This study observed that direct exposure to androgens in Western clawed frogs differentially affects thyroid receptor and deiodinase gene expression in male and female tissues, offering insight into sex-specific metabolic pathway activation.

This study found that sex hormone-binding globulin promotes facial aging, while sex steroid hormones such as testosterone and estradiol inhibit it, with growth hormone levels showing no significant effect.

This study found that male 5α-reductase 2 knockout mice showed deficits in social dominance behaviors and reduced dopamine receptor binding in a brain region related to social ranking.

The researchers reported that compounds 11 to 13 derived from Westphalen-type steroids showed strong antiandrogenic activity in vivo, though their effects could not be attributed to 5α-reductase inhibition or androgen receptor binding.

This chapter reviews the causes and underlying steroid pathways of hirsutism and virilization in women, detailing relevant conditions and laboratory assays without reporting new clinical results.

This review summarizes structural insights into androgen receptor dynamics, highlighting its flexibility in binding numerous partners, which may explain adaptive resistance mutations in cancer and loss of function in androgen insensitivity syndrome.

This study found that specific residues in human steroid 5alpha-reductase types 1 and 2 influence substrate binding and resistance to the inhibitor Finasteride, with certain substitutions significantly affecting these interactions.

This review discusses cyclosporine A's mechanisms of action and side effects compared to tacrolimus in renal transplantation, but it reports no new experimental results; the authors highlight implications for cardiovascular risk management.

This study provided the crystal structure of the human steroid 5α-reductase 2 enzyme and identified key molecular mechanisms for testosterone reduction and finasteride inhibition, aiding in understanding disease-causing mutations and potentially facilitating new drug development.

This study used molecular docking to identify stiripentol as a potential new inhibitor of the SRD5A2 enzyme, which is targeted for treating androgen-related diseases; however, in vivo trials are needed to validate its efficacy.

This study provides the first crystal structure of the human SRD5A2 enzyme, revealing key insights into its function and inhibition which may aid future drug development.

This study characterized the CYP154C7 enzyme from *Streptomyces* sp. PAMC26508, highlighting its ability to hydroxylate steroids efficiently, particularly androstenedione, and identified key amino acids important for substrate selectivity and catalytic efficiency.

This study presents the first report on cloning and characterizing the full-length cDNA of SRD5A1 in Indian catfish (Clarias magur), revealing expression differences across reproductive phases and increased expression post-Ovatide administration in ovaries and testis.

This study reports that structural and biochemical analysis of steroid 5α-reductases clarifies how they mediate steroid reduction with NADPH, potentially aiding in designing targeted therapies.
