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 Development of a Liquid Chromatography/Mass Spectrometry-Based Inhibition Assay for the Screening of Steroid 5-α Reductase in Human and Fish Cell Lines
A new method was created to test the effectiveness of Dihydrotestosterone (DHT) inhibitors, like finasteride and dutasteride, in human and fish cells. The results showed fish cells are more sensitive to these treatments, and dutasteride works better than finasteride in all tested cells.
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 Highly Sensitive Simultaneous Measurement of Steroid Hormone in Human Serum by Liquid Chromatography-electrospray Ionization Tandem Mass Spectrometry
A new method accurately measures nine steroid hormones in human serum with high sensitivity.
research Realising the therapeutic potential of neuroactive steroid modulators of the GABAA receptor
Neuroactive steroids show promise for treating mental and neurological disorders by targeting GABA_A receptors.
research Influence of sex and functional status on the value of serum steroid profiling in discriminating adrenocortical carcinoma from adrenocortical adenoma
Serum steroid profiling, especially 11-deoxycortisol, helps distinguish between adrenocortical carcinoma and adenoma, considering sex and functional status.
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 Metabolomic biomarkers in women with polycystic ovary syndrome: a pilot study
Certain metabolites are lower in women with PCOS and could be potential markers for the condition.
research UHPLC/Q-TOFMS-based plasma metabolomics of polycystic ovary syndrome patients with and without insulin resistance
The research found different metabolism changes in PCOS patients and suggested new potential markers for diagnosing PCOS with or without insulin resistance.
research Towards Best Practice in Hair Metabolomic Studies: Systematic Investigation on the Impact of Hair Length and Color
Hair color and length affect metabolite profiles in hair, so they should be considered in hair analysis.
research Measurement of steroid hormones by liquid chromatography-tandem mass spectrometry with small amounts of hair
A new method accurately measures steroid hormones in a few hair strands and could help study chronic stress and hair loss.
research Measurement of Steroid Hormones in Hair: an Analysis of Hormone Dynamics in Hair Follicles
The method accurately measures steroid hormones in hair to study hormone dynamics related to hair loss.
research Steroidogenesis in steroid related cancers
Steroid-producing capabilities in certain cancers may contribute to treatment resistance.
research Steroid Biomarkers and Genetic Studies Reveal Inactivating Mutations in Hexose-6-Phosphate Dehydrogenase in Patients with Cortisone Reductase Deficiency
Certain mutations in the H6PD gene cause Cortisone Reductase Deficiency by affecting hormone production.
research Incidence of type 2 diabetes mellitus in men receiving steroid 5α-reductase inhibitors: population based cohort study
Men taking dutasteride or finasteride have a slightly higher risk of developing type 2 diabetes.
research Indirect clinical markers for the detection of anabolic steroid abuse beyond the conventional doping control in athletes
New signs like changes in blood markers, physical symptoms, and behavioral shifts may help detect hidden steroid use in athletes.
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 Intratumoral De Novo Steroid Synthesis Activates Androgen Receptor in Castration-Resistant Prostate Cancer and Is Upregulated by Treatment with CYP17A1 Inhibitors
Prostate cancer cells can make their own androgens to activate the androgen receptor, and treatments like abiraterone may increase this ability, suggesting new therapies should target the entire steroid-making pathway.
research Patients treated for male pattern hair with finasteride show, after discontinuation of the drug, altered levels of neuroactive steroids in cerebrospinal fluid and plasma
Finasteride affects brain and blood steroids, causing lasting sexual and emotional side effects.
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 plant hormones: Effects outside plant kingdom
Plant steroid hormones show growth, health, and medicinal benefits in various organisms, including potential for treating diseases.
research Anabolic-androgenic steroids and cardiovascular risk
Using steroids can increase the risk of heart problems.
research In Vivo Time-Dependent Inhibition of Human Steroid 5a-Reductase by Finasteride
Finasteride poorly inhibits type 1 5AR, affecting its effectiveness.
research Steroid sulfatase inhibitors
Steroid Sulfatase inhibitors show promise in treating hormone-dependent disorders like cancers, hair loss, and acne, with 667COUMATE being a potential candidate for breast cancer treatment trials.
research Retinoid-mediated stimulation of steroid sulfatase activity in myeloid leukemic cell lines requires RARα and RXR and involves the phosphoinositide 3-kinase and ERK-MAP kinase pathways
Retinoids increase steroid sulfatase activity in leukemia cells through RARα/RXR and involves certain pathways like phosphoinositide 3-kinase and ERK-MAP kinase.
