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 Metabolism of androgens by isolated human hair follicles
Beard hair follicles convert testosterone to 5α-dihydrotestosterone most intensively.
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 The biochemical and phenotypic characterization of females homozygous for 5 alpha-reductase-2 deficiency.
Females with 5 alpha-reductase-2 deficiency have less body hair, no acne, normal fertility, and delayed menarche.
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 Synthesis and biological evaluation of esters of 16-formyl-17-methoxy-dehydroepiandrosterone derivatives as inhibitors of 5α-reductase type 2
Certain derivatives are more effective 5α-reductase type 2 inhibitors than finasteride.
research Synthesis of 11α-hydroxyprogesterone hartens
Researchers successfully made new compounds for hormone level tests, but one attempt led to an unexpected product, correcting a past error.
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 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 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 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 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 Screening for 21-hydroxylase–deficient nonclassic adrenal hyperplasia among hyperandrogenic women: a prospective study
Testing basal 17-HP levels is a good way to screen for nonclassic adrenal hyperplasia in women with high androgen levels.
research LC-MS/MS improves screening towards 21-hydroxylase deficiency
LC-MS/MS is more reliable than immunoassays for diagnosing 21-hydroxylase deficiency.
research 258 11β-hydroxysteroid dehydrogenase type 1 inhibition attenuates the adverse effects of glucocorticoids on dermal papilla cells
Blocking a specific enzyme can reduce the negative impact of stress hormones on hair growth cells.
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 9 Role of 5α-reductase in health and disease
5α-reductase is essential for male sexual development and its inhibitors have potential in treating various conditions related to hormone action.
research Markers of peripheral androgen action in vivo and in vitro
Dihydrotestosterone (DHT) is crucial for conditions like male-pattern baldness and acne, and measuring a byproduct, androstanediol glucuronide, is a better way to assess DHT's effects than DHT blood levels.
research 6 Peripheral androgens and the role of androstanediol glucuronide
Androstanediol glucuronide is a reliable marker for hirsutism in women.
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 Characterization of a Partial cDNA for Lysyl Hydroxylase from Human Skin Fibroblasts; Lysyl Hydroxylase mRNAs Are Regulated Differently by Minoxidil Derivatives and Hydralazine
Minoxidil decreases LH expression, while hydralazine has mixed effects on prolyl and lysyl hydroxylase activities.
research Clinical biochemistry of dihydrotestosterone
