research Expression of mRNA for androgen receptor, 5alpha-reductase and 17beta-hydroxysteroid dehydrogenase in human dermal papilla cells
Hair sensitivity to androgens is partly controlled by specific enzyme expressions in different hair areas.
research The enzyme and inhibitors of 4-ene-3-oxosteroid 5α-oxidoreductase
Inhibitors of the enzyme 5 alpha-reductase could potentially treat disorders like prostate cancer and baldness.
research The diagnosis of nonclassic congenital adrenal hyperplasia due to 21-hydroxylase deficiency, based on serum basal or post-ACTH stimulation 17-hydroxyprogesterone, can lead to false-positive diagnosis
Using 17-hydroxyprogesterone levels to diagnose nonclassic congenital adrenal hyperplasia can result in many incorrect diagnoses.
research Localization, Age- and Site-Dependent Expression, and Regulation of 11β-Hydroxysteroid Dehydrogenase Type 1 in Skin
Increased 11β-HSD1 activity in skin may contribute to aging and could be targeted to reduce aging effects.
research 17α‐estradiol induces aromatase activity in intact human anagen hair follicles ex vivo
17α-estradiol boosts aromatase activity in female hair follicles, potentially helping with hair loss.
research LC-MS/MS improves screening towards 21-hydroxylase deficiency
LC-MS/MS is more reliable than immunoassays for diagnosing 21-hydroxylase deficiency.
research Oxidative Activity of the Type 2 Isozyme of 17β-Hydroxysteroid Dehydrogenase (17β-HSD) Predominates in Human Sebaceous Glands
The enzyme 17β-HSD type 2 mainly performs oxidation in human sebaceous glands, which may help protect against acne.
research Disruption of androgen metabolism, regulation and effects : involvement of steroidogenic enzymes
Anabolic steroids and inflammation can disrupt androgen metabolism, potentially causing health issues.
research Dihydrotestosterone Stimulates 5a-Reductase Activity in Pubic Skin Fibroblasts*
Dihydrotestosterone increases the activity of an enzyme in pubic skin cells that converts testosterone to dihydrotestosterone.
research Ovarian intratumoral 21-hydroxylase deficiency in a postmenopausal hirsute woman
A postmenopausal woman's masculine symptoms improved after surgery for a hormone-producing ovarian tumor.
research Predominant expression of 5 alpha-reductase type 1 in pubic skin from normal subjects and hirsute patients.
The main enzyme found in pubic skin that could be targeted to treat excessive hair growth is 5 alpha-R2.
research Bound on the Risk for M-SVMs
The enzyme system in hair follicles is similar to the liver's and is inhibited by certain substances.
research Vitamin D-dependent rickets type II. Defective induction of 25-hydroxyvitamin D3-24-hydroxylase by 1,25-dihydroxyvitamin D3 in cultured skin fibroblasts.
Measuring 24-OHase induction helps identify defects in vitamin D processing and predict treatment response.
research Hair Cycle-Specific Immunolocalization of Retinoic Acid Synthesizing Enzymes Aldh1a2 and Aldh1a3 Indicate Complex Regulation
The enzymes Aldh1a2 and Aldh1a3 are involved in making retinoic acid in hair follicles and have different roles in hair growth.
research Activity of type 1 5α-reductase is greater in the follicular infrainfundibulum compared with the epidermis
The enzyme type 1 5α-reductase is more active in the hair follicle's lower part than in the skin's outer layer.
research More about X‐linked testicular feminization of the mouse as a noninducible (is) mutation of a regulatory locus: 5α‐androstan‐3α‐17ß‐diol as the true inducer of kidney alcohol dehydrogenase and ß‐glucuronidase
A specific metabolite, not a receptor protein, triggers the production of certain kidney enzymes, but this process is disrupted in mice with a mutation causing testicular feminization.
research Functional characterization and unraveling the structural determinants of novel steroid hydroxylase CYP154C7 from Streptomyces sp. PAMC26508
CYP154C7 enzyme can effectively modify steroids and is promising for commercial use.
research Dehydroepiandrosterone- and glucose-6-phosphate-dehydrogenases in the hair cycle of the rat
research 6 Peripheral androgens and the role of androstanediol glucuronide
Androstanediol glucuronide is a reliable marker for hirsutism in women.
research Isotretinoin-unresponsive acne as a sign of a congenital disorder: a case of 21-hydroxylase deficiency
Acne not improved by usual treatments may indicate a genetic disorder.
research Clinical biochemistry of dihydrotestosterone
Understanding how DHT works is important for diagnosing and treating hormone-related disorders.
research Scalp hair 17‐hydroxyprogesterone and androstenedione as a long‐term therapy monitoring tool in congenital adrenal hyperplasia
Scalp hair 17-OHP and androstenedione levels can help monitor treatment in CAH patients.
research Characterization of response of murine hair follicle-derived keratinocyte against androgen and testosterone 5α-redactase activity
Mouse hair cells respond to male hormones by growing less, and this can be stopped by certain blockers.
research Androgen Regulation of the Human Hair Follicle: The Type I Hair Keratin hHa7 Is a Direct Target Gene in Trichocytes
The hHa7 gene is regulated by androgens in certain body hair, not scalp hair.
