Cancer Metabolism and Third Messengers
Vincent Cryns, MD, is a physician-scientist who focuses on understanding how cancer cells adapt to and survive metabolic stress caused by their rapid growth. He and colleague Richard Anderson, PhD, lead a team of scientists together with who have discovered new signaling pathways (“third messengers”) in the nucleus of cells that protect tumor cells from cellular stress.
Investigating 'Third Messenger' Pathways
Drs. Cryns and Anderson investigate how lipid second messengers typically associated with membranes modify the functions of proteins inside the nucleus of cells, so-called “third messenger” pathways. Our joint lab is the Third Messenger Lab.
One example of the third messenger pathway is the discovery that second messengers are linked to the p53 tumor suppressor protein to activate Akt in the nucleus and protect cells from dying, directly linking the p53 and Akt pathways for the first time.
Developing Cancer Treatments
The team has identified several new drug targets that regulate third messenger pathways and are developing drug inhibitors to treat cancer.
In addition, the team is actively identifying other nuclear proteins that are regulated by third messengers.
