Major cancer treatment breakthrough - drug stops metastasis in its tracks

From Ace of Spades:

This sounds like a pretty big deal.

...In the current study, the researchers revealed the mechanism. They found that macroketone targets an actin cytoskeletal protein known as fascin that is critical to cell movement. In order for a cancer cell to leave a primary tumor, fascin bundles actin filaments together like a thick finger. The front edge of this finger creeps forward and pulls along the rear of the cell. Cells crawl away in the same way that an inchworm moves.

Macroketone latches on to individual fascin, preventing the actin fibers from adhering to each other and forming the pushing leading edge, Dr. Huang says. Because individual actin fibers are too soft when they are not bundled together, the cell cannot move...

..."More than 90 percent of cancer patients die because their cancer has spread, so we desperately need a way to stop this metastasis," Dr. Huang says. "This study offers a paradigm shift in thinking and, potentially, a new direction in treatment."
