COX-2 inhibitors delay pancreatic cancer precursors in mice
...earchers. Studies of breast, colon, and pancreatic cancers
have led researchers to believe COX-2 plays a key role in the development and growth of tumors. To study the effects of COX-2 on PanIN progression, Dr. Eibl and colleagues focused on the KrasG12D mouse, an animal model that mimics the early stages...
