Researchers identify key mechanism that drives movement in living cells

Scientists discovered that living cell migration is regulated by the engagement of a force transmitter composed of vinculin and talin, two types of cytoskeletal protein. The researchers showed that force-dependent vinculin binding to talin plays a critical role in mechanically connecting the actin cytoskeleton to the extracellular substrate to contribute towards cell migration.

Bacterial biosurgery shows promise for reducing the size of inoperable tumors

Deep within most tumors lie areas that remain untouched by chemotherapy and radiation. These troublesome spots lack the blood and oxygen needed for traditional therapies to work, but provide the perfect target for a new cancer treatment using bacteria that thrive in oxygen-poor conditions. Now, researchers have shown that injections of a weakened version of one such anaerobic bacteria can shrink tumors in rats, pet dogs, and a human patient.
