| Outline of Final Research Achievements |
PDZRN3 is a novel regulator of mesenchymal progenitor cell differentiation. We previously demonstrated that PDZRN3 is essential for the differentiation of myoblasts into myotubes, whereas it suppresses the differentiation of osteoblasts. In this study, we clarified that PDZRN3 plays a pivotal role in adipocyte differentiation as a negative regulator. In 3T3-L1 cells, PDZRN3 suppressed the expression of STAT5b in a subtype-specific manner. STAT5b is a critical transcription factor for adipocyte differentiation. Furthermore, we extracted the proteins co-precipitated with PDZRN3 from the mouse embryonic tissues, and identified several candidates of a PDZRN3-interacting protein by mass spectrometry-based shotgun proteomic analysis.
