hormones like testosterone bind to receptors, influencing gene expression
Androgen Receptor Signaling, also known as AR signaling, is a biological pathway where androgens (male hormones like testosterone) bind to androgen receptors in cells. This binding activates the receptors, which then influence the expression of specific genes, affecting various bodily functions such as hair growth, muscle development, and reproductive processes. In the context of hair, AR signaling can play a role in conditions like androgenetic alopecia (pattern hair loss).
