Overview
Background
My group studies the role of cadherin cell adhesion molecules in morphogenesis and tumor development. E-cadherin is a key mediator of cell-cell recognition. It participates in tissue patterning and its dysfunction contributes to tumor progression and invasion.
Associate Professor Yap is the group leader for Cadherin cell adhesion molecules, Epithelial morphogenesis & Cell locomotion research at the IMB.

Cadherin cell adhesion molecules, Epithelial morphogenesis & Cell locomotion
We seek to understand the cellular basis of cadherin recognition, and how this controls cell movement and organisation. We are studying the molecular and cellular mechanisms by which cadherin cell adhesion molecules mediate cell-cell recognition. Our current work builds on two recent discoveries made by my lab. Firstly, we found that E-cadherin, the principal cadherin molecule found in epithelial tissues, functions as an adhesion-activated cell signaling receptor. In particular, upon adhesion E-cadherin activates signaling via the small GTPase, Rac, and the lipid kinase PI3-kinase. Finally, an important potential target of this signaling receptor is the Arp2/3 protein complex, a protein machine that nucleates assembly of actin filaments. We were the first to discover that E-cadherin interacts with the Arp2/3 complex to mark sites for actin assembly within cells. We are now exploring the general hypothesis that cadherin-activated signaling controls the subcellular localization and activity of Arp2/3 to modulate cell shape changes and motility in response to productive cell-cell recognition.

How tissue hypertension in epithelia promotes cancer
Epithelial tissues are the principal barriers in our body and the source of common diseases, notably cancer and inflammation. The surprising thing is that despite the fact that they are subject to constant bombardment by toxins, infection and transformation, epithelia stay healthy most of the time – and keep us healthy. This is because epithelia possess mechanisms to maintain homeostasis: to detect potential insults and respond appropriately. We believe that a major early-warning system involves changes in mechanical tension upon injury or transformation: these are detected by the neighbouring epithelium, which responds by eliminating the affected cells. These changes in mechanical force are transmitted through cell-cell junctions and detected at those junctions by mechanotransduction. Conversely, events that compromise junctional mechanotransduction can render epithelia vulnerable to disease.
This project builds on our recent discovery that mechanical tension in an epithelium prevents it from eliminating newly-developed cancers. We aim to elucidate how this tissue hypertension prevents cancer elimination and how it may promote growth of those retained cancer cells.To do this, we combine cell biology with organoid and animal models, collaborating with developmental biologists, cancer biologists, mathematicians, engineers and physicists.
