research The role of androgen therapy
Androgens, male hormones, play a role in both men and women's health, and testosterone therapy can help women with low levels, but it's not suitable for pregnant or lactating women, or those with certain conditions.
research Genotype–Phenotype Correlation in Children With Congenital Adrenal Hyperplasia due to 21‐Hydroxylase Deficiency Using Next Generation Sequencing
Severe genetic variants in children with a specific adrenal condition match predicted symptoms well, but milder variants do not.
research Non-classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency revisited: an update with a special focus on adolescent and adult women
The update highlights that non-classic congenital adrenal hyperplasia is common in women with excess male hormones, requires specific hormone tests for diagnosis, and has various treatment options depending on age and symptoms.
research Generation of comparative pharmacophoric model for steroidal 5α-reductase I and II inhibitors: A 3D-QSAR study on 6-azasteroids
The study created a model to help design new inhibitors for steroidal 5α-reductase enzymes.
research HSD3B1 Genotypes Conferring Adrenal-Restrictive and Adrenal-Permissive Phenotypes in Prostate Cancer and Beyond
Certain HSD3B1 gene types are linked to worse prostate cancer outcomes and affect treatment response and other health conditions.
research Epitestosterone—an endogenous antiandrogen?
Epitestosterone may act as a weak antiandrogen and can inhibit an enzyme involved in testosterone metabolism.
research Maternal androgen excess inhibits fetal cardiomyocytes proliferation through RB-mediated cell cycle arrest and induces cardiac hypertrophy in adulthood
Excess maternal androgens can cause heart problems in offspring.
research The expression of inducible nitric oxide synthase (iNOS) in the testis and epididymis of rats with a dihydrotestosterone (DHT) deficiency
DHT deficiency increases iNOS expression in rat testis and epididymis.
research Synthesis and 5α-Reductase Inhibitory Activity of C21 Steroids Having 1,4-diene or 4,6-diene 20-ones and 4-Azasteroid 20-Oximes
Three specific 4-azasteroid-2-oximes showed strong enzyme inhibition, but less than finasteride.
research Editorial: Androgen-dependent diseases and their treatment
Continued research and awareness are needed to improve treatments for androgen-dependent diseases.
research 4 Vitamin D resistance
Some people have genetic mutations that make them resistant to vitamin D, leading to rickets even with enough vitamin D intake.
research Inflammation dynamically regulates steroid hormone metabolism and action within macrophages in rheumatoid arthritis
Inflammation in rheumatoid arthritis increases steroid activation in cells, reducing inflammation.
research Selenoproteins Are Essential for Proper Keratinocyte Function and Skin Development
Selenoproteins are crucial for healthy skin and hair.
research Genetics and Epigenetics of Polycystic Ovary Syndrome
Genes and epigenetic changes are important in the development of Polycystic Ovary Syndrome.
research Inhibition of 5α-Reductase Activity in SZ95 Sebocytes and HaCaT Keratinocytes In Vitro
The substance MK386 effectively blocked testosterone conversion and reduced cell growth in certain skin cells, but inhibiting 5α-reductase alone may not greatly improve acne.
research Relationship Between Steroid Hormones and Metabolic Profile in Women With Polycystic Ovary Syndrome
Overweight women with PCOS have higher levels of certain hormones that could indicate a higher risk of heart and metabolic problems.
research Receiver operating characteristic analysis of the performance of basal serum hormone profiles for the diagnosis of polycystic ovary syndrome in epidemiological studies
Low SHBG and high FAI, FT, and DHEAS levels are effective in identifying PCOS.
research Rare steroid cell tumor found in region North Brazil: case report
A rare ovarian tumor was diagnosed in a woman from North Brazil, and surgery is the preferred treatment.
research 9209 Functional Evaluation Of Novel CYP21A2 Variants: Expanding The Genetic Basis Of Non-classic CAH
Certain genetic variants impair enzyme activity, contributing to non-classic congenital adrenal hyperplasia.
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 HORMONAL STATUS IN POSTMENOPAUSAL ANDROGENETIC ALOPECIA
No significant hormone differences found in postmenopausal women with androgenetic alopecia.
research Steroid induced central serous retinopathy following follicular unit extraction in androgenic alopecia
Steroid use can cause a rare eye condition called central serous retinopathy, which can lead to permanent vision damage.
research Nongenomic effects of 1α,25-dihydroxyvitamin D 3 on cartilage formation deduced from comparisons between Cyp27b1 and Vdr knockout mice
1α,25-dihydroxyvitamin D3 directly affects cartilage growth and development.
research 11-Oxyandrogens in Adolescents With Polycystic Ovary Syndrome
Girls with PCOS have higher levels of certain androgens, which are linked to excess hair growth, but these androgens don't help diagnose PCOS.
research Ectoderm-Targeted Overexpression of the Glucocorticoid Receptor Induces Hypohidrotic Ectodermal Dysplasia
Overexpression of the glucocorticoid receptor in mice causes developmental defects similar to ectodermal dysplasia.
research Age‐dependent regulation by androgens of gene expression in the anterior hypothalamus and stress‐induced release of adrenal hormones in adolescent and adult male rats
