    GlossaryRetinoic Acid Signaling (retinoic acid pathway)

    regulates gene expression through vitamin A derivatives

    Retinoic Acid Signaling, also known as RA signaling, is a biological pathway where retinoic acid, a derivative of vitamin A, binds to specific receptors in cells to regulate gene expression. This pathway is crucial for various physiological processes, including cell growth, differentiation, and embryonic development. In the context of hair biology, RA signaling can influence hair follicle development and cycling, potentially impacting conditions like alopecia.
