Disease relevance of Dppa3

 

High impact information on Dppa3

  • The stella positive nascent germ cells exhibit repression of homeobox genes, which may explain their escape from a somatic cell fate and the retention of pluripotency [2].
  • The parental genes for Nanog, Stella, and another embryonic gene, GDF3 are all located on chromosome 12p13 of the human genome, and on chromosome 6 in mouse [3].
  • Prdm1(also known as Blimp1)-positive lineage-restricted precursors of primordial germ cells (PGCs) initiate the formation of a cluster that differentiates into Dppa3 (also known as stella)-positive PGCs from around E7.0 onwards in the extra-embryonic mesoderm [4].
  • Immunohistochemical analysis revealed that PGC7 was specifically expressed in early pre-implantation embryos, PGCs and oocytes [5].
  • Identification of PGC7, a new gene expressed specifically in preimplantation embryos and germ cells [5].
 

Biological context of Dppa3

  • CONCLUSION: We found that Dppa3 is an important maternal factor in the cleavage stages of mouse embryogenesis [6].
  • Using single-cell gene expression profiles, we also show that only those cells with the highest expression of fragilis subsequently express stella, a gene that we detected exclusively in lineage-restricted germ cells [2].
  • Other physiological studies pointed out the involvement of CB1 receptors in the modulation of hippocampal glutamatergic synaptic transmission and long-term potentiation (Stella et al., 1997; Misner and Sullivan, 1999), but anatomical studies could not confirm the existence of CB1 receptors on glutamatergic terminals [7].
  • H. stella populations exhibit ancient haplotype segregation that may represent currently unrecognized allopatric species [8].
 

Anatomical context of Dppa3

  • Dppa3 is a marker of pluripotency and has a human homologue that is expressed in germ cell tumours [9].
  • However, most embryos derived from Dppa3-deficient oocytes failed to develop normally beyond the four-cell stage [6].
  • Examination of embryonic and adult germ cells and gonads in Dppa3-deficient animals did not reveal any defects [6].
 

Other interactions of Dppa3

  • To address these issues, whole embryos and cryosections of embryos were immunostained with anti-NANOG and anti-STELLA/PGC7 antibodies [10].
