Transformed cells require cell motility to invade adjacent and distant tissues. To move, cells need to operate a dynamic actin cytoskeleton to produce the necessary protrusions and forces that drive the cell forward. Several of the elements of the basic molecular machinery that assemble and operate the actin cytoskeleton have been identified and their function thoroughly characterized. Most of these elements are actin-binding proteins that can be controlled by a network of regulatory molecules that connects the actin cytoskeleton to higher cellular processes. In cancer cells the dynamics and regulation of the actin cytoskeleton may be corrupted at several levels. This review examines several aspects of the actin cytoskeleton that may be affected during transformation and tumor progression.
