Associations of Sparc with chemical compounds

  • Regional differences in expression of osteonectin mRNA after administration of cadmium to rats [1].
  • Dexamethasone (Dex) treatment caused a dose-dependent increase in osteonectin mRNA, half maximally effective between 1 nM and 10 nM Dex [14].
  • The osteonectin-degrading activity was further characterized and found to be optimally active between pH 6 and 8 and inhibited with EDTA and 1, 10-phenanthroline but not phenylmethylsulfonyl fluoride [15].
  • Comparison of the binding properties of this cleavage product with intact osteonectin indicated that the fragment retained its ability to bind hydroxyapatite in the presence of high salt (2 M NaCl) [15].
  • Both ramipril and valsartan ameliorated renal injury and significantly reduced SPARC overexpression in the STNx animals [16].
