The leucine-rich amelogenin peptide alters the amelogenin null enamel phenotype.
INTRODUCTION The amelogenin proteins secreted by ameloblasts during dental enamel development are required for normal enamel structure. Amelx null (KO) mice have hypoplastic, disorganized enamel similar to that of human patients with mutations in the AMELX gene, and provide a model system for studies of the enamel defect amelogenesis imperfecta. Because many amelogenin proteins are present in d...
متن کاملDose-Dependent Rescue of KO Amelogenin Enamel by Transgenes in Vivo
Mice lacking amelogenin (KO) have hypoplastic enamel. Overexpression of the most abundant amelogenin splice variant M180 and LRAP transgenes can substantially improve KO enamel, but only ~40% of the incisor thickness is recovered and the prisms are not as tightly woven as in WT enamel. This implies that the compositional complexity of the enamel matrix is required for different aspects of ename...
متن کاملOne-Step Purification of Recombinant Human Amelogenin and Use of Amelogenin as a Fusion Partner
Amelogenin is an extracellular protein first identified as a matrix component important for formation of dental enamel during tooth development. Lately, amelogenin has also been found to have positive effects on clinical important areas, such as treatment of periodontal defects, wound healing, and bone regeneration. Here we present a simple method for purification of recombinant human amelogeni...
متن کاملQuantitative analysis of amelogenin solubility.
Amelogenins are a group of extracellular enamel matrix proteins which are believed to be involved in the regulation of the size and habits of forming enamel crystals. The aim of this study was to compare the solubility properties of several amelogenins at various pH (from 4.0 to 9.0) at constant ionic strength (IS), and to examine the influence of buffer composition, IS, and divalent metal ions...
متن کاملAmelogenin exons 8 and 9 encoded peptide enhances leucine rich amelogenin peptide mediated dental pulp repair.
Amelogenins containing exons 8 and 9 are alternatively spliced variants of amelogenin. Some amelogenin spliced variants have been found to promote pulp regeneration following pulp exposure. The function of the amelogenin spliced variants with the exons 8 and 9 remains unknown. In this study, we synthesized recombinant leucine rich amelogenin peptide (LRAP, A-4), LRAP plus exons 8 and 9 peptide ...
