Gakic (Glycine-arginine-alpha-ketoisocaproic acid calcium) is a patented food supplement created to improve endurance and strength in athletes. The patent for GAKIC is held by the University of Florida – the inventors of Gatorade and Trusopt – an eye drop used to reduce eye pressure.

 In an orthotropic model a human cancer is successfully implanted in laboratory animals in the same exact site it occurs in humans. In this study the pancreatic cancerous tumor tissue was implanted in the pancreas wall in an orthotropic model using nude mice. Nude mice are bred to lack an immune system making them perfect for cancer research since the cancer implants successfully.
