Shorter GGN repeats in the androgen receptor gene are linked to androgenetic alopecia.
research Increased androgen receptor messenger RNA in frontal-parietal hair follicles of women with androgenetic alopecia
Women with hair loss have more androgen receptors in certain hair follicles.
research Androgen receptor transactivity is potentiated by TGF-β1 through Smad3 but checked by its coactivator Hic-5/ARA55 in balding dermal papilla cells
TGF-β1 increases androgen receptor activity in hair loss, but Hic-5/ARA55 can counter this effect.
research Design, Synthesis, and Biological Characterization of Metabolically Stable Selective Androgen Receptor Modulators
Researchers developed new compounds that target the androgen receptor effectively with fewer side effects.
research Overexpression of Hedgehog Signaling Is Associated with Epidermal Tumor Formation in Vitamin D Receptor–Null Mice
Lack of vitamin D receptor increases skin tumor risk by boosting hedgehog signaling.
research 743 Adipocyte stem cells are maintained by Pdgfα signaling in the skin
Pdgfα signaling helps maintain fat cells in the skin and is important for hair growth, wound healing, and fighting infections.
research Insight into Recent Advances in Degrading Androgen Receptor for Castration-Resistant Prostate Cancer
New treatments targeting androgen receptors show promise for drug-resistant prostate cancer.
research Expression and Distribution of the Guanine Nucleotide-binding Protein Subunit Alpha-s in Mice Skin Tissues and Its Association with White and Black Coat Colors
The protein Gnαs is found more in black mice than white mice and may influence their coat color.
research Impact of One-Week Administration of Dihydrotestosterone in Rat Anterior Pituitary Gland
Dihydrotestosterone changes some hormone-related gene expressions in rat pituitary glands but doesn't affect the estrous cycle.
research Receptor activator of NF-κB (RANK) stimulates the proliferation of epithelial cells of the epidermo-pilosebaceous unit
RANK-RANKL signaling is essential for hair growth and skin health.
research Gender Specificity of a Genetic Variant of Androgen Receptor and Risk of Coronary Artery Disease
A genetic variant in the androgen receptor gene increases heart disease risk in women but not in men.
research Roles of p38- and c-jun NH2-terminal kinase-mediated pathways in 2-methoxyestradiol-induced p53 induction and apoptosis
2-Methoxyestradiol causes cancer cell death by activating specific pathways, but androgens can block this effect.
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 The Effect of Perinatal Blockade of Androgen Receptors on the Expression of Hypothalamic Estrogen Receptor‐a and Sexual Motivation in Male Rats
Blocking androgen receptors early in life increases estrogen levels and reduces sexual motivation in male rats.
research Thyroid Hormone Receptor Agonist Promotes Hair Growth in Mice
TDM10842, a thyroid hormone receptor activator, was found to effectively promote hair growth in mice.
research 412 High amphiregulin expression is a high-risk feature of acute graft-versus-host disease of the skin
High amphiregulin in the skin is a bad sign for acute graft-versus-host disease.
research An estrogen receptor pathway regulates the telogen-anagen hair follicle transition and influences epidermal cell proliferation.
Estrogen affects hair growth and skin cell multiplication.
research Analysis of androgen receptor expression and activity in the mouse brain
Androgen receptors in the mouse brain may explain cognitive and mood changes in prostate cancer treatment.
research Amphiregulin in Fibrotic Diseases and Cancer
Targeting amphiregulin may improve treatment for fibrosis and cancer.
research Effect of thioredoxin reductase 1 on glucocorticoid receptor activity in human outer root sheath cells
Thioredoxin reductase 1 does not affect glucocorticoid receptor activity in hair follicle cells.
research 569 Hypoxic response of the expression of TGF-β2 and BMP4 in human dermal papilla cells
Low oxygen levels affect the behavior of certain proteins in human skin cells.
research Cortisol Enhances the Expression of mac25/Insulin-Like Growth Factor-Binding Protein-Related Protein-1 in Cultured Osteoblasts**This work was supported by NIDDK Grant DK-45227 and a scholarship (to R.C.P.) from Fundacao Coordenacao de Aperfeicoa mento de Pessoal de Nivel Superior (CAPES), Universidade de Sao Paulo (Sao Paulo, Brazil).
