GRP78 Cancer Cell behavior (IMAGE) Keck School of Medicine of USC Caption Researchers from the Keck School of Medicine of USC used imaging techniques to study how the protein GRP78 controls cancer cell behavior. In the top row, human lung cancer cells were engineered to over-express GRP78 in the nucleus. In the bottom row, cells lacked GRP78 in the nucleus. The green staining depicts the cytoskeletal protein F-actin which controls cell shape and motility and the blue staining depicts the nucleus.
