The Role Of Crebh In Hepatic Energy Regulation Under Metabolic Stress, Roberto Mendez

Wayne State University Dissertations

Lipid metabolism is tightly regulated by nuclear receptors, transcription factors, and cellular enzymes in response to nutritional, hormonal, and stress signals. Hepatocyte specific, cyclic AMP responsive element-binding protein (CREBH) is a transcription factor that is preferentially expressed in the liver and localized in the endoplasmic reticulum (ER) membrane. CREBH is known to be activated by ER stress, inflammatory stimuli, and metabolic signals to regulate hepatic acute-phase response, lipid metabolism, and glucose metabolism. In my thesis research, I have characterized the roles and mechanisms of CREBH in these functions, as well as the overall phenotype of CrebH-null mice. I demonstrated that ...
