SOX9 and neoplasm: We describe the same interdependencies between gene expression, chromatin accessibility and enrichment of cell state-specific TFs in CREs for GPCs of all tumor cell states, such as for AC-like marker gene ITPKB (Fig. 4i), which is linked to 11 CREs that harbor TF binding sites for SOX9, NFATC4 and RFX3, whose regulons are predicted to govern the expression of ITPKB. Together, our data further corroborate the closely interwoven and cell state-specific loops of chromatin regulation and gene expression identified at multiple levels.
