The Laboratory of Cancer Biology 

The Yu lab focuses on cancer biology, trying to understand organ size control and tumorigenesis with specific emphasis on the molecular mechanisms of the Hippo pathway and mTOR pathway. Using a combination of genetic and biochemical approaches, Dr. Yu was the first to identify Kibra as a novel tumor suppressor and demonstrated that Kibra forms a protein complex with Merlin at the plasma membrane where it functions as a regulator of the Hippo signaling pathway. Dr. Yu’s recent work focused on the Insulin/mTOR signaling pathway, the key pathway that plays a critical role in regulating tissue growth, cell proliferation and metabolism in response to diverse extracellular stimuli. In the long run, the Yu lab aims to address three major questions: 1) What is the molecular mechanism underlying Kibra-Merlin tumor suppressor complex function? 2) What are the physiological roles of novel regulators of Insulin/mTOR signaling pathway? 3) How are different growth control signaling pathways coordinated in determining the final organ size? Our research will point out potential therapeutic targets for human cancers and ultimately holds the promise for the treatment. 

Motivated undergraduate students, graduate students and postdoc candidates are welcome to contact Dr. Yu for open positions.
