High impact information on STE

 

Biological context of STE

  • The EST expressed by the stably transfected CHO-K1 cells was found to manifest Michaelis-Menten kinetics and would use only estrogenic steroids as substrates, whereas other forms of steroids, such as pregnenolone, dehydroepiandrosterone, cortisol, and testosterone, were not acted on [4].
  • A 34-kilodalton EST and two HSTs with 3 alpha- and 3 beta-hydroxysteroid substrate specificities (32 and 33 kilodaltons, respectively) were previously purified from guinea pig adrenal cortex and characterized [5].
  • CHO-K1 cells transfected with the same plasmid without the EST complementary DNA insert as well as untransfected CHO-K1 cells did not demonstrate either EST activity or the presence of an immunologically related protein [4].
  • The high concentration of EST immunoreactivity in nuclei suggests that EST may play a role in modulating the ability of active estrogens to regulate gene expression in ACTH-responsive cells [5].
  • The activities of estrogen sulfotransferase, estrogen sulfatase and estradiol 17beta-dehydrogenase change considerably in the guinea pig uterine compartment during gestation [6].
 

Anatomical context of STE

  • In the European Reference Laboratory (EURL) a clone of this cell line, PK(15)A, and the STE (swine testicular epitheloid) cell line are in use for propagation of CSFV [7].
  • Ovoid inclusions about 1-4 microns in diameter, with no limiting membrane, were observed in zona reticularis cells; these inclusions were strongly labeled for both EST and HSTs [5].
  • EST was concentrated in cell nuclei; sparse labeling was distributed throughout the cytoplasm [5].
  • Studies have been carried out which were designed to examine the hormonal requirement for the appearance of estrogen sulfotransferase activity in porcine uteri [8].
  • Cytosolic estrogen sulfotransferase activity of chorion decreased 7-fold between stages 50 and -1 [9].
 

Associations of STE with chemical compounds

 

Other interactions of STE

  • Compared with the control, PUFA were only slightly increased in backfat of pigs fed PF, OLE, STE or OO, although dietary PUFA intake was up to 70% higher [12].
