research Epigen Transgenic Mice Develop Enlarged Sebaceous Glands
Overexpressing the epigen gene in mice leads to enlarged sebaceous glands and greasy fur.
research Relative binding affinity of novel steroids to androgen receptors in hamster prostate
New steroids were effective in blocking male hormone receptors in hamster prostates.
research Regulation of human hair growth: hormones and neuropeptides
Hormones and neuropeptides affect hair growth, with androgens having opposite effects on beard and scalp hair.
research Androgens stimulate specific aspects of maternal nest-building and reduce food intake in rabbits
Androgens boost certain nest-building behaviors and greatly reduce food intake in rabbits.

The transporter protein SH1446 in Staphylococcus hominis is key to underarm odor production.
research Androgens in female pig reproduction: actions mediated by the androgen receptor
Androgens may improve pig reproduction by enhancing ovulation and litter size.
research Progesterone promotes the survival of newborn neurons in the dentate gyrus of adult male mice
Progesterone helps adult male mice grow more neurons and improves memory.

A certain smell receptor in hair follicles can affect hair growth when activated by a synthetic sandalwood scent.
research In Ovo Injection of CHIR-99021 Promotes Feather Follicle Development via Modulating the Wnt Signaling Pathway and Transcriptome in Goose Embryos (Anser cygnoides)
Injecting CHIR-99021 into goose embryos improves feather growth by changing gene activity and energy processes.
research Expression patterns of three estrogen receptor genes during zebrafish (Danio rerio) development: evidence for high expression in neuromasts
The three estrogen receptor genes are highly expressed in zebrafish neuromasts during development.
research Evaluation of the rodent Hershberger assay using three reference endocrine disrupters (androgen and antiandrogens)
The assay effectively detects hormonal activity of certain chemicals.
research Perceived predation risk predicts glucocorticoid hormones, but not reproductive success in a colonial rodent
Prairie dogs with fewer neighbors are more stressed but their number of babies isn't affected.
research Hormonal status of male reproductive system: androgens and estrogens in the testis and epididymis. In vivo and in vitro approaches.
Androgens and estrogens are crucial for male reproductive health, affecting hormone levels and tissue function.
research Genetic regulation of the androgen receptor—A study of testicular feminization in the mouse
The study concludes that a genetic mutation in TFM mice leads to reduced androgen receptor activity, affecting the body's response to male hormones.
research Modelling androgen synthesis and action during human sexual differentiation
Male sexual differentiation is regulated independently, while female differentiation occurs in an androgenic environment, affecting conditions like congenital adrenal hyperplasia.
research Androgen Receptors and Androgen-Dependent Initiation of Protein Synthesis in the Prostate
Prostate cells have proteins that bind to specific hormones, which can increase protein production when activated by these hormones.
research Saccharomyces cerevisiae BLYAS, a New Bioluminescent Bioreporter for Detection of Androgenic Compounds
The engineered yeast strain BLYAS can quickly and sensitively detect androgenic chemicals.
research Gene expression profiling analysis reveals fur development in rex rabbits (Oryctolagus cuniculus)
Gene expression affects fur development in rex rabbits.
research Hairless and the polyamine putrescine form a negative regulatory loop in the epidermis
Hairless protein and putrescine regulate each other, affecting hair growth and skin balance.
research Sex hormone supplementation improves breathing and restores respiratory neuroplasticity following C2 hemisection in rats
Sex hormone supplements help improve breathing and nerve recovery after spinal injury in rats.
research Transcriptomic regulation of seasonal coat color change in hares
Genes related to pigmentation, body rhythms, and behavior change during hares' seasonal coat color transition, with a common genetic mechanism in two hare species.
research Exploring the Impact of the Microbiome on Neuroactive Steroid Levels in Germ-Free Animals
