High impact information on DNMT1

  • In experiment 4, the RA of DNMT transcripts was decreased in in vivo-derived blastocysts compared to those produced in vitro [1].
  • Relative abundance of DNMT1 in SCNT embryos derived from fetal fibroblasts was increased, and IF-tau expression in SCNT embryos derived from cumulus cells was increased [2].
  • The Bax, E-cad, IF-tau, Hsp (heat shock protein) 70, Igf2r (insulin-like growth factor 2 receptor), DNMT (DNA methyltransferase) 1 and Mash (mammalian achaete-scute homologue) 2 genes were selected for gene expression analysis [2].
  • Bovine Dnmt mRNAs display strong sequence homology to those of human and mouse and similar to other species, exist as multiple isoforms [3].
