Insights

Fenretinide, a synthetic retinoid, shows anticancer potential by triggering programmed cell death (apoptosis) in tumor cells. Further research is needed to fully understand the complex mechanisms behind fenretinide-induced cell death.

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • Fenretinide is a synthetic retinoid with demonstrated anticancer properties in preclinical and clinical studies.
  • Its anticancer activity is linked to the induction of apoptosis in various cancer cell types.

Purpose of the Study:

  • To review and explore the mechanisms of fenretinide-induced apoptosis.
  • To identify poorly understood aspects of fenretinide's cell death pathways.

Main Methods:

  • Review of in vitro and animal studies on fenretinide's anticancer effects.
  • Analysis of signaling pathways involved in fenretinide-induced apoptosis, including reactive oxygen species, ceramide, and ganglioside GD3.

Main Results:

  • Fenretinide induces apoptosis through mechanisms often independent of retinoic acid receptor activation.
  • Key signaling molecules mediate fenretinide's apoptogenic activity, initiating the intrinsic mitochondrial pathway.

Conclusions:

  • Fenretinide is a potent inducer of apoptosis in cancer cells.
  • Further investigation into the precise molecular underpinnings of fenretinide-induced cell death is warranted.

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...

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...
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...
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.
Overview of Cell Death01:30

Overview of Cell Death

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 20th century...
Necrosis01:16

Necrosis

Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...
