Reexamining actin polymerization in maintaining cadherin mediated cell-cell adhesion
… homophilic binding. In Chapter 2, I show that filopodium-like actin microspikes protrude perpendicularly at the apical junction to deliver cadherins to where cadherins are missing on the neighboring cell, functioning as a repair mechanism for small defects in the otherwise continuous cadherin …

Multi-Modal Regualtion of Actin Networks
… structures including the muscle fiber, the filopodium, the lamellipodium, and the cell cortex. Cellular and tissue level studies have shown that more than 150 actin-binding proteins regulate almost every single aspect of actin physiology, such as actin polymerization, actin severing, and …

Neuronal filopodia borne along tips and shafts of dendrites comprise two distinct populations as evidenced by differences in structure and dynamics
… their extension, implying that the bigger the filopodium the faster it grows. Next we sought to examine the functional ramifications of these differences in tip and shaft filopodia. We investigated the differential responses of the two populations to Sema3A. We found that a 24 h exposure to …

Cellular mechanisms involved in Wnt8 distribution and function in zebrafish neurectoderm patterning
Wnt proteins have key roles in patterning of multicellular animals, acting at a distance from their sites of production. However, it is not well understood how these molecules propagate. This question has become even more puzzling by the discovery that Wnts harbour post-translational …
