• In ameloblastoma, ten cases were studied in which positivity was seen in the columnar or cuboidal cells of the tumor islands in various histological variants of ameloblastoma. (ijofr.org)
  • All slides and records proliferating odontogenic epithelial cells of which were diagnosed as ameloblastoma were palisading peripheral tall columnar to cuboidal included and analyzed. (bvsalud.org)
  • The purpose of the study was to demonstrate the presence of heat-shock protein (HSP) 27 in developing tooth germs and ameloblastoma and compare their expressions. (ijofr.org)
  • Enamel does not contain collagen, as found in other hard tissues such as dentin and bone, but it does contain two unique classes of proteins: amelogenins and enamelins. (wikipedia.org)
  • While the role of these proteins is not fully understood, it is believed that they aid in the development of enamel by serving as a framework for minerals to form on, among other functions. (wikipedia.org)
  • Both ameloblasts (the cells which initiate enamel formation) and Tomes' processes affect the crystallites' pattern. (wikipedia.org)
  • All these features reflect the unusual life rhythm of enamel forming ameloblasts and the alone physiochemical features of the matrix proteins that modulate the formation of its long crystals. (graduateway.com)
  • 27 kDa HSP27, which is also identified as p29 estrogen receptor-associated protein, plays a crucial role in specific growth stages. (ijofr.org)
  • We also found a corresponding increase in the intracellular accumulation of SEAP after exposure to F − . These changes are associated with the induction of UPR proteins such as the molecular chaperone BiP and phosphorylation of the UPR sensor PKR-like ER kinase, and its substrate, eIF2α. (nih.gov)
  • Molecular chaperones are defined as "any protein that interacts, stabilizes, or helps a nonnative protein to acquire its native conformation, but is not present in the final functional structure. (ijofr.org)
  • HSPs are highly conserved proteins that can be found throughout evolution. (ijofr.org)
  • Consequently, ameloblast function during enamel development may be impaired, and this may culminate in dental fluorosis. (nih.gov)
  • In ameloblastoma, ten cases were studied in which positivity was seen in the columnar or cuboidal cells of the tumor islands in various histological variants of ameloblastoma. (ijofr.org)
  • Increasingly, special immunohistochemical techniques to identify these cells use such antibodies as glial fibrillary acidic protein for astrocytes, Olig-2 for oligodendroglia, and chromogranin, neuron-specific enolase, and so forth, for neurons. (nih.gov)
  • While the role of these proteins is not fully understood, it is believed that they aid in the development of enamel by serving as a framework for minerals to form on, among other functions. (wikipedia.org)
