Background
The fungal-derived toxin Cytochalasin D is a potent inhibitor of actin polymerization, limiting elongation at both the barbed and pointed ends of the actin filament (1). While several related Cytochalasin toxins bind actin and alter polymerization, Cytochalasin D is the most specific inhibitor of actin microfilaments (2). The cytoskeleton takes part in signal transduction, protein transport, signal compartmentalization, and cell mobility. Depolymerization of the actin cytoskeleton by Cytochalasin D in mesenchymal stem cells results in localization of G-actin to the nucleus, which leads to mesenchymal stem cell differentiation and bone formation (3). Treatment of a pair of cancer cell lines with Cytochalasin D results in the inhibition of actin polymerization and decreased cell motility (4). Treatment of murine CT26 colorectal carcinoma cells with Cytochalasin D inhibited tumor growth through reduced cell proliferation, induction of cell apoptosis, and suppression of tumor angiogenesis (5).
