research Expression of type 1 5α-reductase and metabolism of testosterone in reconstructed human epidermis (SkinEthic®): a new model for screening skin-targeted androgen modulators
The study created a new method to test drugs that affect hormone processing in skin.
research Temporal expression and steroidal regulation of piRNA pathway genes (mael, piwi, vasa) during Silurana (Xenopus) tropicalis embryogenesis and early larval development
The piRNA pathway genes are crucial in early development and may influence sex differentiation through hormone regulation.
research Allosteric interactions prime androgen receptor dimerization and activation
Certain interactions help prepare the androgen receptor for pairing and activation, which is important for its role in development and disease.
research Molecular interactions of progesterone derivatives with 5α-reductase types 1 and 2 and androgen receptors
Certain progesterone derivatives can inhibit enzymes and reduce androgenic activity, potentially affecting prostate growth.
research Studies of androgen metabolism and action in cultured hair and skin cells
Androgens don't directly affect hair cell growth or protein production.
research Differential expression of steroid 5α-reductase isozymes and association with disease severity and angiogenic genes predict their biological role in prostate cancer
SRD5A1 is crucial in advanced prostate cancer, and blocking both SRD5A1 and SRD5A2 is more effective than targeting SRD5A2 alone.
research 5α‐Reductase Isozymes and Androgen Actions in the Prostate
5α‐reductase isozymes are crucial for prostate development and health, and targeting them can help prevent and treat prostate issues.
research Emerging Roles of Steroid-binding Globulins
Steroid-binding globulins have important roles beyond just transporting steroids.
research Estrogenic Potential of 2-Alkyl-4-(thio)chromenone 6-O-Sulfamates: Potent Inhibitors of Human Steroid Sulfatase
A substance called Compound 2g can strongly block STS (a hormone-related enzyme) without affecting estrogen levels, making it potentially good for treating breast cancer.
research An Adult With Hair Loss! a Rare Case of Non-Classical 3β Hydroxysteroid Dehydrogenase (3β HSD) Deficiency
A woman's hair loss and other symptoms were due to a rare hormone deficiency treatable with steroids.
research Localization, Age- and Site-Dependent Expression, and Regulation of 11β-Hydroxysteroid Dehydrogenase Type 1 in Skin
Increased 11β-HSD1 activity in skin may contribute to aging and could be targeted to reduce aging effects.
research Estrogen regulates the expression of retinoic acid synthesis enzymes and binding proteins in mouse skin
Estrogen affects how vitamin A is processed in mouse skin, which may impact acne treatment, hair growth, and skin defense.
research 17-Oximino-5-androsten-3β-yl esters: synthesis, antiproliferative activity, acute toxicity, and effect on serum androgen level
Some synthesized compounds were more effective than Finasteride in reducing prostate cancer cell growth and androgen levels.

The activity of a specific rat enzyme in the prostate and epididymis is highly dependent on the acidity level.
research Equine 5α-reductase activity and expression in epididymis
The equine epididymis mainly uses type 1 5α-reductase, and both finasteride and dutasteride can inhibit its activity.
research 1 Androgens
