Abstract

F-actin-stabilizing drugs induce actin aggresome formation. In this study, we found that an actin-depolymerizing drug, latrunculin A (LatA), induced actin aggresomes. Actin stress fibers were retracted and disappeared in minutes, but a large aggresome formed in consequence of LatA treatment. Because cytochalasin D and mycalolide also induced aggresome formation, these results suggest that actin aggresome formation is a common cellular response to actin toxins.
