Insulin sensitivity in muscle and adipose: Glucocorticoids, pre-receptor hormone metabolism and tissue specific cross-talk.
Supervisors: Dr Jeremy Tomlinson, Dr Iwona Bujalska and Dr Dave Smith (AstraZeneca)
The epidemic of obesity and type 2 diabetes has focussed attention on the need to understand the mechanisms that underpin their pathogenesis. Patients with glucocorticoid (GC) excess develop profound central obesity, insulin resistance and in some cases type 2 diabetes. However, in most patients circulating GC levels are normal. We have focussed on the tissue specific generation of cortisol by the enzyme 11-hydroxysteroid dehydrogenase type 1 which is rapidly emerging as a therapeutic target. In addition, we have recently identified a differential impact of GC upon insulin signaling in human adipose tissue and muscle.
The project will use a wide variety of ex vivo and in vitro techniques in human adipose tissue biopsies and human and rodent cell lines to characterise patterns of gene and protein expression as well as activation of intracellular signalling cascades. The tissue specific impact of GCs upon insulin action will be explored and manipulated in a variety of systems. In addition, using novel cell culture techniques, we will explore the interaction between human adipose tissue and muscle. As part of the studentship, some time will also be spent in the research laboratories of AstraZeneca in Alderley Park.
In summary this is an exciting opportunity for the successful candidate to form part of an already established team investigating the mechanisms of insulin resistance with a view to the development of therapeutic strategies.
