Summary
Epigenetic modifications like histone and m6A changes are vital for skin development and aging. Significant UV exposure alters skin
Area of Science:
- Dermatology and Epigenetics
- Molecular Biology of Skin
Background:
- Epigenetic regulation influences skin development, aging, and response to UV radiation.
- Limited understanding exists regarding epigenetic changes in neonatal skin development, aging, and UV response.
Purpose of the Study:
- To investigate epigenetic modifications (histone, genetic imprinting, m6A) during human skin development and aging.
- To analyze the impact of ultraviolet (UV) radiation on the skin's epigenetic landscape.
Main Methods:
- Transcriptome analysis of human skin samples from various ages and UV exposure levels.
- Utilized R software (version 4.0.3) for data analysis.
Main Results:
- Significant epigenetic changes observed during neonatal to adult skin development, impacting collagen, ECM, immunity, and keratinization.
- UV exposure at the minimal erythema dose altered multiple epigenetic effectors involved in ECM organization, immunity, and cellular processes.
- Epigenetic alterations due to UV were more pronounced in elderly skin compared to younger skin.
Conclusions:
- Histone modifications, genetic imprinting, and m6A modification are crucial for skin development.
- High-dose UV exposure significantly alters the expression of numerous epigenetic effectors in the skin.

Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

01:12Renewal of Skin Epidermal Stem Cells
2.4K
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...

01:14Changes in Skin Color: Clinical Perspectives
1.6K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

01:19Clinical Applications of Epidermal Stem Cells
2.7K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

03:17Inheritance of Chromatin Structures
6.2K
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying...
