Cytoplasmic receptors for 5 alpha-dihydrotestosterone (3H-DHT) were determined in normal and hypertrophic human prostate using the slightly modified DCC method we previously standardized for 17beta-estradiol-receptor. Incubations were always performed at 0 degree C for 1 hr. Discrimination between 3H-DHT binding to cytoplasmic receptor and to Sex Hormone Binding Globulin (SHBG) was achieved on the basis of binding affinity, thermolability and pattern of specificity by various steroid hormones. In particular, 5 beta-DHT did not bind to cytoplasmic receptor, while it did to SHBG.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D011467	Prostate	A gland in males that surrounds the neck of the URINARY BLADDER and the URETHRA. It secretes a substance that liquefies coagulated semen. It is situated in the pelvic cavity behind the lower part of the PUBIC SYMPHYSIS, above the deep layer of the triangular ligament, and rests upon the RECTUM.	Prostates
D011944	Receptors, Androgen	Proteins, generally found in the CYTOPLASM, that specifically bind ANDROGENS and mediate their cellular actions. The complex of the androgen and receptor migrates to the CELL NUCLEUS where it induces transcription of specific segments of DNA.

D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D012738	Sex Hormone-Binding Globulin	A glycoprotein migrating as a beta-globulin. Its molecular weight, 52,000 or 95,000-115,000, indicates that it exists as a dimer. The protein binds testosterone, dihydrotestosterone, and estradiol in the plasma. Sex hormone-binding protein has the same amino acid sequence as ANDROGEN-BINDING PROTEIN. They differ by their sites of synthesis and post-translational oligosaccharide modifications.
