research Sex differences in COVID-19: the role of androgens in disease severity and progression
Male hormones like testosterone may make COVID-19 worse, and testing for sensitivity to these hormones could help predict how severe a patient's symptoms might be. Treatments that reduce these hormones are being explored.
research Significance of the polyglutamine tract polymorphism in the androgen receptor
The length of the CAG repeat in the androgen receptor gene affects the risk and progression of prostate cancer, BPH, infertility, and undermasculinized genitalia.
research Androgen receptor gene CAG repeat polymorphism in women with polycystic ovary syndrome
Longer CAG repeat lengths in the androgen receptor gene are linked to higher testosterone levels in women with PCOS.
research Androgens Affect the Activity of Human Sebocytes in Culture in a Manner Dependent on the Localization of the Sebaceous Glands and Their Effect Is Antagonized by Spironolactone
Male hormones affect oil-producing skin cells differently based on their body location, and the drug spironolactone can reduce these effects.
research 7 Regulation of androgen receptor and 5α-reductase in the skin of normal and hirsute women
The exact cause of increased 5α-reductase activity leading to hirsutism in women is still unknown.
research CAG Repeat Testing of Androgen Receptor Polymorphism: Is This Necessary for the Best Clinical Management of Hypogonadism?
Testing for CAG repeat polymorphism in the androgen receptor gene is not currently recommended for managing hypogonadism.
research Postscreening follow-up of the Finnish Prostate Cancer Screening Trial on putative prostate cancer risk factors: vitamin and mineral use, male pattern baldness, pubertal development and non-steroidal anti-inflammatory drug use
Late puberty may slightly lower prostate cancer risk, baldness is not linked to overall risk but less so with aggressive types, ibuprofen use may increase risk, and vitamins show no effect on risk.
research The Molecular Basis of Androgen Insensitivity
Mutations in the androgen receptor gene cause Androgen Insensitivity Syndrome, affecting sexual development.
research Anti-Androgen Effects of Extracts and Compounds fromGanoderma lucidum
Ganoderma lucidum may help treat prostate cancer by blocking male hormones and slowing cancer cell growth.
research Synthesis and structure–activity studies of side-chain derivatized arylhydantoins for investigation as androgen receptor radioligands
The nature of the side chain in RU 58841 derivatives greatly affects its AR affinity, with the N-(iodopropenyl) derivative 13 showing the highest AR binding affinity, suggesting its potential for developing high-affinity radioiodinated AR radioligands.
research Selected variants of the steroid-5-alpha-reductase isoforms SRD5A1 and SRD5A2 and the sex steroid hormone receptors ESR1, ESR2 and PGR: No association with female pattern hair loss identified
No link found between specific genes and female pattern hair loss.
research Synthesis and biological evaluation of amino-pyridines as androgen receptor antagonists for stimulating hair growth and reducing sebum production
A compound made by Pfizer can potentially stimulate hair growth and reduce oil production, making it a good candidate for topical use.
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 The direct inhibitory effect of dutasteride or finasteride on androgen receptor activity is cell line specific
Dutasteride and finasteride affect different cell types differently.
research Preparation of 4-aryl-2-trifluoromethylbenzonitrile derivatives as androgen receptor antagonists for topical suppression of sebum production
Scientists made a chemical (compound 4e) that can be applied on skin to reduce oil production, which can help with acne, but it might cause skin sensitivity to light.
research Pantolactams as androgen receptor antagonists for the topical suppression of sebum production
Pfizer found that pantolactam-based compounds can reduce sebum (skin oil) production when applied topically.
research Novel Missense Mutation in the P-Box of Androgen Receptor in a Patient with Androgen Insensitivity Syndrome
A new mutation linked to partial Androgen Insensitivity Syndrome and prostate cancer was found in a patient unhappy with their female gender assignment.
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 Development of radioiodinated nonsteroidal androgen receptor ligands for spect imaging of prostate cancer
Scientists at the University of Michigan Medical School successfully created a special compound that can be used to improve imaging of prostate cancer.
research Alterations in androgen conjugate levels in women and men with alopecia
Women with hair loss have higher androgen levels, while men with early balding have altered androgen ratios.
research Molecular genetics of androgen insensitivity
Mutations in the androgen receptor gene cause different levels of androgen insensitivity, making it hard to create simple tests for the condition.
research The anti-androgen combination, flutamide plus finasteride, paradoxically suppressed LH and androgen concentrations in pregnant spotted hyenas, but not in males
Flutamide and finasteride reduced sex hormones in pregnant hyenas, but increased them in males.
research Effect of Saw Palmetto Supplements on Androgen-Sensitive LNCaP Human Prostate Cancer Cell Number and Syrian Hamster Flank Organ Growth
Saw palmetto supplements may reduce prostate cancer cell growth without being toxic.
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 The Androgen Excess and PCOS Society criteria for the polycystic ovary syndrome: the complete task force report
The report concludes that PCOS is mainly a condition of excess male hormones and its definition may change as new information is discovered.
research Androgen Excess in Women: Experience with Over 1000 Consecutive Patients
Most women with excess male hormones have Polycystic Ovary Syndrome, and hormonal therapy can improve symptoms but may cause side effects.
research Androgens and Cardiovascular Disease
