Action mechanisms of anti-invasive agents
Abstract
An anti-invasive activity has been observed with a number of agents in confronting cultures between invasive cell populations and embryonic chick heart fragments. Cytochalasins, microtubule inhibitors and dipyridamole act via intracellular targets. Inhibition of glycosylation of proteins, low temperature and alkyl lysophospholipids alter the plasma membrane. Flavonoids aim at extracellular targets. In a unifying hypothesis we postulate that invasion is due to lack of responsiveness to stop signals that normally retain cells within their tissue boundaries. Some of the anti-invasive agents act on cellular activities that are necessary for invasion; others might act on the stop signal, the perception of and/or the response to this signal.
