Insights

Anticancer drugs trigger apoptosis (programmed cell death) in cancer cells. Understanding apoptosis pathways is key to overcoming drug resistance and developing new cancer therapies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Biology

Background:

  • Accumulating evidence shows anticancer agents induce apoptosis in cancer cells.
  • Abnormalities in apoptosis signaling pathways are common in cancer and linked to drug resistance.
  • Apoptosis regulators are critical for tumor sensitivity to chemotherapy and potential therapeutic targets.

Purpose of the Study:

  • To review recent advancements in understanding apoptosis in cancer.
  • To explore strategies for exploiting apoptosis pathways for selective tumor cell death.
  • To address the role of oncogenic signals in cancer cell apoptosis susceptibility.

Main Methods:

  • Literature review of recent progress in cancer apoptosis research.
  • Analysis of evidence on antitumour agents and apoptosis induction.
  • Examination of alterations in apoptosis signaling pathways in tumors.

Main Results:

  • Anticancer agents effectively induce apoptosis in malignant cells.
  • Defects in apoptosis pathways are often acquired during cancer development.
  • Oncogenic signals can increase cancer cell susceptibility to apoptosis.

Conclusions:

  • Targeting apoptosis pathways offers a rational strategy for novel anticancer agents.
  • Identifying specific apoptosis pathway alterations is crucial for effective cancer treatment.
  • Exploiting apoptosis mechanisms can lead to selective tumor cell death.

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...

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.

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...
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.
