Summary
Melanoma cells self-destruct through apoptosis, regulated by pro- and anti-apoptotic molecules. Understanding these molecular pathways, including key regulators like p53 and TRAIL, offers potential therapeutic strategies for melanoma treatment.
Area of Science:
- Oncology
- Molecular Biology
- Cell Death Research
Background:
- Melanoma cell death involves programmed cell death (apoptosis).
- Apoptosis is regulated by a balance of positive (apoptotic) and negative (anti-apoptotic) molecular factors.
- Some molecules exhibit dual pro- or anti-apoptotic roles, adding complexity to melanoma cell death pathways.
Purpose of the Study:
- To review the key molecular components and mechanisms of apoptosis in melanoma.
- To discuss the therapeutic potential of apoptosis-related molecules in melanoma treatment.
- To identify future research directions in melanoma apoptosis.
Main Methods:
- Literature review of current knowledge on melanoma apoptosis.
- Analysis of molecular regulators of apoptosis, including pro- and anti-apoptotic factors.
- Discussion of therapeutic implications of identified molecular targets.
Main Results:
- Identified key pro-apoptotic molecules (e.g., p53, TRAIL) and anti-apoptotic molecules (e.g., Bcl-2, survivin).
- Highlighted molecules with dual roles (e.g., TRAF-2, c-Myc).
- Detailed the therapeutic potential of specific molecules like p53, Mcl-1, Bcl-X(L), TRAIL, NF-(K)B, PITSLRE kinases, interferons, and IAPs.
Conclusions:
- The molecular machinery of apoptosis in melanoma presents numerous targets for therapeutic intervention.
- Modulating apoptosis regulators like p53, TRAIL, and NF-(K)B shows promise for enhancing melanoma treatment efficacy.
- Further research is warranted to fully exploit the therapeutic potential of targeting apoptosis pathways in melanoma.

01:30Overview 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...

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.
01:17The 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...
