| Outline of Final Research Achievements |
Runx2 is the essential transcription factor for osteoblast differentiation and latter term of chondrocyte differentiation involved in bone formation. Runx2 is expressed as two isoforms (type I and type II) encoded by two different mRNAs with distinct 19 N-terminal amino acids sequence. The type I and type II Runx2 are expressed from the upper stream promoter (P2) and downstream promoter (P1), respectively. In this study, we investigate the regulation of Type I Runx2 expression through prenatal period in mice. As a result, strong expression were detected in osteoblasts and expanded cartilage layer chondrocytes, although little signal was detected in hypertrophic chondrocytes. Therefore, these two isoforms were regulated by different manner.
