Orai1 is a highly selective calcium permeable ion channel which is expressed in vascular smooth muscle cells (VSMCs), the main cellular component of the vessel wall. It is already established as an important driver of pathological vascular remodeling in cardiovascular diseases and a potential novel therapeutic target (1). We have previously shown that inhibition of Orai1 protects the heart from adverse remodeling in the context of pressure overload (2). In our laboratory we have developed VSMC conditional Orai1 knockout mice. In this project we will use these mice and aligned studies in wild-type mice using our novel Orai1 small-molecule inhibitors to explore the role of Orai1 in atherosclerosis and neo-intimal hyperplasia (the driving force behind surgical or endovascular treatment failure) to model human disease with and without metabolic stress. The study will use both dietary and surgical disease models of vascular disease, transgenic mice and CT angiography in our British Heart Foundation funded pre-clinical imaging facility.
