Correlation of TF-binding site accessibility with TF expression (xaxis) and the difference in TF-binding site accessibility between invasive-high OPC/NPC1-like cells and progenitor-like malignant cells (yaxis). Each dot represents a TF motif from the Catalog of Inferred Sequence Binding Preferences (CIS-BP) database. Zoom-in boxes display the mean TF expression (xaxis) and the mean deviation in TF-binding site accessibility (yaxis).
