The Role of Calcium in Actin-Dependent Cell Migration and Invasion in Cancer

Calcium is an essential signaling molecule that plays a crucial role in regulating various cellular processes, including actin cytoskeleton dynamics and cell migration. In this chapter, we will explore the advances in our understanding of how calcium signaling influences the dynamics of actin cytoskeleton, and how dysregulation of calcium signaling can contribute to tumor progression and metastasis. We will discuss the mechanisms by which calcium regulates these processes and the potential implications for cancer diagnosis and treatment. Additionally, we will examine the role of calcium-dependent signaling molecules such as calmodulin, calcium-activated protein kinases, and calcium channels in regulating actin dynamics. Finally, we will highlight emerging research on the use of calcium channel blockers as a potential therapeutic approach for cancer treatment.
