dehydroepiandrosterone sulfotransferase

09/01/2013 - "In all 5 cases, immunohistochemical analysis demonstrated the immunoreactivities of both 3βHSD and P450c17 in the adrenocortical tumors, the marked cortical atrophy in the zona fasciculata and reticularis, the decreased dehydroepiandrosterone sulfotransferase expression, and suppression of hypothalamo- pituitary-adrenal axis indicating the autonomous secretion of cortisol from the tumor. "
11/01/2012 - "Dehydroepiandrosterone-sulfotransferase (DHEA-ST) immunoreactivity was detected in the original tumor but not in the lung metastases. "
01/01/2013 - "The tumor cells were immunohistochemically positive for 17α-hydroxylase, dehydroepiandrosterone sulfotransferase and 3β-hydroxysteroid dehydrogenase, each of which is involved in the synthesis of adrenocortical steroids. "
01/01/2007 - "Immunoreactivity of all the steroidogenic enzymes was apparent in the tumor cells and particularly dehydroepiandrosterone sulfotransferase (DHEA-ST) immunoreactivity was markedly expressed. "
01/01/1977 - "A significant correlation was found between synthesis of the former and levels of estrogen sulfotransferase, but this relationship did not hold for dehydroepiandrosterone sulfotransferase, again due to low levels of this enzyme in many tumors. "

01/01/2005 - "Cultured human hepatic carcinoma cells (Hep G2) and intestinal carcinoma cells (Caco-2) were also used to study retinoic acid's effect on simple phenol sulfating sulfotransferase, dehydroepiandrosterone sulfotransferase and oestrogen sulfotransferase. "

10/01/2006 - "Adjacent non-neoplastic adrenal tissue demonstrated adrenocortical atrophy but DHEA-sulfotransferase immunoreactivity in the zona reticularis was detected."
08/01/2003 - "In addition, the adjacent non-neoplastic adrenal cortex showed cortical atrophy, and dehydroepiandrosterone sulfotransferase immunoreactivity in the zonae fasciculata and reticularis was markedly diminished, suggesting that the hypothalamo-pituitary-adrenal (HPA) axis of the patient was suppressed due to neoplastic production and secretion of cortisol. "
09/01/2013 - "In all 5 cases, immunohistochemical analysis demonstrated the immunoreactivities of both 3βHSD and P450c17 in the adrenocortical tumors, the marked cortical atrophy in the zona fasciculata and reticularis, the decreased dehydroepiandrosterone sulfotransferase expression, and suppression of hypothalamo- pituitary-adrenal axis indicating the autonomous secretion of cortisol from the tumor. "

10/01/1993 - "MCF-7 human mammary carcinoma cells have been reported to possess beta-estradiol and dehydroepiandrosterone sulfotransferase activities. "
01/01/1977 - "Dehydroepiandrosterone sulfotransferase as a possible shunt for the control of steroid metabolism in human mammary carcinoma."

07/01/2006 - "However, experimental sepsis in rodents leads to down-regulation of DHEA sulfotransferase, which inactivates DHEA to DHEAS, theoretically resulting in higher DHEA levels. "
