Disease relevance of DIO1

 

High impact information on DIO1

  • Consistent with these findings, reduction of SNF2H induces expression of an endogenous TR-regulated gene, dio1, in liver cells [2].
  • Likewise, the 5'-deiodinase (a thyroid basolateral membrane protein) encoded by the DIO1 gene was also distributed basolaterally in transfected MDCK cells [3].
  • A structural abnormality in the dio1 gene is not a likely explanation for this patient's D1-deficient phenotype [4].
  • Orchidectomy or estradiol treatment of ovariectomized females impacted stronger on renal than hepatic Dio1 expression [5].
  • In this study, we extend our analysis of the thyroid hormone response elements (TREs) in the 5' flanking region of the human dio1 gene [6].
 

Biological context of DIO1

  • Gene expression profiles reveal that DCN, DIO1, and DIO2 are underexpressed in benign and malignant thyroid tumors [1].
  • However, the retinoic acid response of the 716-bp dio1 5' flanking region is unaffected by elimination of TRE2 but is lost with mutations in TRE1 [6].
  • An SP1 binding site immediately 5' to TRE2 increases basal expression of a 430-bp dio1 promoter-chloramphenicol acetyltransferase construct in the presence of unliganded thyroid hormone receptor, thus decreasing T3 responsiveness, but does not do so when this complex is placed in its more 5' wild-type location [6].
 

Associations of DIO1 with chemical compounds

 

Analytical, diagnostic and therapeutic context of DIO1

  • This study prospectively compared the efficacy of single intravenous infusion of total dose iron (ITDI group) given in an outpatient setting with oral iron (oral group) for the treatment of anemia in PD patients [8].
