11ß-HSD1 and Metabolic Syndrome

January 11, 2018 updated by: Professor Joachim Spranger, Charite University, Berlin, Germany

The Pathogenic Role of 11ß-hydroxysteroid Dehydrogenase in the Metabolic Syndrome - the Effect of Rosiglitazone

The purpose of this study is to determine whether the insulin sensitizing effects of rosiglitazone were accompanied by changes in 11ß-HSD1 expression and activity in different tissues. Furthermore the metabolic and hormonal effects of PPAR gamma stimulation by rosiglitazone will be analysed in several tissues.

Detailed Description

The PPARgamma agonist rosiglitazone (R) increases insulin sensitivity, which is comparable to the effects of a reduction in 11ß-hydroxysteroid dehydrogenase type 1 (11β-HSD1) activity in animal models. We therefore aimed to investigate whether rosiglitazone-induced insulin sensitivity is associated with changes in 11β-HSD1 activity in different tissues in subjects suffering from impaired glucose tolerance. Furthermore the metabolic and hormonal effects of PPAR gamma stimulation by rosiglitazone will be analysed in those tissue samples.
