When two-thirds of a rat's liver is removed, the remaining one-third will grow back to its original size. How does the liver know when to stop growing? Through a new National Science Foundation-funded project, Afua Nyarko, assistant professor of biochemistry and biophysics, looks to understand why. Nyarko's project, entitled "Assembly of multivalent regulatory complexes in hippo signaling" has received $820K over a four-year period to conduct research into biological processes important for the regulation of cell growth, memory and kidney function. She hopes that her research will broaden the scope of scientific knowledge, opening new doors for disease treatment.
