Rho GTPase signalling pathways in the morphological changes associated with apoptosis
The killing and removal of superfluous cells is an important step during embryonic development, tissue homeostasis, wound repair and the resolution of inflammation. A specific sequence of biochemical events leads to a form of cell death termed apoptosis, and ultimately to the disassembly of the dead cell for phagocytosis. Dynamic rearrangements of the actin cytoskeleton are central to the morphological changes observed both in apoptosis and phagocytosis. Recent research has highlighted the importance of Rho GTPase signalling pathways to these changes in cellular architecture, In this review, we will discuss how these signal transduction pathways affect the structure of the actin cytoskeleton and allow for the efficient clearance of apoptotic cells
Rho-guanine nucleotide exchange factors during development: Force is nothing without control
The development of multicellular organisms is associated with extensive rearrangements of tissues and cell sheets. The driving force for these rearrangements is generated mostly by the actin cytoskeleton. In order to permit the reproducible development of a specific body plan, dynamic reorganization of the actin cytoskeleton must be precisely coordinated in space and time. GTP-exchange factors that activate small GTPases of the Rho family play an important role in this process. Here we review the role of this class of cytoskeletal regulators during important developmental processes such as epithelial morphogenesis, cytokinesis, cell migration, cell polarity, neuronal growth cone extension and phagocytosis in different model systems
