Non-Coding RNAs and Their Role in Maintaining Epidermal Homeostasis.

In recent decades, there has been a significant amount of research on the biological role of non-coding RNAs (ncRNAs) in both normal and pathological conditions. Specifically, a growing body of evidence suggests that ncRNAs play a crucial role in maintaining epidermal homeostasis. These ncRNAs are involved in regulating epidermal differentiation and wound healing, as well as in pathological skin conditions, such as psoriasis and chronic wounds. The discovery of mechanisms such as RNA interference and other modes of action of ncRNAs has led to the development of novel therapeutic strategies, where ncRNAs could serve as targets, therapeutic agents, or diagnostic markers. This review explores the role of different classes of ncRNAs in the epidermis under normal and abnormal conditions, the mechanisms by which ncRNAs interact with other modulators of epidermal homeostasis, and the current state of ncRNA-based therapy.
