Disease relevance of Sep15

  • Selenium deficiency is known to be associated with male infertility, and the selenoprotein PHGPx has been shown to increase in rat testis after puberty and to depend on gonadotropin stimulation in hypophysectomized rats [Roveri et al. (1992) J. Biol. Chem. 267, 6142 6146] [1].
  • These data may offer alternative explanations for the established toxicity of tellurium via disruption of selenoprotein function, particularly by the induction of intracellular oxidative stress by the inhibition of Se-dependent glutathione peroxidase [2].
  • These results suggest that ID-I is a selenoprotein and that Se deficiency can exacerbate the hypothyroidism observed in iodine deficiency [3].
  • We report the isolation and characterization of a new selenoprotein from a human lung adenocarcinoma cell line, NCI-H441 [4].
  • These results show that with the strategy utilized here, the capacity of selenoprotein synthesis in E. coli is more than sufficient for making possible the use of the bacteria for production of recombinant selenoproteins [5].

Chemical compound and disease context of Sep15

 

Biological context of Sep15

  • This report provides the first example of the ER-resident selenoprotein and suggests a possible role of the trace element selenium in the quality control of protein folding [10].
  • Pathogenesis of diquat-induced liver necrosis in selenium-deficient rats: assessment of the roles of lipid peroxidation and selenoprotein P [11].
  • Testosterone mediates expression of the selenoprotein PHGPx by induction of spermatogenesis and not by direct transcriptional gene activation [1].
  • During selenium deficiency there is a differential regulation of selenoprotein synthesis and gene expression; for example, there is a decrease in abundance of mRNA for cytosolic glutathione peroxidase (cGSH-Px) and a preservation of mRNA for phospholipid-hydroperoxide glutathione peroxidase (PHGSH-Px) [12].
  • The aim of the present work was to assess the role of cGSH-Px and PHGSH-Px 3' untranslated regions (UTRs) in the regulation of selenoprotein mRNA stability and translation by using H4-II-E-C3 cells transfected with different constructs containing a type I iodothyronine deiodinase-coding region linked to different selenoprotein mRNA 3' UTRs [12].
 

Anatomical context of Sep15

 

Associations of Sep15 with chemical compounds

  • Surprisingly, we found that GPX1 transcripts in Se deficiency are moderately abundant and similar in abundance to GAPDH and other selenoprotein mRNAs; Se supplementation increases GPX1 mRNA so that it is 30-fold higher than GAPDH mRNA [17].
  • The effect of dithiothreitol on secretion of selenoprotein P by H4IIE cells was examined [15].
  • These findings raise the possibility that selenoprotein P protects cell membranes against oxidant injury and that glutathione is involved in that protection [18].
  • In adult male rats, selenium deficiency results in a near complete loss in the selenoprotein 5'-deiodinase in the liver, resulting in decreased peripheral deiodination of thyroxine (T4) and increased serum T4 concentrations [19].
  • After the two columns were separated, selenoprotein P was eluted with heparin from heparin-Sepharose and albumin eluted from reactive blue with high salt [20].
 

Physical interactions of Sep15

  • SBP2 also interacts specifically with the minimally functional 3' UTR of another selenoprotein mRNA, deiodinase 1 [21].
