Summary
MicroRNAs (miRNAs) are key regulators of gene expression in mammalian skin development and disease. This review summarizes recent advances in understanding miRNA functions in skin morphogenesis, differentiation, and cancer.
Area of Science:
- Dermatology
- Molecular Biology
- Gene Regulation
Background:
- Mammalian skin, the largest organ, requires precise gene expression for development and maintenance.
- MicroRNAs (miRNAs) represent a novel regulatory layer influencing skin biology.
- The skin's accessibility and genetic tractability make it an excellent model for studying miRNA functions.
Purpose of the Study:
- To review the current understanding of miRNA roles in mammalian skin.
- To highlight recent findings on miRNA expression patterns and functions.
- To discuss the implications of miRNAs in skin development, homeostasis, and disease.
Main Methods:
- Literature review of studies on miRNAs in mammalian skin.
- Analysis of gene expression patterns and functional roles of miRNAs.
- Examination of miRNA involvement in skin morphogenesis, differentiation, and diseases like cancer.
Main Results:
- Significant progress has been made in identifying miRNA expression profiles in skin.
- miRNAs are crucial for embryonic skin development and adult skin homeostasis.
- Dysregulated miRNA expression is implicated in various skin conditions, including cancer.
Conclusions:
- miRNAs play critical roles in mammalian skin biology.
- Further research is needed to fully elucidate miRNA functions and therapeutic potential in skin diseases.
- Understanding miRNA regulatory networks is essential for advancing dermatology.

01:27The Skin Microbiota
The human skin serves as a complex ecosystem inhabited by a diverse community of microorganisms, including bacteria, fungi, and viruses. This microbiome plays a critical role in maintaining skin health and defending against pathogenic invaders. The composition of microbial communities varies significantly across different regions of the body, influenced primarily by the local levels of moisture and sebum.Regional Variation in Skin MicrobiotaCutibacterium acnes predominantly colonizes sebaceous...
01:22MicroRNAs
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA ends...

01:12Renewal of Skin Epidermal Stem Cells
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 cells,...
01:23Role of Skin in Vitamin D Synthesis
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).
