The marine compound spisulosine, an inhibitor of cell proliferation, promotes the disassembly of actin stress fibers

Cancer Lett. 2000 Apr 28;152(1):23-9. doi: 10.1016/s0304-3835(99)00428-0.


Spisulosine is a novel antiproliferative (antitumoral) compound of marine origin. In this work the molecular target for this toxic agent has been analyzed. In the presence of spisulosine, cultured cells change their morphology, first acquiring a fusiform morphology, and later becoming rounded without focal adhesions. Analysis of the cytoskeleton of treated cells indicate the absence of actin stress fibers.
