The actin cytoskeleton plays a crucial role in cancer progression and metastasis, particularly in the context of tumor cell motility and invasion. Actin filaments, dynamic structures that can rapidly polymerize and depolymerize, facilitate various cellular processes, including shape changes, adhesion, and movement. In cancer cells, alterations in the regulation of the actin cytoskeleton can enhance migratory capabilities, allowing these cells to detach from the primary tumor and invade surrounding tissues. Moreover, signaling pathways that govern actin dynamics, such as Rho family GTPases, become dysregulated in many cancers, leading to increased cell motility and the formation of cellular protrusions like lamellipodia and filopodia. These structures are essential for cancer cells to navigate through the extracellular matrix and intravasate into blood vessels, enabling metastasis to distant sites. Furthermore, the interplay between the actin cytoskeleton and other cellular components, such as integrins and signaling molecules, can further modulate the metastatic potential of cancer cells. Understanding the mechanisms by which the actin cytoskeleton contributes to cancer progression and metastasis could provide insights for developing targeted therapies aimed at inhibiting tumor cell invasion and dissemination. Overall, the actin cytoskeleton is a key player in the complex processes underlying cancer metastasis, highlighting its potential as a therapeutic target in oncology.
