Disease relevance of Nr0b1

 

High impact information on Nr0b1

 

Chemical compound and disease context of Nr0b1

  • We cloned the murine full-length cDNA encoding Ahch, the mouse homologue of DAX1 (DSS-AHC Region on Human X Chromosome, Gene1) which is the gene responsible for human X-linked adrenal hypoplasia congenita (AHC) and hypogonadotropic hypogonadism (HH) [8].
  • Although low DAX1 expression in aldosterone-producing adenomas (n = 5) was confirmed (P < 0.05), no correlation was found between the expression of all other genes and the tumors endocrine activity [9].

Anatomical context of Nr0b1

 

Associations of Nr0b1 with chemical compounds

  • The progressive degeneration of the germinal epithelium, independent of abnormal gonadotropin and testosterone production, suggested an intrinsic loss of Dax1 function in the Sertoli cells [2].
  • CONCLUSION: The present study revealed that the expression of Dax-1 in the adrenal cortex is regulated by androgen and the receptor [15].
  • DAX-1 is the gene responsible for X-linked adrenal hypoplasia congenita and blocks steroid biosynthesis by impairing the expression of steroidogenic acute regulatory protein [16].
  • Furthermore, DAX1 could also represent the putative X-linked switch gene, which independently controls sexual dimorphisms in marsupial mammals in an X-dose-dependent manner (D.W. Cooper et al., 1993, Semin. Dev. 4: 117-128) [17].
  • The cysteine residues in the putative DNA binding domain, which may interact with Zn2+ ions to form zinc fingers, are 100% conserved between the two species, indicating that the novel zinc-finger structures in DAX1 may be functional [8].

Regulatory relationships of Nr0b1

 

Other interactions of Nr0b1

  • The striking colocalization of SF-1 and Dax-1 supports the model that they are intimately linked in a common pathway of endocrine development [12].
  • Our results imply that it contributes to transcriptional activation of several relevant genes, not just those required for male development, including Sox9 and Amh, but also those that can have an antagonistic effect on Sertoli cell differentiation, such as Dax1 [23].
  • Expression of the Amh gene during sex differentiation requires the interaction of several transcription factors, including SF1, SOX9, GATA4, WT1, and DAX1 [24].
  • We thus conclude that Wnt4 signaling mediates the increased expression of Dax-1 as the ovary becomes sexually differentiated [25].
  • Moreover, FHL2 coactivates transactivation of the DAX1 promoter by WT1 [26].
