Summary
Epigenetic modifications, which alter gene expression without changing DNA sequence, are increasingly recognized for their role in melanoma development. Aberrant epigenetic events like DNA methylation and histone modifications contribute to melanoma progression and gene dysregulation.
Area of Science:
- Oncology
- Molecular Biology
- Epigenetics
Background:
- Melanoma development is linked to genetic mutations and chromosomal abnormalities.
- Epigenetic events, which modify gene expression without altering DNA sequence, are gaining attention in melanoma progression.
- Normal development relies on epigenetic mechanisms like histone modifications and DNA methylation for proper gene expression.
Purpose of the Study:
- To review the role of epigenetic modifications in cancer, with a specific focus on melanoma.
- To explore how epigenetic dysregulation contributes to melanoma development and progression.
- To provide an overview of various epigenetic modifications involved in melanoma.
Main Methods:
- Literature review of epigenetic modifications and their role in melanoma.
- Analysis of studies reporting gene dysregulation through DNA methylation and histone modifications in melanoma.
- Synthesis of evidence on chromatin remodeling activities in melanoma progression.
Main Results:
- Aberrant DNA methylation has been reported to dysregulate at least 50 genes in melanoma.
- Mistargeting of histone modifications and altered chromatin remodeling are implicated in melanoma pathogenesis.
- Epigenetic alterations lead to aberrant gene expression patterns and loss of anti-cancer checkpoints.
Conclusions:
- Epigenetic modifications play a crucial role in melanoma development and progression, independent of DNA sequence changes.
- Understanding these epigenetic alterations is vital for developing novel therapeutic strategies against melanoma.
- Further research into epigenetic mechanisms can elucidate key drivers of melanoma and identify potential therapeutic targets.

01:37Epigenetic Regulation
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

01:06Induced Pluripotent Stem Cells
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

03:03mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
