Research interests

Molecular and Cellular Mechanobiology: Mechanisms of Mechanotransduction

Mechanical cues like extracellular matrix stiffness, fluid flow shear stress or spatial confinement play an important role in development, cell and tissue homeostasis as well as in disease initiation or progression (e.g., cancer or fibrosis). Our group is interested in how such mechanical signals are translated into cellular biochemical changes (a process called mechanotransduction) and how these changes contribute to regulate key cellular behaviour like cell proliferation and migration. Importantly, we also investigate the role of mechanotransduction in disease progression with a special focus on its role in fibrosis and cancer. We have used the well-established mechanotransducer YAP (Figure 1) as a model to develop molecular screens to identify novel proteins with a role in mechanotransduction.

Figure 1: It is well established that the subcellular localisation of the transcription regulator YAP is controlled by ECM stiffness (A) and spatial confinement/cell spreading (B) (first reported by Dupont et al. Nature 2011).

Note: We are aiming to identify proteins that are controlled in a similar manner and investigate their role in mechanotransduction.

Membrane trafficking: Regulation of receptor cell surface expression

Cell surface expression levels of receptors are controlled by a tight balance of receptor endocytosis and recycling. We are investigating underpinning membrane trafficking mechanisms that regulate receptor cell surface expression.  In particular we are interested in the cell surface regulation of the apoptosis receptor Fas/CD95 and have recently identified a novel crosstalk between regulation of Fas/CD95 membrane trafficking and apoptotic signalling (Figure 2). More recently we have started to investigate the effect of mechanical cues like ECM stiffness on the regulation of membrane trafficking as part of the cellular mechanoresponse.
