small RNA molecule regulating gene expression and hair follicle development
miR-31 is a type of microRNA, which are small, non-coding RNA molecules that play a role in regulating gene expression. Specifically, miR-31 has been found to influence various biological processes, including cell growth, differentiation, and apoptosis. In the context of hair and alopecia, miR-31 can affect hair follicle development and cycling, potentially contributing to hair loss conditions.
