Summary
Vitamin E (tocopherol) acts as an antioxidant, influencing apoptosis through multiple complex mechanisms. These include caspase activation, mitochondrial processes, and interactions with tocopherol-binding proteins.
Area of Science:
- Biochemistry
- Cell Biology
- Molecular Biology
Context:
- Apoptosis, or programmed cell death, is a fundamental biological process.
- Tocopherol (Vitamin E) is a well-known antioxidant with diverse cellular functions.
- Understanding the role of antioxidants in cell death pathways is crucial for disease research.
Purpose:
- To review and discuss the existing literature on the role of tocopherol in apoptosis.
- To elucidate the multifaceted mechanisms by which tocopherol influences apoptotic processes.
- To highlight the complex interplay between antioxidant activity and programmed cell death.
Summary:
- Tocopherol exerts a complex, multifaceted effect on apoptosis mechanisms, acting beyond its primary antioxidant role.
- Its influence on apoptosis involves various signaling pathways, including caspase and Fas-receptor activation.
- Key cellular components such as nuclei, mitochondria, and sphingolipid metabolism are implicated in tocopherol's apoptotic effects.
- Specific interactions with tocopherol-binding proteins may also mediate its action on programmed cell death.
Impact:
- Provides a comprehensive overview of tocopherol's involvement in apoptosis for researchers.
- Identifies critical molecular targets and pathways affected by tocopherol in cell death.
- Offers insights into potential therapeutic strategies involving Vitamin E in diseases associated with apoptosis dysregulation.

01:30Apoptosis
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.
01:24Caspases
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.
01:17The 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...
01:31The 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...
01:17Phagocytosis 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.

01:22Cellular 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...
