Expressing the human vitamin D receptor in skin cells prevents hair loss in certain mice.
research Evaluation of Keratinocyte Proliferation and Differentiation in Vitamin D Receptor Knockout Mice*
Alopecia in VDR knockout mice is due to a defect in hair cycle initiation, not keratinocyte issues.
research Thyroid-Stimulating Hormone, a Novel, Locally Produced Modulator of Human Epidermal Functions, Is Regulated by Thyrotropin-Releasing Hormone and Thyroid Hormones
The skin produces and responds to thyroid-stimulating hormone, which is controlled by other thyroid-related hormones.
research Cloning of a Functional Vitamin D Receptor from the Lamprey (Petromyzon marinus), an Ancient Vertebrate Lacking a Calcified Skeleton and Teeth
Lampreys have a functional vitamin D receptor that may help detoxify harmful substances.
research Androgenetic Alopecia

research Structure of human type II 5 alpha-reductase gene
The human type II 5α-reductase gene has a specific structure important for understanding certain medical conditions.
research Prolactin Signaling Influences the Timing Mechanism of the Hair Follicle: Analysis of Hair Growth Cycles in Prolactin Receptor Knockout Mice*
Prolactin affects when mice shed and grow hair.
research 17β-Estradiol and ICI-182780 regulate the hair follicle cycle in mice through an estrogen receptor-α pathway
Estradiol stops hair growth in mice, but an antagonist can reverse this effect.
research Hereditary 1,25-Dihydroxyvitamin D Resistant Rickets due to a Mutation Causing Multiple Defects in Vitamin D Receptor Function
A specific gene mutation causes vitamin D resistance, but certain vitamin D analogs might help.

research Change in Hair Color in Mice Induced by Injection of α-MSH
Injecting α-MSH made mice's hair turn black.
research Detection of Functionally Active Melanocortin Receptors and Evidence for an Immunoregulatory Activity of α-Melanocyte-Stimulating Hormone in Human Dermal Papilla Cells
αMSH may help regulate immune responses in hair follicles and its disruption could lead to hair loss.
research Ovarian Hypertension: Polycystic Ovary Syndrome
Polycystic Ovary Syndrome is linked to higher risk of hypertension and heart disease.
research Ligand-Dependent Actions of the Vitamin D Receptor Are Required for Activation of TGF-β Signaling during the Inflammatory Response to Cutaneous Injury
