Summary
Apoptosis, programmed cell death, is crucial for eliminating damaged cells. Understanding how cancer cells evade apoptosis offers new therapeutic targets for improved cancer treatment strategies.
Area of Science:
- Molecular Biology
- Cell Biology
- Oncology
Background:
- Apoptosis, or programmed cell death, is a fundamental physiological process essential for removing damaged or superfluous cells.
- Dysregulation of apoptosis is implicated in tumor development and resistance to cancer therapies.
Purpose of the Study:
- To provide a comprehensive overview of recent advancements in understanding apoptosis within human cancer cells.
- To explore the molecular mechanisms underlying apoptosis and its deregulation in cancer.
Main Methods:
- This review synthesizes recent research findings on the molecular network regulating apoptosis.
- Analysis of signaling, commitment, and execution pathways involved in programmed cell death.
Main Results:
- The human apoptotic machinery involves a complex protein network regulating multiple parallel pathways.
- Deregulation of these pathways contributes to cancer formation and therapy resistance.
- Therapeutic strategies targeting apoptosis are being developed to selectively eliminate tumor cells.
Conclusions:
- Elucidating the fundamental mechanisms of apoptosis is key to identifying novel molecular targets.
- Understanding how cancer cells evade apoptosis will pave the way for more effective cancer therapies.

01:30Apoptosis
16.1K
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...

01:31The Intrinsic Apoptotic Pathway
8.9K
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...

01:17The Extrinsic Apoptotic Pathway
9.0K
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...

01:17Phagocytosis of Apoptotic Cells
5.4K
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.

01:30Overview of Cell Death
10.6K
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...

01:18Autophagic Cell Death
4.7K
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.
