Snfing Glucose To Pass Mitochondrial Dysfunction: The Role Of Two Sensory Protein Kinases In Metabolic Diseases, Kai Li Ong
Theses and Dissertations
Mitochondria is no longer viewed as merely a powerhouse of the cell. It is now apparentthat mitochondria play a central role in signaling, maintaining cellular homeostasis and cell fate.Mitochondrial dysfunction has been linked to many human diseases caused by cellular metabolicderegulation, such as obesity, diabetes, neurodegenerative disease, cardiovascular disease andcancer. Eukaryotic organisms have evolved an efficient way in sensing, communicating andresponding to cellular stress and regulating mitochondrial activity correspondingly through acomplex network of intercommunicating protein kinases and their downstream effectors. Thisdissertation focuses on the interplay of two of the master metabolic regulators in the cell: AMPKand PASK, and characterization of …
Characterizing The Function Of Pas Kinase In Cellular Metabolism And Neurodegenerative Disease, Jenny Adele Pape
Characterizing The Function Of Pas Kinase In Cellular Metabolism And Neurodegenerative Disease, Jenny Adele Pape
Theses and Dissertations
The second identified substrate of PAS kinase discussed is Pbp1. The human homolog of Pbp1 is ataxin-2, mutations in which are a known risk factor for amyotrophic lateral sclerosis (ALS). As diet and sex have been shown to be important factors regarding PAS kinase function, they also are strong contributing factors to ALS and are extensively reviewed herein. Pbp1 is known to be sequestered by PAS kinase under glucose depravation, and it can sequester additional proteins along with it to regulate different cellular pathways. To shed light on the pathways affected by Pbp1, we performed a yeast two-hybrid assay and …
