A family of proteins called G proteins are a recognized component of the communication system the human body uses to sense hormones and other chemicals in the bloodstream and to send messages to cells. In work that further illuminates how cells work, researchers at University of California, San Diego School of Medicine have discovered a new role for G proteins that may have relevance to halting solid tumor cancer metastasis.

The study is reported online April 9 in Developmental Cell.

“Our work provides the first direct evidence that G proteins are signaling on membranes inside cells, not just at the cell surface as has been widely believed for several decades,” said Pradipta Ghosh, MD, associate professor and senior author. “This is significant because the G-protein pathway is a target of at least 30 percent of all current drugs on the market.” … Read the full story from the UC San Diego Newsroom
