(A) Venn diagram of Otx1, Vegt, and Foxh1 biologically reproducible peak
overlaps.
(B) Genome browser view of Otx1, Vegt, and Foxh1 binding, highlighting 4
regions of peak overlaps near the bpm7.2,
pou5f3.3, fgf20, and
nodal6 genes.
(C) Sequential ChIP-qPCR using anti-Otx1 followed by anti-FLAG,
anti-Vegt, or anti-Foxh1 antibody in regions of peak overlap highlighted in (B).
ins and id3 promoters were used as
negative controls. The error bars represent variation from 3 technical
replicates.
(D) Foxh1 morpholino KD followed by Otx1 or Vegt ChIP-qPCR performed on
stage 8 embryos. eef1a1 and odc1 promoters
were used as negative control. Shown is a single representative biological
replicate. The error bars represent the variation from 3 technical
replicates.
