanism.

Apoptosis01:30

Apoptosis

Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size reduction of the tissue.
Caspases01:24

Caspases

Caspase, a family of cysteine proteases, serve as effectors in apoptosis. The ced3 gene in C.elegans was first identified to be involved in apoptosis. This gene encodes the ced-3 caspase that is similar to the interleukin-1-beta converting enzyme or ICE in mammals. In addition to apoptosis, caspases also function in the inflammatory response. Inflammatory caspases are essential in activating pro-inflammatory cytokines that recruit immune cells and block the replication of pathogens inside cells.
The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

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...
The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

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...
Phagocytosis of Apoptotic Cells01:17

Phagocytosis of Apoptotic Cells

Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or  immature dendritic cells. Non-professional phagocytes such as  epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes. 
Normal cells contain receptors that prevent them from being recognized by phagocytes.
Cellular Injury V: Apoptosis and Autophagy01:22

Cellular Injury V: Apoptosis and Autophagy

Cells respond to damage and stress through highly coordinated processes that decide whether they survive or undergo controlled self-destruction. Two major pathways involved in this regulation are apoptosis, a type of programmed cell death, and autophagy, a survival mechanism that helps cells adapt to adverse conditions.ApoptosisApoptosis removes aged or injured cells to maintain tissue balance. During this process, the cell shrinks, chromatin condenses and fragments, and membrane-bound...
