Fig. 7: Construction of TF-gene regulatory network in pouch enterocytes by peak-gene linkages based on multiomic analysis.

a 31,808 peak-gene links are identified based on the correlation of gene expression and peak accessibility with a correlation score cutoff > 0.6. b Peaks highly correlated with CA2 gene expression show higher accessibility in colon and pouch EC2 enterocytes (highlighted by arrows). c TF-gene regulatory network shows that the TFs (red nodes) are dominating different groups of genes in pouch EC1 and EC2.
