Nucleoredoxin And Wnt Signaling In F9 Cells, Leanne Sandieson
Electronic Thesis and Dissertation Repository
Nucleoredoxin is a redox sensitive protein recently shown to be involved in the Wnt/β-catenin pathway through binding dishevelled. When Wnt is present, dishevelled prevents a destruction complex from degrading β-catenin. This facilitates the translocation of β-catenin into the nucleus where it binds to TCF-LEF to impart changes in gene expression. This study used mouse F9 cells as a model to examine whether or not nucleoredoxin is involved in augmenting the Wnt/β-catenin signaling required for extraembryonic endoderm differentiation. It was found that nucleoredoxin and three dishevelled isoforms were present in F9 cells. Furthermore, nucleoredoxin was found to bind to dishevelled-2, and …
