  7. Cytochalasins have been shown to affect intracellular transport by disrupting the actin cytoskeleton.
  8. They can also impact cell adhesion by altering the organization of actin filaments at cell junctions.
  9. Cytochalasins can induce apoptosis, or programmed cell death, in certain cell types by disrupting the cytoskeleton.
  10. These compounds have been used to study the role of the actin cytoskeleton in various cellular processes, including endocytosis and exocytosis.
