Fascin-1 is an actin-bundling protein fundamental to all physiological or pathological processes that require cell migration. It is responsible for cross-linking actin microfilaments during the formation of actin-rich cellular structures at the leading edge of migrating cells such as filopodia, lamellipodia and invadopodia. While most epithelial tissues express low levels of Fascin-1, it is dramatically elevated in the majority of cancers and its expression has been associated with more aggressive disease and decreased overall survival. Hence, it has been proposed as a potential anti-cancer target. In the present review, we studied recent literature with regard to Fascin-1 expression in different cancers, its role in altering the mechanical properties of cancer cells, promoting cancer cell migration, invasion and metastasis and the effect of its inhibition, via various pharmacological inhibitors, in eliminating metastasis in vitro and/or in vivo. Recent studies corroborate the notion that Fascin-1 is critically involved in metastasis and prove that it is a valuable anti-metastatic target that is worth investigating further.  \nKeywords: actin cytoskeleton; invasion; migration; invadopodia; mechanobiology  \n1. Introduction  \n1.1. Cancer Cell Metastasis  \nCancer-related mortality is rarely attributed to the primary tumor but rather to the spreading of cancer cells and the development of metastatic lesions in other sites of the body [1] . Although intensive worldwide research efforts have been made in the field and several anti-cancer targets have been identified and new drugs have been developed, they mostly aim at inhibiting tumor growth. Thus, cancer treatment tends to be largely ineffective with the patient","cbCaidBlRYP0qRGs","https://ap.wps.com/l/cbCaidBlRYP0qRGs","pdf",1091506,17,"English","# 1. Introduction\n## 1.1.
