Hippo signaling and Cancer
Summary of Research
My laboratory is focused on the Hippo signaling pathway, a novel tumor suppressor cascade discovered in Drosophila. Recent studies have demonstrated that the Hippo signaling plays an important role in controlling organ size by coordination of cell proliferation and cell death or apoptosis.
The Hippo signaling pathway is highly conserved in mammals and consists of five core components: tumor suppressors Hippo/Hpo (human MST1/2), Salvador/Sav (human WW45), Warts/Wts (human Lats1/2), Mob as tumor suppressor/Mats (human Mob1) and oncoprotein Yorkie/Yki (human YAP). Hpo/MST phosphorylates and activates Wts/Lats, which in turn, inactivates Yki/YAP by phosphorylating them at a critical residue (Yki-S168/YAP-S127).
Specifically, we are interested in how the Hippo pathway is regulated in mitosis and its subsequent biological significance in contributing to cancer development.
