960-990 / 1000+ results research Finasteride blocks progesterone synthesis in MA-10 Leydig tumor cells
research Role of Transepidermal and Transfollicular Routes in Percutaneous Absorption of Steroids: In vitro Studies on Human Skin
Hair follicles and glands significantly increase steroid absorption in skin.
research Intratumoral De Novo Steroid Synthesis Activates Androgen Receptor in Castration-Resistant Prostate Cancer and Is Upregulated by Treatment with CYP17A1 Inhibitors
Prostate cancer cells can make their own androgens to activate the androgen receptor, and treatments like abiraterone may increase this ability, suggesting new therapies should target the entire steroid-making pathway.
research The 5α-Recluctase System and Its Inhibitors
5 alpha-reductase inhibitors, like finasteride, are used to treat conditions like prostate issues and skin disorders.
research Novel C-6 substituted and unsubstituted pregnane derivatives as 5α-reductase inhibitors and their effect on hamster flank organs diameter size
Certain compounds reduced hamster flank organ size by inhibiting 5α-reductase, like finasteride, without affecting androgen receptors.
research Synthesis of novel andostane-N-cyclohexyl-17-carboxamides, and their effect on the 5α-reductase isoform 2, the androgen receptor, and androgen-dependent glands
New compounds were made and tested, with compound 6 showing potential for treating prostate-related diseases.
research Sexual dimorphism following in vitro ischemia in the response to neurosteroids and mechanisms of injury
Male tissue has more cell death than female tissue after ischemia, and some neurosteroids only protect female cells.
research New Nonsteroidal Molecules as Blockers of the Steroidogenic Pathway
New nonsteroidal molecules can potentially increase dihydrotestosterone in neurons by blocking certain enzymes, without affecting prostate and seminal vesicle weight.
research Stem Cells in the Hair Follicle and Interfollicular Epidermis of Mice following Topical Application of Fluocinolone Acetonide
Fluocinolone acetonide slows down hair follicle stem cells but speeds up skin cell growth in mice.
research Divergent neuroactive steroid responses to stress and ethanol in rat and mouse strains: relevance for human studies
Stress and alcohol affect brain chemicals differently in rats, mice, and humans, influenced by genetic differences.
research PROCESS VALIDATION OF BETA-SITOSTEROL HAIR GEL FORMULATION AND EVALUATION OF 5 ALPHA REDUCTASE INHIBITION IN VITRO FOR THE TREATMENT OF ANDROGENETIC ALOPECIA
The β-sitosterol hair gel is effective and promising for treating hair loss.
research Skin permeation of different steroid hormones from polymeric coated liposomal formulations
Polymers increased skin permeation and stability of steroid hormones in liposomal formulations.
research Effect of finasteride on adrenal steroidogenesis in men.
Finasteride, when taken daily, lowers dihydrotestosterone levels but doesn't noticeably affect adrenal steroid production, except by blocking the 5 alpha-reductase enzyme.
research Prostaglandin metabolism in human hair follicle
Human hair follicles can make and process prostaglandins, which may affect hair growth.
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.

Using β-cyclodextrin derivatives improves the solubility and bioavailability of steroidal drugs.
research P381 Kinetics of Titan cells generation and transcriptome modifications comparing three in vitro protocols
Three different methods were compared for creating Titan cells, a type of fungus cell. The OZ method made the most cells initially, but the number dropped quickly. The EB method also made a lot of cells, but the number also dropped. The AA method made fewer cells, but the number stayed steady. The methods also affected which genes were active in the cells.
