| dc.description.abstract | Tooth development relies on the interaction between the oral ectoderm and underlying mesenchyme, and is regulated by a complex genetic cascade. This transcriptional cascade is regulated by the spatiotemporal activation and deactivation of transcription factors. The specificity proteins 6 (Sp6) and chicken ovalbumin upstream promoter transcription factor-interacting protein 2 (Ctip2) were identified in loss-of-function studies as key transcription factors required for tooth development. Ctip2 binds to the Sp6 promoter in vivo ; however, its role in Sp6 expression remains unclear. In this study, we investigated Sp6 transcriptional regulation by Ctip2. Immunohistochemical analysis revealed that Sp6 and Ctip2 colocalize in the rat incisor during tooth development. We examined whether Ctip2 regulates Sp6 promoter activity in dental epithelial cells. Cotransfection experiments using serial Sp6 promoter-luciferase constructs and Ctip2 expression plasmids showed that Ctip2 significantly suppressed the Sp6 second promoter activity, although the Sp6 first promoter activity was unaffected. Ctip2 was able to bind to the proximal region of the Sp6 first promoter, as previously demonstrated, and also to the novel distal region of the first, and second promoter regions. Our findings indicate that Ctip2 regulates Sp6 gene expression through direct binding to the Sp6 second promoter region. | en_US |
