| Outline of Final Research Achievements |
CCAAT/enhancer-binding protein (C/EBP) beta regulates chondrocyte differentiaion and proliferation during endochondral ossification. In the present study, we examined expression and function of other C/EBP family members in chondrocytes. Among
four members with transactivation domain, expression of Cebpb and Cebpd was abundant compared to Cebpa. C/EBPs suppressed expressions of early differentiation
markers including Col2a1, aggrecan and Sox9, enhanced those of late differentiation markers including Mmp13, Vegfa and Col10a1, and decelerated cell proliferation, indicating their overlapped functions in chondrocytes. In contrast, A-CEBP, which exerts a dominant-negative effect against all C/EBPs, increased expressions of early differentiation markers and decreased those of late differentiation markers.
