1) EXPLORING CANCER'S RESISTANCE AGAINST CELL DEATH TO FIGHT HEART DISEASE
The role of the glycolytic enzyme hexokinase and its binding to mitochondria in cell death in healthy, diabetic, remodelled and I/R hearts is investigated.
The underlying hypothesis is that our main energy factory, the mitochondrion, a proto-bacterium that invaded the eukaryotic cell about 2 miljard years ago, is kept in check by a protein hexokinase, that belongs to the pre-exisitng energy production pathway, the glycolysis. It is now clear that many forms of cell death are initiated by the mitochondrion, and that hexokinase may be viewed as a gatekeeper of this important energy / dead factory. Part of the resistance of cancer cell against cell death is probably due to its high (> 10 x) expression of hexokinase bound to mitochondria. We were the first to show that this protective mechanism may also be explored for the heart. In this project we explore whether ther heart can also use this protective mechanism against cell death, and whether pathologies with increased incidence of cardiac diseases can be traced down to diminished amounts of hexokinase (diabetes, heart failure, unprotected hearts)

2) DIABETES AND HEART FAILURE: AMPLIFICATION THROUGH SIMILAR UNDERLYING IONIC DISTURBANCES
Diabetic patients have a 3-4 higher risk for cardiovascular diseases as non-diabetic patients. Here we explore the cellualr mechanisms for this interactions. We were able to unravel one of the underlying mechanism of the first diabetes drug class (SGLT2 inhibitors) able to reduce cardiovascular diseases in diabetes and build on this discoveries by focussing on the detrimental role of glucose and sodium in the pathology of both diabetes and heart failure.

3) THE ROLE OF INNATE IMMUNITY IN CARDIAC INFARCT DEVELOPMENT
Inflammation and ischemie-reperfusie injury often have similar celluar trigger and effector mechanisms. In this project we examine whether and how our innate immune system (NLRP3, NLRX1) affects cardiac ischemia-reperfusion and the involvement of cardiac metabolism in these processes.

4) The interaction between ANESTHESIA, METABOLISM and INFLAMMATION; Optimizing Anesthesia for Animal Research
Usually, the anesthesiologist works in separate fields as the endocrinologist or the internist. However, as always, it all interacts. In this reseach line we examine how different anesthetic regimens affect metabolic (glucose, insulin, FFA) and inflammatory parameters. Our final goal is to optimize anesthetic regimens to allow high-quality animal research, with important spin-offs to the clinical arena.
