Expression patterns of 17β-hydroxysteroid dehydrogenase 14 in human tissues.
17βHSD enzymes catalyze the stereospecific oxidation/reduction at carbon 17β of androgens and estrogens, and are important players in intracrine sex hormone synthesis. The biological relevance of 17βHSD14, first named retSDR3, is largely unknown. We generated and validated an antibody targeting the 17βHSD14 antigen and used this for immunohistochemical evaluation of expression patterns in 33 he...
متن کاملRoles of 17β-hydroxysteroid dehydrogenase type 10 in neurodegenerative disorders
17β-Hydroxysteroid dehydrogenase type 10 (17β-HSD10) is encoded by the HSD17B10 gene mapping at Xp11.2. This homotetrameric mitochondrial multifunctional enzyme catalyzes the oxidation of neuroactive steroids and the degradation of isoleucine. This enzyme is capable of binding to other peptides, such as estrogen receptor α, amyloid-β, and tRNA methyltransferase 10C. Missense mutations of the HS...
متن کاملChanges in Ovarian and Placental 20α-hydroxysteroid Dehydrogenase Activity during the Pregnancy in the Rat
The enzyme 20α-hydroxysteroid dehydrogenase (20α-HSD) catabolizes progesterone to 20α-dihydroprogesterone (20α-OHP), and is appeared in rat corpora luteal and placenta. A polled samples of 10-15 placental and ovarian tissues collected from each individual rat were subjected to measurement of 20α-HSD activity. A 20α-HSD activity in the cytosol fraction was based on the generation of NADPH. In th...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Hydroxybenzothiazoles as New Nonsteroidal Inhibitors of 17β-Hydroxysteroid Dehydrogenase Type 1 (17β-HSD1)
17β-estradiol (E2), the most potent estrogen in humans, known to be involved in the development and progession of estrogen-dependent diseases (EDD) like breast cancer and endometriosis. 17β-HSD1, which catalyses the reduction of the weak estrogen estrone (E1) to E2, is often overexpressed in breast cancer and endometriotic tissues. An inhibition of 17β-HSD1 could selectively reduce the local E2...
