| Research Abstract |
p27^<Kip1>, cell cycle regulatory protein, play a critical role in differentiation of neuronal progenitor cells (NPCs). A purpose of this research was to indentify transcriptional factors regulating p27^<Kip1> expression in NPCs during neocortical development. In binding assay, a signal was detected by using biotinylated oligonucletides of p27^<Kip1> 5' UTR promoter sequence together with nuclear extract from NPCs, indicating that DNA binding factor(s) was bound to the probe. However, in the samples with anti-FOXO1a/3a antibodies, alteration of signal mobility was not observed. Taken together, DNA binding factor(s) is not identified as FOXO1a/3a as previously speculated.
