Type 2 5α-reductase plays a key role in hair loss.
research Synthesis of novel andostane-N-cyclohexyl-17-carboxamides, and their effect on the 5α-reductase isoform 2, the androgen receptor, and androgen-dependent glands
New compounds were made and tested, with compound 6 showing potential for treating prostate-related diseases.
research 244 Defective maintenance of hair follicle stem cells through COL17A1 loss orchestrates the hair follicle aging program
Loss of COL17A1 causes hair follicle stem cells to age and leads to hair loss.
research ADAM17 variant causes hair loss via ubiquitin ligase TRIM47 mediated degradation
A variant in the ADAM17 gene causes hair loss by increasing protein degradation through TRIM47.
research 24-Hydroxycholesterol suppresses steroid 5α-reductase-catalyzed conversion in human glioblastoma cell lines: A novel link between brain cholesterol homeostasis and androgen metabolism
24-Hydroxycholesterol reduces DHT formation in brain cancer cells, linking cholesterol and hormone metabolism.
research SAT-210 When Acne, Hirsutism and Menstrual Irregularities Are More Than PCOS
Non-classic congenital adrenal hyperplasia (NCCAH) can mimic PCOS and requires genetic testing for proper diagnosis and treatment.
research Luteinizing Hormone and Human Chorionic Gonadotropin Decrease Type 2 5α-Reductase and Androgen Receptor Protein Levels in Women’s Skin
LH and hCG reduce certain protein levels in women's skin.
research Determination Method for Steroid 5α-Reductase Activity Using Liquid Chromatography/Atmospheric Pressure Chemical Ionization–Mass Spectrometry
A new method was developed to measure and assess the activity and inhibition of the enzyme steroid 5α-reductase.
research Estimation of Serum Level of Omentin-1 In Hirsute Female: A Single Center Study
Females with idiopathic hirsutism have higher levels of omentin-1, which may lead to excessive hair growth.
research Dihydrotestosterone and 5α-Reductase
Dihydrotestosterone and 5α-Reductase play a role in hair loss and prostate health, and finasteride can increase hair growth in men without affecting sperm production, but it doesn't work for postmenopausal women with hair loss.
