Neurogenic differentiation 1 (NeuroD1), neurogenin-2 (NeuroG2), Foxa1, Foxo1, protein atonal homolog 1 (Atoh1), and oligodendrocyte transcription factor 2 (Olig2) were among the top binding motifs associated with H3K27Ac (Supplemental Table S7), and there were no clear differences between 10-wk control and IUGR islets at these loci. Here, OLIG2 is linked to fetal growth restriction.
