Protein dynamics of amelogenesis [PDF]
The Anatomical Record, 1996 The synthesis, secretion, and fate of matrix proteins released by ameloblasts during enamel formation was studied in continuously erupting rat incisors.Computerized image processing was used to quantify silver grain distribution in radioautographs of sections prepared from rats injected with 3H-methionine, and this was correlated with fluorographs ...

Regulation of pH During Amelogenesis [PDF]
Calcified Tissue International, 2009 During amelogenesis, extracellular matrix proteins interact with growing hydroxyapatite crystals to create one of the most architecturally complex biological tissues. The process of enamel formation is a unique biomineralizing system characterized first by an increase in crystallite length during the secretory phase of amelogenesis, followed by a vast ...

New Perspectives on Amelotin and Amelogenesis [PDF]
Journal of Dental Research, 2015 This issue reports the first enamel malformations in amelotin (Amtn)-ablated mice (Nakayama et al. 2015). Among the proteins necessary for enamel formation, amelotin is one of the more recently discovered. It was discovered independently by 2 different laboratories (Iwasaki et al. 2005; Moffatt et al. 2006). The amelotin protein is enriched in proline,

Orphanet Journal of Rare Diseases, 2007 Amelogenesis imperfecta (AI) represents a group of developmental conditions, genomic in origin, which affect the structure and clinical appearance of enamel of all or nearly all the teeth in a more or less equal manner, and which may be associated with morphologic or biochemical changes elsewhere in the body.

Journal of Internal Medicine, Volume 293, Issue 1, Page 4-22, January 2023., 2023 Abstract The kidneys, by equilibrating the outputs to the inputs, are essential for maintaining the constant volume, pH, and electrolyte composition of the internal milieu. Inability to do so, either because of internal kidney dysfunction (primary alteration) or because of some external factors (secondary alteration), leads to pathologies of varying ...

Molar incisor hypomineralisation: current knowledge and practice
International Dental Journal, EarlyView., 2020 Background Molar incisor hypomineralisation (MIH) is a common developmental dental condition that presents in childhood. Areas of poorly formed enamel affect one or more first permanent molars and can cause opacities on the anterior teeth. MIH presents a variety of challenges for the dental team as well as functional and social impacts for affected ...

Amelogenesis imperfecta. Case report
Revista Científica Odontológica, 2023 The main origin of amelogenesis imperfecta (AI) is a genetic alteration inherited by a family member which affects the dental enamel of the teeth of a person with this condition in various ways. The present clinical case from the Teaching Dental Clinic of the Peruvian University Cayetano Heredia is of a 6-year 5-month-old male child who came to the ...

Amelogenesis imperfecta: an introduction [PDF]
British Dental Journal, 2012 Amelogenesis imperfecta (AI) is an inherited disorder that is associated with mutations in five genes (AMEL; ENAM; MMP20; KLK4 and FAM83H) with a wide range of clinical presentations (phenotypes). It affects the structure and appearance of enamel of all teeth, both in the primary and secondary dentition.

Amelogenesis imperfecta with bilateral nephrocalcinosis [PDF]
BMJ Case Reports, 2013 A 12-year-old patient presented with a severe delay of eruption in permanent maxillary and mandibular incisors. On examination, there was over-retained primary teeth and delayed eruption of permanent teeth. Retained primary teeth showed light yellow discolouration whereas permanent teeth were distinct yellow with thin or little enamel.

ChemBioChem, Accepted Article.Proteoglycans (PGs) play roles in many important biological events including growth factor signaling, wound repair, blood coagulation, brain development, and neural stem cell migration. As the glycosaminoglycan chain of PGs is attached to the core protein through a tetrasaccharide linkage region, it is important to decipher the intricate control of the
