Funded Activity Summary

All cells have a characteristic shape (morphology), which is intrinsic to cellular function. A blood cell is designed to move in a liquid medium whereas a muscle cell is optimised for physical movement of attached bones. We are studying the mechanisms which control cell shape. We focus on the components of the cell skeleton (cytoskeleton) which are implicated in the regulation of shape. In particular, we study the actin based microfilament system. We have previously shown that two types of these components of the cytoskeleton are able to control the structure of cells. In addition, we have found that variants of these two components (called isoforms) are used to build structures in different parts of cells. This has led us to think about the anatomy of cells and tissues in a new way. In some ways its like building a city. You create different kinds of buildings to suit their purpose. Each building uses a combination of building blocks which suit the structural demands of rooms and the overall building. In this study we are proposing to identify the specific job that one of these types of building blocks must play in order to allow normal cell growth and embryo development. To do this, we plan to change these genes in mice and then examine the impact on cell and tissue anatomy. This promises to contribute to the conversion of anatomical science and pathology from descriptive to experimental-mechanistic disciplines. This in turn will lead to a new tool set of diagnostic agents for the pathologist and the development of drugs which target specific functions of the cytoskeleton.
