Insights

Inhibition of programmed cell death (PCD) is crucial for cancer development. Restoring these natural cell death processes offers a promising new avenue for cancer therapy.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Biology

Background:

  • Programmed cell death (PCD) is a critical biological process that eliminates unwanted or damaged cells.
  • Dysregulation of PCD is increasingly recognized as a significant factor in the development and progression of cancer.
  • Many cancer-promoting mutations target and disrupt the molecular pathways governing PCD.

Purpose of the Study:

  • To review the genes and molecular mechanisms underlying programmed cell death (PCD).
  • To summarize the evidence linking impaired PCD to tumorigenesis.
  • To explore the therapeutic potential of restoring defective PCD pathways in cancer treatment.

Main Methods:

  • Literature review of genes and mechanisms involved in PCD.
  • Analysis of evidence supporting the role of impaired PCD in cancer.
  • Discussion of therapeutic strategies targeting PCD.

Main Results:

  • Programmed cell death (PCD) is a fundamental process that, when inhibited, contributes significantly to cancer.
  • Numerous genetic mutations found in tumors directly interfere with PCD pathways.
  • Evidence strongly suggests that defective PCD is a necessary step for cancer to arise.

Conclusions:

  • Inhibition of programmed cell death (PCD) is a key hallmark of cancer.
  • Understanding the molecular basis of PCD is essential for cancer research.
  • Targeting and restoring 'death programs' represents a novel and promising strategy for cancer therapy.

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.
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...

Negative Regulator Molecules

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.
Loss of Tumor Suppressor Gene Functions01:12

Loss of Tumor Suppressor Gene Functions

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
