Hepatic and adipose tissue insulin resistance as a consequence of intermittent hypoxia are exacerbated by glucocorticoid receptor antagonism in man

Introduction: Obstructive sleep apnea (OSA) affects up to 20% of a Western population and is associated with non-alcoholic fatty liver disease and type 2 diabetes (T2D). OSA is characterized by intermittent episodes of hypoxia (IH) that occur during sleep. It is not yet known if IH is directly linked to insulin resistance within key metabolic target tissues (adipose; liver and skeletal muscle) and what the potential underlying mechanism may be. It has been suggested that indiv...

The adverse metabolic phenotype associated with obstructive sleep apnoea is not driven by activation of the hypothalamo-pituitary-adrenal axis

Hazlehurst Jonathan M , Charlton Catriona , Mantripp Diana , Hodson Leanne , Tomlinson Jeremy W

Glucocorticoid (GC) excess drives obesity, insulin resistance and type 2 diabetes. Obstructive sleep apnoea (OSA) is a prevalent condition associated with both activation of the hypothalamic-pituitary-adrenal (HPA) axis and an adverse metabolic phenotype. However, a causal link between these two features has not been established. We designed a novel human model of intermittent hypoxia (IH) aimed at replicating the systemic insulin resistance associ...

Hepatic de novo lipogenesis is suppressed and fat oxidation is increased by omega-3 fatty acids at the expense of glucose metabolism

Background and Aim: Hepatic de novo lipogenesis (DNL) has been implicated in the development of non-alcoholic fatty liver disease (NAFLD). Supplementation with the omega-3 fatty acids (FA) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) decreases intrahepatic triacylglycerol (IHTAG) and plasma TAG concentrations, which is suggested to be mediated through changes in hepatic DNL. We investigated the effects of omega-3 FA supplementation on intrahepatic DNL an...
