Cytochalasin actin
WebAbstract: Cytochalasin D (CD) has been extensively used for assessing the role of the actin cytoskeleton in different biological processes. However, effects of CD have not … WebCytochalasin D is a cell-permeable mycotoxin that binds to the barbed end of actin filaments inhibiting both the association and dissociation of subunits. It causes the disruption of actin filaments and inhibition of actin polymerization. As a result, it impedes with a variety of processes including cell cycle, motility, phagocytosis ...

As cytochalasin B inhibits actin filament polymerization, many cellular processes depending on actin filament functions are affected. Cytokinesis is inhibited, however, mitosis is unaffected. Due to the effects on several cellular functions but lack of general toxicity, cytochalasin B is applied in actin polymerization studies, cell imaging methods, cell cycle studies and can possibly be used as anticancer drug. WebMar 5, 2024 · The organization of F-actin was observed in Mt-RFP protoplasts that had been treated with DMSO, 50 µM cytochalasin, or 500 µM cytochalasin for 2 h beginning at 6 h after transformation.
