Genetic variations greatly affect individual metabolism and can impact health and disease risk.
research C19and C215β/5αMetabolite Ratios in Subjects Treated with the 5α-Reductase Inhibitor Finasteride: Comparison of Male Pseudohermaphrodites with Inherited 5α-Reductase Deficiency*
Finasteride may treat baldness but less effective for those with 5α-reductase deficiency.
research Is the metabolism of testosterone to 5α-dihydrotestosterone required for androgen action in the skin?
Testosterone conversion to 5α-DHT may not be essential for its effects on the skin.
research 6 Peripheral androgens and the role of androstanediol glucuronide
Androstanediol glucuronide is a reliable marker for hirsutism in women.
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 Preliminary pharmacokinetics and metabolism of novel non-steroidal antiandrogens in the rat: Relation of their systemic activity to the formation of a common metabolite
Two non-steroidal antiandrogens, RU 58841 and RU 56187, form a common metabolite at different rates, which may influence their effects; RU 56187 could be used for prostate cancer treatment and RU 58841 for acne treatment.
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 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 Gonadal Sex Steroids: Production, Action and Interactions in Mammals
The document concludes that sex hormones are crucial for mammalian reproduction, health, and behavior, and require more research for therapeutic use.
research Early postnatal neuroactive steroid manipulation differentially affects recognition memory and passive avoidance performance in male rats
Changing neuroactive steroids in baby male rats affects their memory and learning differently as they grow up.
research Urinary steroids in women with androgenic alopecia
Women with hair loss had higher levels of certain hormones, suggesting a link to a condition like PCOS.
research Finasteride, A Steroid 5α-Reductase Inhibitor, Does Not Affect the Oxidative Metabolism of Antipyrine
Finasteride doesn't affect antipyrine metabolism, so interactions with cytochrome P-450 enzyme drugs are unlikely.
research Relative binding affinity of novel steroids to androgen receptors in hamster prostate
New steroids were effective in blocking male hormone receptors in hamster prostates.
research Neuroactive Steroids and Ethanol Exposure: Relevance to Ethanol Sensitivity and Alcohol Use Disorders Risk
Neuroactive steroids may affect the risk and treatment of alcohol use disorders.
research Adrenal steroid precursors exert potent androgenic action in the hamster sebaceous glands of flank organs and ears.
Certain adrenal hormones can strongly stimulate oil gland growth in hamster skin, similar to male hormones.
research Neuroactive steroid levels and psychiatric and andrological features in post-finasteride patients
Post-finasteride patients show changed neuroactive steroid levels, possibly causing erectile dysfunction and depression.
research Steroid Sulfatase: Molecular Biology, Regulation, and Inhibition
The enzyme steroid sulfatase is linked to breast cancer and other conditions, and inhibitors are being developed for treatment.
research 5α-Reductase inhibitors alter steroid metabolism and may contribute to insulin resistance, diabetes, metabolic syndrome and vascular disease: a medical hypothesis
Some hair loss and prostate drugs might increase the risk of diabetes and heart disease.
research Rat steroid 5α-reductase kinetic characteristics: Extreme pH-dependency of the type II isozyme in prostate and epididymis homogenates
The activity of a specific rat enzyme in the prostate and epididymis is highly dependent on the acidity level.
research Molecular interactions of natural and synthetic steroids in female hamsters’ flank organs
Testosterone, progesterone, and levonorgestrel change enzyme levels related to fat production in hamster skin, which could affect skin oil and acne.
research Crystal structure of steroid reductase SRD5A reveals conserved steroid reduction mechanism
The structure of SRD5A reveals how it reduces steroids, aiding drug design for related health conditions.
research STEROIDS AND STEROID-LIKE COMPOUNDS
Athletes use steroids to enhance performance despite health risks and legal issues, and education on their dangers is needed.
research Steroid 5α-reductase 2 deficiency leads to reduced dominance-related and impulse-control behaviors
Mice lacking steroid 5α-reductase 2 show less aggression and better impulse control.
