Summary
Epigenetic mechanisms, particularly DNA methylation, play a crucial role in skin disease development. Aberrant DNA methylation is linked to various skin conditions, highlighting its pathogenic significance.
Area of Science:
- Molecular Biology
- Dermatology
- Epigenetics
Background:
- Epigenetic mechanisms regulate gene expression without altering DNA sequence.
- Key mechanisms include DNA methylation, histone modification, and microRNA.
- Aberrant DNA methylation is implicated in numerous human disorders, including various skin diseases.
Purpose of the Study:
- To review the role of DNA methylation in the pathogenesis of skin diseases.
- To highlight the connection between acquired environmental factors and DNA methylation in skin conditions.
Main Methods:
- Literature review of recent studies on DNA methylation and skin diseases.
- Analysis of the mechanisms by which environmental factors influence DNA methylation in skin.
Main Results:
- DNA methylation is a common epigenetic mechanism affected by environmental and dietary factors.
- Aberrant DNA methylation is a significant feature in the pathogenesis of both skin tumors and autoimmune-related skin disorders.
Conclusions:
- DNA methylation is a critical epigenetic factor in the development and progression of skin diseases.
- Understanding DNA methylation's role offers potential therapeutic targets for dermatological conditions.

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.

02:30Genomic Imprinting and Inheritance
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.

01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.

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...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
