960-990 / 1000+ results research Cellular actions of testosterone in vascular cells: Mechanism independent of aromatization to estradiol
Testosterone affects vascular cells directly without converting to estradiol.
research Increased frequency of heterozygoshy for the 21 hydroxylase deficiency among hersute females
Women with excessive hair growth or polycystic ovary disease may more often carry a gene variant for 21 hydroxylase deficiency.
research Relationship between plasma sex hormones and severity of coronary artery disease
Lower testosterone levels in men may be linked to a higher risk of severe coronary artery disease.
research Azasteroids as inhibitors of testosterone 5α-reductase in mammalian skin
Certain 4-azasteroids are effective at blocking the enzyme that processes testosterone in human skin and could help treat acne, excessive hair growth, and male pattern baldness.
research Characteristics of flutamide action on prostatic and testicular functions in the rat
Flutamide combined with an LHRH agonist effectively inhibits prostate growth, suggesting it could treat prostate cancer.
research Molecular interactions of progesterone derivatives with 5α-reductase types 1 and 2 and androgen receptors
Certain progesterone derivatives can inhibit enzymes and reduce androgenic activity, potentially affecting prostate growth.
research The efficacy of an adjuvant norethisterone (jenapharm) therapy in endometrial cancer
Norethisterone (jenapharm) therapy is effective for endometrial cancer.
research A comparative study of Aldactone® and Diane® in the treatment of hirsutism
Aldactone was more effective in reducing hair growth in women with hirsutism than Diane, despite having less impact on hormone levels.
research Invalidation of a commercially available human 5α-dihydrotestosterone immunoassay
The DHT immunoassay is unreliable due to high cross-reactivity with testosterone.
research The therapeutic use of androgens in women
Testosterone replacement may improve sexual desire and bone health in women with low androgen levels, but more research is needed on its long-term safety.
research Overexpression of aldo-keto reductase 1C3 (AKR1C3) in LNCaP cells diverts androgen metabolism towards testosterone resulting in resistance to the 5α-reductase inhibitor finasteride
Too much AKR1C3 enzyme causes resistance to finasteride by increasing testosterone.
research Gene expression of type 2 17β hydroxysteroid dehydrogenase in scalp hairs of hirsute women
Hirsute women have lower type 2 17β-HSD enzyme levels, which improve with treatment.
research A high-performance liquid chromatography–tandem mass spectrometry assay of the androgenic neurosteroid 3α-androstanediol (5α-androstane-3α,17β-diol) in plasma
Testosterone increases 3α-androstanediol levels, which can be blocked by finasteride.
research Metabolic study of androsta-1,4,6-triene-3,17-dione in horses using liquid chromatography/high resolution mass spectrometry
The study found that urine metabolites M1b or M4 are the best indicators of ATD use in horses, with detection possible up to 77 hours in urine and 28 hours in blood.
research Novel C-6 substituted and unsubstituted pregnane derivatives as 5α-reductase inhibitors and their effect on hamster flank organs diameter size
Certain compounds reduced hamster flank organ size by inhibiting 5α-reductase, like finasteride, without affecting androgen receptors.
research New ester derivatives of dehydroepiandrosterone as 5α-reductase inhibitors
New compounds may help treat prostate issues without affecting androgen receptors.
research Quantitative analysis of 34 sex (pro)hormones, conjugates and bioactive oxidation products thereof in human plasma by GC- and LC-MS/MS and systematic investigation of overestimations of analyte concentrations not accounted for by method validation
The method accurately measures sex hormones in human plasma but can have small errors.
research Progesterone-induced stimulation of mammary tumorigenesis is due to the progesterone metabolite, 5α-dihydroprogesterone (5αP) and can be suppressed by the 5α-reductase inhibitor, finasteride
Progesterone byproduct 5αP stimulates mammary tumor growth, but finasteride can suppress it.
research Role of 5α-dihydrotestosterone in testicular development of gilthead seabream following finasteride administration
DHT affects testicular development and regulates spermatogenesis in some fish.
research RU 58841, a new specific topical antiandrogen: A candidate of choice for the treatment of acne, androgenetic alopecia and hirsutism
RU 58841 may treat acne, hair loss, and excessive hair growth.
research PNU 157706, a novel dual type I and II5α-reductase inhibitor
PNU 157706 is a more effective treatment than finasteride for conditions caused by DHT, like enlarged prostate and hair loss.
research Cloning, expression and characterization of rhesus macaque types 1 and 2 5alpha-Reductase: evidence for mechanism-Based inhibition by finasteride
Finasteride inhibits enzyme activity in rhesus macaques, suggesting they're useful for evaluating similar drugs.
research FCE 28260, a new 5α-reductase inhibitor: In vitro and in vivo effects
FCE 28260 is a stronger and longer-lasting inhibitor of 5α-reductase than finasteride, which may make it a better treatment for certain medical conditions.
research Expression of 11β-hydroxysteroid dehydrogenase type 1 in visceral and subcutaneous adipose tissues of patients with polycystic ovary syndrome is associated with adiposity
Increased HSD11B1 enzyme expression is linked to higher body fat and insulin resistance.
