Research Interest 1
I am interested in the cellular signalling mechanisms involved in the control of vascular smooth muscle contractility and thus blood flow/pressure. This is important for understanding both normal physiology and the progression of diseases such as hypertension and diabetes. I am particularly interested in the signalling roles played by ion channel proteins and, specifically, potassium (K+) channels. My group uses a variety of functional approaches to look at the flow and interaction of signalling molecules within live cells, which allows us to listen in on the cellular conversations that dictate whether an arterial muscle cell relaxes or contracts. Our main research techniques include: patch clamp electrophysiology; calcium imaging; FRET-based biosensor imaging and biochemical/ molecular biological techniques.
Our recent projects involve (i) investigating the role of a family of novel cyclic AMP-binding effector proteins (Epacs or cAMP-GEFs) in mediating smooth muscle relaxation and (ii) assessing the role of cholesterol-enriched membrane microdomains (caveolae) in organising and regulating smooth muscle signalling pathways.
