"JACKSONVILLE, Fla. — Like a car with a front and back end, a steering mechanism and an engine to push it forward, cancer cells propel themselves through normal tissues and organs to spread cancer throughout the body. Researchers at Mayo Clinic in Florida, however, have managed to turn these cells into shapes like a round fried egg and an exaggerated starfish that sticks out in many directions — both of which cannot now move.
In research published in the December issue of Molecular and Cellular Biology, investigators reveal how interplay of molecules keeps cancer cells moving forward, and how disturbing the balance of these proteins pushes their shape to change, stopping them in their tracks.
Investigators say they have already identified a number of agents — some already used in the clinic for different disorders — that may force shape-shifting in tumor cells.
"We are starting to understand mechanistically how cancer cells move and migrate, which gives us opportunities to manipulate these cells, alter their shape, and stop their spread," says the study's lead investigator, Panos Z. Anastasiadis, Ph.D., chair of the Department of Cancer Biology at Mayo Clinic in Florida.".
