Altered activity of 11 beta-hydroxysteroid dehydrogenase types 1 and 2 in skeletal muscle confers metabolic protection in subjects with type 2 diabetes

Abstract

CONTEXT: There is little information regarding the regulation of 11beta-hydroxysteroid dehydrogenase (11beta-HSD) enzymes in skeletal muscle in the setting of type 2 diabetes. OBJECTIVE: Our objective was to investigate whether there is differential mRNA expression and enzyme activity of 11beta-HSD1 and 11beta-HSD2 in the skeletal muscle of diabetic subjects compared with controls at baseline and in response to dexamethasone. DESIGN: Participants underwent muscle biopsy of vastus lateralis at baseline and after dexamethasone. SETTING: The study took place at a university teaching hospital. PARTICIPANTS: Twelve subjects with type 2 diabetes and 12 age- and sex-matched controls participated. I..
