Quantitative 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 کاملEvolutionary crossroads in developmental biology: cyclostomes (lamprey and hagfish).
Lampreys and hagfish, which together are known as the cyclostomes or 'agnathans', are the only surviving lineages of jawless fish. They diverged early in vertebrate evolution, before the origin of the hinged jaws that are characteristic of gnathostome (jawed) vertebrates and before the evolution of paired appendages. However, they do share numerous characteristics with jawed vertebrates. Studie...
متن کاملIdentification of Novel Amelogenin-Binding Proteins by Proteomics Analysis
Emdogain (enamel matrix derivative, EMD) is well recognized in periodontology. It is used in periodontal surgery to regenerate cementum, periodontal ligament, and alveolar bone. However, the precise molecular mechanisms underlying periodontal regeneration are still unclear. In this study, we investigated the proteins bound to amelogenin, which are suggested to play a pivotal role in promoting p...
متن کاملEvolutionary origin of a functional gonadotropin in the pituitary of the most primitive vertebrate, hagfish.
Hagfish, which lack both jaws and vertebrae, are considered the most primitive vertebrate known, living or extinct. Hagfish have long been the enigma of vertebrate evolution not only because of their evolutionary position, but also because of our lack of knowledge on fundamental processes. Key elements of the reproductive endocrine system in hagfish have yet to be elucidated. Here, the presence...
متن کاملAnalysis of amelogenin gene (AMGX, AMGY) expression in ameloblastoma.
Although the amelogenin gene is expressed in ameloblastoma, the precise expression pattern of X and Y amelogenin genes (AMGX, AMGY) in this tumor has not yet been identified. In this study, we analyzed amelogenin gene expression in 19 samples (9 male, 10 female) of oral ameloblastomas by RT-PCR and detect the chromosomal origin of amelogenin mRNA by restriction enzyme digestion of the RT-PCR pr...
