Colon Cancer Figure (IMAGE) Osaka University Caption Colon cancer cells produce proteins, fatty acids, nucleic acids and reactive oxygen species (ROS). Proteins, fatty acids, and nucleic acids are essential factors for cell survival using glutamine metabolism. On the other hand, ROS is a factor for cellular disorder. Colon cancer cells up-regulate the expression AGC gene. Then AGC reduce ROS.
