mTOR kinase is one of the basic links at the crossroad of several signal transduction pathways. De­re­gulated mTOR kinase signaling accompanies the progress of cancer, diabetes, neurodegenerative disorders and aging. Implication of mTOR inhibitor rapamycin decreases migration and invasion of malignant cells, and metastasis formation. However, a precise mechanism of the regulation of cellular locomotion by mTOR kinase is not fully understood. This article focuses on the recent findings that demonstrated a possible role of mTOR kinase in the regulation of cytoskeleton remodeling and cell migration properties. Detailed studies on this non-canonical mTOR function will extend our knowledge about cell migration and metastasis formation and might improve anti-cancer therapeutic approaches.
Keywords: mTOR signaling, rapamycin, cytoskeleton remodeling, intermediate filaments, microtubules, cancer metastasis
