research Preparation of3H-labelled testosterone metabolites
The conclusion is that tritium-labeled testosterone metabolites can be made and are better converted into dihydrotestosterone in skin cells than in prostate tissue.
research Binding of Steroid Hormones by the 105,000 x g Supernatant Fraction from Homogenates of Rat Skin and Variations during the Hair Cycle
Steroid hormone binding in rat skin varies with pH, heat, and hair cycle phases.
research Testosterone protects female embryonic heart H9c2 cells against severe metabolic stress by activating estrogen receptors and up-regulating IES SUR2B
Testosterone protects female heart cells from stress by activating estrogen receptors.
research Urinary steroids in men with male-pattern alopecia
Men with male-pattern baldness have higher levels of certain testosterone metabolites and may have more active androgen metabolism.
research Dihydrotestosterone, Active Androgen Metabolites and Related Pathology
Dihydrotestosterone (DHT) and its active metabolites play a key role in various diseases, and the development of 5α-reductase inhibitors can help treat these conditions.
research Mechanism of action of androgen in hair follicles
Testosterone affects hair follicles differently across body sites, with beard hair follicles showing more activity of a specific enzyme and presence of androgen receptors compared to scalp hair.
research Synthesis and in Vitro Evaluation of 4-Substituted N-(1,1-Dimethylethyl)-3-oxo-4-androstene-17.beta.-carboxamides as 5.alpha.-Reductase Inhibitors and Antiandrogens
The new compounds moderately block a specific enzyme and strongly counteract a male hormone, suggesting potential for treating certain male-related health conditions.
research Serum androgen bioactivity is low in children with premature adrenarche
research Urinary steroid metabolome shows adrenal, gonadal, and neuroactive steroid dysregulation in adolescents with depression
Depressed teens have different steroid levels in urine, which may help identify and treat them.
research Plasma androsterone/epiandrosterone sulfates as markers of 5α-reductase activity: Effect of finasteride in normal men
Finasteride effectively lowers specific hormone levels, helping monitor treatment progress.
research Structural basis for the catalysis and inhibition of human steroid 5α‐reductase 2
The research gives new understanding on how human steroid 5α-reductases work and how drugs like finasteride inhibit them, which could help in creating new drugs.
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 Megestrol Acetate Increases the Proliferation, Migration, and Adipogenic Differentiation of Adipose-Derived Stem Cells via Glucocorticoid Receptor
Megestrol acetate helps fat-derived stem cells grow, move, and turn into fat cells through a specific receptor.
research Gene Expression Analysis Reveals Novel Functions of Vitamin D and Glucocorticoids
Vitamin D and glucocorticoids affect bone growth, metabolism, and immune response.
research Antihormonal properties of some new A-homo-B, 19-dinor steroids of the androstane series
New A-homo-B, 19-dinor steroids showed strong antiandrogenic activity without affecting the enzyme 5α-reductase or androgen receptor binding.
research Synthesis, antiproliferative activity, acute toxicity and assessment of the antiandrogenic activities of new androstane derivatives
research Gas chromatography/mass spectrometry based hair steroid profiling may reveal pathogenesis in hair follicles of the scalp
Analyzing hair with this method can help understand and monitor scalp conditions and treatment effects.
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 Isotope Dilution-Based Targeted and Nontargeted Carbonyl Neurosteroid/Steroid Profiling
Researchers created a new method to measure brain steroids, finding higher levels of certain steroids and changes due to a drug.
research Dehydroepiandrosterone- and glucose-6-phosphate-dehydrogenases in the hair cycle of the rat
research Synthesis and Pharmacological Evaluation of New 16-Methyl Pregnane Derivatives.
New pregnane derivatives were more effective than finasteride at inhibiting a key enzyme for male pattern baldness.
research EFFECTS OF STEROID HORMONES ON DEVELOPING MOUSE SKIN IN VITRO
Cortisol and corticosterone thin mouse skin and regress hair follicles, while testosterone promotes skin and hair development.
research 5α-reductase activity in women with polycystic ovary syndrome: a systematic review and meta-analysis
Women with PCOS have higher 5α-reductase activity, which may be linked to insulin resistance.
research The Function of 5α-reductase in Related Diseases
5α-reductase enzyme affects hormone levels, influencing conditions like acne and hair loss.
research Studies on neurosteroids XXIV. Determination of neuroactive androgens, androsterone and 5α‐androstane‐3α,17β‐diol, in rat brain and serum using liquid chromatography–tandem mass spectrometry
The methods accurately measured brain androgens, showing most 5α-androstane-3α,17β-diol comes from outside the brain, while androsterone is both transported and made in the brain.
research [Skin cells as steroid target; the steroid action in some skin diseases and wound healing].
Steroids affect skin health and healing, offering new treatment options.
research OR09-5 Importance of Islet Intracrinology for Glucose-Stimulated Insulin Secretion (GSIS) in the Male
Androgens and estrogens are crucial for insulin secretion in males.
research Determination of steroid hormones in human hair as a retrospective biomarker with HPLC-MS/MS
A new method accurately measures long-term hormone levels in hair.
