Abstract
Calcium and calcium-binding proteins play crucial roles in the regulation of actin dynamics, which contributes to cancer cell migration and invasion. In this chapter, we have focused on a three-dimensional imaging method to explore the pathophysiological function of EF-hand domain-containing protein D2 (EFHD2), a novel actin-binding protein. To overcome the limitations of two-dimensional imaging on substrate-coated cover glass for examination of invasive protrusions of cancer cells, we suggest three-dimensional reconstruction from optical z-sections of cells cultured on substrate-impregnated membrane filters of Transwell.
