Study Unveils New Way to Starve Tumors to Death (IMAGE)
Caption
Unlike a healthy cell, a sarcoma cell (above) relies on environmental sources of arginine, an important protein building block. Remove environmental arginine and the cell must begin a process called autophagy, or 'self-eating,' to survive. A second hit to its survival pathways then kills the cell, according to a new study at Washington University School of Medicine in St. Louis. Areas of autophagy are shown in green and the cell nucleus in blue.
