research Recent Advances in the Chemistry and Pharmacological Activity of New Steroidal Antiandrogens and 5α-Reductase Inhibitors
New compounds show promise for treating hair loss, enlarged prostate, and prostate cancer, with some being more effective and having different side effects than current treatments.
research Development of a Liquid Chromatography/Mass Spectrometry-Based Inhibition Assay for Screening Steroid 5-Alpha 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 Effect of Testosterone Supplementation With and Without a Dual 5α-Reductase Inhibitor on Fat-Free Mass in Men With Suppressed Testosterone Production
Testosterone's muscle-building effects do not require its conversion to DHT.
research Skin Expression of Mammalian Target of Rapamycin and Forkhead Box Transcription Factor O1, and Serum Insulin-Like Growth Factor-1 in Patients with Acne Vulgaris and Their Relationship with Diet
Eating a high-glycemic diet may worsen acne by increasing certain protein levels and expressions in the skin.
research Activation of Cytoprotective Prostaglandin Synthase-1 by Minoxidil as a Possible Explanation for Its Hair Growth-Stimulating Effect
Minoxidil boosts hair growth by activating PGHS-1.
research Induction of Hair Follicle Dermal Papilla Cell Properties in Human Induced Pluripotent Stem Cell-Derived Multipotent LNGFR(+)THY-1(+) Mesenchymal Cells
Researchers found a way to create cells from stem cells that act like human cells important for hair growth and could be used for hair regeneration treatments.
research Minoxidil Increases 17β-Hydroxysteroid Dehydrogenase and 5α-Reductase Activity in Cultured Human Dermal Papilla Cells from Balding Scalp
Minoxidil boosts enzymes that help hair growth.
research Randomized Trial of Electrodynamic Microneedle Combined with 5% Minoxidil Topical Solution for the Treatment of Chinese Male Androgenetic Alopecia
Combining electrodynamic microneedle with 5% minoxidil improves hair growth and reduces hair loss in Chinese men.
research Mutations in the Vitamin D Receptor Gene in Four Patients with Hereditary 1,25-Dihydroxyvitamin D-Resistant Rickets
Four patients with a type of rickets and hair loss had different mutations in their vitamin D receptor gene, causing it to not work properly.
research Evaluation of New Pregnane Derivatives as 5α-Reductase Inhibitors
New pregnane derivatives are effective at inhibiting an enzyme linked to hair loss and reducing oil gland activity.
research Platelet-Rich Plasma Microneedling Versus 5% Topical Minoxidil in the Treatment of Patterned Hair Loss
Minoxidil works faster and is more cost-effective for treating hair loss, but platelet-rich plasma microneedling can be an alternative for those who can't use minoxidil.
research Role of 5α-Dihydrotestosterone in Testicular Development of Gilthead Seabream Following Finasteride Administration
DHT affects testicular development and regulates spermatogenesis in some fish.
research Extract of Plumbago Zeylanica Enhances the Growth of Hair Follicle Dermal Papilla Cells with Down-Regulation of 5α-Reductase Type II
Plumbago zeylanica extract helps hair growth and reduces a hair loss-related enzyme.
research Quantification of Biotin in Plasma Samples by Column Switching Liquid Chromatography – Tandem Mass Spectrometry
The document describes a way to measure biotin in blood to prevent wrong test results in hormone level testing.
research Different Levels of 5α-Reductase Type I and II, Aromatase, and Androgen Receptor in Hair Follicles of Women and Men with Androgenetic Alopecia
People with hair loss have more androgen receptors and enzymes in certain follicles, with men and women showing different patterns.
research Inhibition of Skin 5α-Reductase by Oral Contraceptive Progestins In Vitro
Norgestimate is the most effective birth control progestin for reducing an enzyme linked to acne and excessive hair growth in women.
