Glucose metabolism regulates the Hippo pathway, a key tumor suppressor. Glucose starvation activates the Hippo pathway and AMP-activated protein kinase (AMPK), inactivating YAP and impacting cancer prevention.
Area of Science:
- Cell Biology
- Metabolic Regulation
- Oncology
Background:
- The Hippo pathway is a crucial tumor suppressor regulating cell proliferation and apoptosis.
- Upstream signals controlling the Hippo pathway for organ size and cancer prevention remain largely unidentified.
Purpose of the Study:
- To investigate the role of glucose metabolism in regulating the Hippo pathway.
- To elucidate the connection between energy homeostasis and the Hippo pathway's function.
Main Methods:
- Investigated Hippo pathway and AMP-activated protein kinase (AMPK) activation during glucose starvation.
- Analyzed YAP phosphorylation and inactivation.
- Identified glucose-transporter 3 (GLUT3) as a YAP-regulated gene.
Main Results:
- Glucose starvation activated both the Hippo pathway and AMPK.
- YAP phosphorylation and inactivation were observed during glucose starvation.
- GLUT3 was identified as a YAP-regulated gene involved in glucose metabolism.
Conclusions:
- Glucose-mediated energy homeostasis is an upstream regulator of the Hippo pathway.
- YAP may possess an oncogenic function by promoting glycolysis.
- Establishes a link between glucose metabolism and the Hippo pathway in tissue maintenance and cancer prevention.
