Apoptosis: the suicide solution in cancer treatment and chemoprevention

Insights

Inducing apoptosis selectively in cancer cells, including cancer stem cells and premalignant cells, offers a promising strategy for cancer treatment and prevention. This targeted approach aims to eradicate tumors while sparing normal cells.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Death Research

Background:

  • Cancer cells evade apoptosis, necessitating novel therapeutic strategies.
  • Cancer stem cells (CSCs) are crucial for tumor regeneration and metastasis.
  • Premalignant cells represent early-stage targets for cancer prevention.

Discussion:

  • Conventional chemotherapy and targeted agents can induce cancer cell death.
  • Selective induction of apoptosis in CSCs is achievable, sparing normal stem cells.
  • Cancer chemopreventive agents often exhibit pro-apoptotic effects.

Key Insights:

  • Targeting apoptotic pathways offers a route to selectively eliminate cancer cells.
  • Apoptosis induction in CSCs is a viable strategy for complete cancer eradication.
  • Selective apoptosis induction in premalignant and malignant cells has broad therapeutic potential.

Outlook:

  • Development of drugs that selectively induce apoptosis in cancer cells is a high priority.
  • Targeting CSCs could lead to more effective cancer treatments and cures.
  • Selective apoptosis induction holds promise for both cancer treatment and chemoprevention.

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.
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...
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...
Autophagic Cell Death01:18

Autophagic Cell Death

Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and pro-apoptotic...
Combination Therapies and Personalized Medicine02:50

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...

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...
