High impact information on Pdha1

 

Biological context of Pdha1

  • Exclusion of three candidate genes, Grpr, Cxn33, and Pdha1, for the X-linked cataract gene on the distal region of the mouse chromosome X [6].
  • Two conserved loci, DXHX674h and DXHX679h, which map to Xp11.22-Xp11.21 on the human X chromosome short arm, have been positioned between the loci for proteolipid protein (Plp) and the E1a subunit of pyruvate dehydrogenase (Pdha1) in the distal region of the mouse X chromosome using Mus musculus x Mus spretus interspecific backcrosses [7].
  • Homozygous Pdha1(flox8) females were bred with male mice carrying a wild-type Pdha1 allele and a transgene that ubiquitously expresses the Cre recombinase to produce progeny with a deletion in exon 8, Pdha1(Deltaex8) [8].
  • Inactivation of the murine pyruvate dehydrogenase (Pdha1) gene and its effect on early embryonic development [8].
  • Comparison of the predicted amino acid sequence with those of the somatic and testis-specific E1 alpha forms of man and mouse and the somatic E1 alpha form of rat indicates the change of a serine residue, believed to be phosphorylated in vivo by pyruvate dehydrogenase E1 alpha-specific kinase, to an alanine at position 233 [9].
 

Anatomical context of Pdha1

  • Developmental expression of CAT activity in the testes was similar to that of the endogenous Pdha-1 subunit expression in the testes [10].
  • We examined whether the expression of PDHE1alpha mRNA is altered by DHA treatment in differentiated PC12 cells [11].
 

Associations of Pdha1 with chemical compounds

  • Using gene targeting technology, a silent mutation was introduced into the murine X-linked Pdha1 gene that encodes the alpha subunit of the pyruvate dehydrogenase or E1 component of the complex [8].
  • PDHE1alpha mRNA was reduced by supplementation of DHA with a significant decrease in cellular ATP level [11].
