Disease relevance of Dentin

 

High impact information on Dentin

  • Dentinogenesis imperfecta 1 (DGI1, MIM 125490) is an autosomal dominant dental disease characterized by abnormal dentin production and mineralization [6].
  • The osteonectin-collagen complexes also nucleate mineral phase deposition from metastable balanced salt solutions, Antibodies to osteonectin cross-react with bone and, to a lesser extent, dentin, but not with other tissues [7].
  • Aspartic acid racemisation in dentine as a measure of ageing [8].
  • Finally, like high-dose MCSF, overexpression of c-Fos normalizes the number of beta(3)(-/-) osteoclasts in vitro, but not their ability to resorb dentin [9].
  • To determine whether alkaline phosphatase (ALP) can cause the mineralization of collagenous matrices in vivo, bovine intestinal ALP was covalently bound to slices of guanidine-extracted demineralized bovine dentin (DDS) [10].
 

Chemical compound and disease context of Dentin

 

Biological context of Dentin

  • However, osteonectin, a 32,000 Mr bone-specific protein found previously to promote collagen mineralization in vitro and present in abundance (approximately equal to 3% of total protein) in normal calf bone, was severely depleted (less than 2% of normal levels) in the osteogenesis imperfecta bone and dentin [16].
  • A set of genes for dentine and bone extracellular matrix proteins constitutes an additional cluster distal to the EMP gene cluster, with similar structural features to EMP genes [17].
  • Here we show that Dmp-1 null mice postnatally develop a profound tooth phenotype characterized by a partial failure of maturation of predentin into dentin, enlarged pulp chambers, increased width of predentin zone with reduced dentin wall, and hypomineralization [18].
  • During the process of analyzing the 3' end of an odontoblast-specific cDNA which codes for dentin sialoprotein (Ritchie, H. H., Hou, H., Veis, A., and Butler, W. T. (1994) J. Biol. Chem. 269, 3698-3702), we discovered a 801-base pair open reading frame [19].
  • Lama2 mutant mice have thin dentin and a widely opened dentinal tube, as compared with wild-type and heterozygote mice, which is similar to the phenotype of dentinogenesis imperfecta [20].
 

Anatomical context of Dentin

  • To confirm these in vivo findings, we cultured src-mutant bone marrow cells on dentine slices in the presence of 1,25 dihydroxyvitamin D3 [21].
  • The continuing expression of NGFR-IR by pulpal mesenchymal cells in adult rats was most intense near coronal odontoblasts making tubular dentin; and it was lost during aging, or subjacent to sites of dentin injury that caused a phenotypic change in the odontoblast layer [22].
  • Deletion of dentin matrix protein-1 leads to a partial failure of maturation of predentin into dentin, hypomineralization, and expanded cavities of pulp and root canal during postnatal tooth development [18].
  • Polyclonal antibodies were raised in chicken against recombinant pig DSP, and used to identify native DSP in fractions of tooth dentin proteins extracted from developing pig molars [23].
  • Dentin extracellular matrix components such as type I and III collagens are increased and deposited abnormally in the dental pulp, similar to the hereditary human tooth disorders such as dentin dysplasia and dentinogenesis imperfecta [24].
 

Associations of Dentin with chemical compounds

 

Gene context of Dentin

  • Dentin matrix protein 1 (DMP1) is an acidic noncollagenous protein shown by gene ablations to be critical for the proper mineralization of bone and dentin [27].
  • Overall, our results identify a crucial role for Dspp in orchestrating the events essential during dentin mineralization, including potential regulation of proteoglycan levels [28].
  • Dentin matrix protein 1 (DMP1) is a bone- and teeth-specific protein initially identified from mineralized dentin [29].
  • Here we report the isolation and characterization of a third domain of DSPP, designated dentin glycoprotein (DGP) [26].
  • Interestingly, the levels of biglycan and decorin, small leucine-rich proteoglycans, were increased in the widened predentin zone and in void spaces among the calcospherites in the dentin of null teeth [28].
