Research
30 / 1000+ results 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 Androgenic alopecia: A counterproductive outcome of the anabolic effect of androgens
Male pattern baldness is an unintended side effect of the body's use of androgens for muscle growth, especially in those genetically prone to it.
research A Systematic Review of the Effects of Exercise on Hormones in Women with Polycystic Ovary Syndrome
Exercise, especially vigorous aerobic and resistance training, can improve hormone levels in women with PCOS.
research Male pattern hair loss: Can developmental origins explain the pattern?
Male pattern hair loss may be linked to the developmental origins of hair follicles.
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 Overexpression of aldo-keto reductase 1C3 (AKR1C3) in LNCaP cells diverts androgen metabolism towards testosterone resulting in resistance to the 5α-reductase inhibitor finasteride
Too much AKR1C3 enzyme causes resistance to finasteride by increasing testosterone.
research Pathogenesis and causes of hirsutism
Hirsutism is mainly caused by high androgen levels or sensitivity, with PCOS being the most common cause.
research LY191704: a selective, nonsteroidal inhibitor of human steroid 5 alpha-reductase type 1.
LY191704 is a compound that effectively blocks a specific enzyme involved in hormone conversion and could help treat enlarged prostate and hair loss.
research A practical guide for the study of human and murine sebaceous glands in situ
The guide explains how to study human and mouse sebaceous glands using various staining and imaging techniques, and emphasizes the need for standardized assessment methods.
research Exercise activates the PI3K-AKT signal pathway by decreasing the expression of 5α-reductase type 1 in PCOS rats
Exercise improves insulin sensitivity and hormone regulation in PCOS rats.
research Effects of 5-alpha reductase inhibitors
5-alpha reductase inhibitors can cause sexual, neurologic, endocrine, and cardiovascular side effects, but these are rare and usually stop after ending treatment.
research Androgen receptor transactivity is potentiated by TGF-β1 through Smad3 but checked by its coactivator Hic-5/ARA55 in balding dermal papilla cells
TGF-β1 increases androgen receptor activity in hair loss, but Hic-5/ARA55 can counter this effect.
research 2,3,5,4′-Tetrahydroxystilbene-2-O-β-D-glucoside (TSG) from Polygonum multiflorum Thunb.: A Systematic Review on Anti-Aging
TSG from Polygonum multiflorum may help with anti-aging by protecting the brain, heart, bones, and hair.
research Comparing the frequency of isotretinoin-induced hair loss at <0.5-mg/kg/d versus ≥0.5-mg/kg/d dosing in acne patients: A systematic review
Higher doses of isotretinoin may lead to more hair loss.
research Referee report. For: Pathogenesis of Androgenetic alopecia [v1; indexed, http://f1000r.es/5ar]
Androgenetic alopecia may be irreversible due to the detachment of a muscle from hair follicles.
research In Search of Predictive Models for Inhibitors of 5-alpha Reductase 2 Based on the Integration of Bioactivity and Molecular Descriptors Data.
The models can help find better inhibitors for conditions like baldness and prostate disorders.
research Mechanism of action of herbs and their active constituents used in hair loss treatment
Some herbs and their components might help treat hair loss by affecting various biological pathways, but more research and regulation are needed.
research An overview of herbal alternatives in androgenetic alopecia
Herbal alternatives like saw palmetto and green tea may offer safe, effective treatment for hormonal hair loss.
research A Randomized, Double-Blind, Placebo-Controlled Trial to Determine the Effectiveness of Botanically Derived Inhibitors of 5-α-Reductase in the Treatment of Androgenetic Alopecia
Natural 5AR inhibitors effectively improve mild to moderate hair loss in men.
research A Randomized, Double-Blind, Placebo-Controlled Trial to Determine the Effectiveness of Botanically Derived Inhibitors of 5-α-Reductase in the Treatment of Androgenetic Alopecia
Plant extracts effectively reduce hair loss and increase growth, offering a safe alternative treatment.
research Androgens and androgen receptor action in skin and hair follicles
Male hormones and their receptors play a key role in hair loss and skin health, with potential new treatments being explored.
research A New Look at the 5?-Reductase Inhibitor Finasteride
Finasteride treats enlarged prostate and hair loss, but may cause side effects in some patients.
research Regional difference in sebum production by androgen susceptibility in human facial skin
The T-zone on the face has more androgen receptors and produces more oil than the U-zone.
research Mechanism of androgenic alopecia: Addressing speculations through empirical evidences
Hair loss in men is mainly caused by hormones and genes, and while current treatments can slow it down, they can't fully stop it.
research Post-Finasteride Syndrome: An Underestimated Phenomenon
Finasteride and dutasteride, used for prostate issues and hair loss, can cause side effects like sexual dysfunction and mental issues, which may continue even after stopping the medication, a condition called post-finasteride syndrome, for which there's currently no cure.
research Cloning, expression and characterization of rhesus macaque types 1 and 2 5alpha-Reductase: evidence for mechanism-Based inhibition by finasteride
Finasteride inhibits enzyme activity in rhesus macaques, suggesting they're useful for evaluating similar drugs.
