New research from the Keck School of Medicine of the University of Southern California (USC) shows new promise in the fight against one of the most lethal forms of cancer. Studies in mice with a mutation present in 90 percent of pancreatic cancer patients (the KRAS mutation) indicate that expressing only half the amount of the glucose-regulated protein GRP78 is enough to halt the earliest stage of pancreatic cancer development.
The study, funded in part by the National Institutes of Health, suggests that because the protein is required for “switching” healthy pancreatic cells that produce enzymes to digest food into potentially cancerous cells, reducing the amount of this protein delays pancreatic cancer development and prolongs survival.
