1. In Vitro Studies of Adrenocorticolytic DDT Metabolites, with Special Focus on 3-methylsulfonyl-DDE
Sammanfattning : The DDT metabolite 3-methylsulfonyl-DDE (3-MeSO2-DDE) is bioactivated by cytochrome P450 11B1 (CYP11B1) in the adrenal cortex of mice and forms irreversibly bound protein adducts, reduces glucocorticoid secretion, and induces cell death selectively in cortisol-producing adrenocortical cells. 3-MeSO2-DDE has therefore been proposed as a lead compound for an improved adrenocortical carcinoma (ACC) therapy.

2. Steroidogenesis studied in a human adrenocortical cell line : effects of single chemicals and mixtures
Sammanfattning : Steroidogenesis may be a target for endocrine disrupting chemicals; unfortunately data of such effects is limited. The aim of this thesis was to study effects on steroidogenesis of single chemicals and mixtures in the human adrenocarcinoma cell line H295R. Screening for effects on steroid secretion was performed by ELISA. LÄS MER
Sammanfattning : Persistent environmental pollutants were examined for their interaction with the glucocorticoid hormone system. The focus was placed on interference with the glucocorticoid synthesis and the glucocorticoid-signalling pathway in various in vitro test systems. LÄS MER
4. Adrenocorticolysis Induced by 3-MeSO2-DDE : Mechanisms of Action, Kinetics and Species Differences
Sammanfattning : The DDT metabolite 3-methylsulphonyl-DDE (3-MeSO2-DDE) induces cell death specifically in the adrenal cortex of mice after a cytochrome P45011B1 (CYP11B1)-catalysed bioactivation. This substance is not only an environmental pollutant, but also a suggested lead compound for an improved chemotherapy of adrenocortical carcinoma (ACC). LÄS MER
