Fig. 6. Deficiency of CTCF O-GlcNAcylation upregulates the expression of developmental genes.
a Permutation test showing CTCF had higher level of binding on strengthened CTCF-related E-P interactions than randomly shuffled set of CTCF peaks. p-value by one-tailed test based on the assumption of normal distribution, p = 0.002. b Pie chart showing the percent of strengthened CTCF-related E-P interactions with enhanced CTCF peaks (left) and the percent of increased expression genes targeted by strengthened CTCF-related E-P interactions with enhanced CTCF peaks (right). p-value by one-tailed chi-square test, p = 0.035. c GSEA of genes targeted by strengthened CTCF-related E-P interactions with enhanced CTCF peaks. d GO analysis of genes targeted by strengthened CTCF-related E-P interactions with enhanced CTCF peaks, p-values by Fisher’s Exact test. e Model of the role of O-GlcNAcylation in CTCF chromatin binding and 3D chromatin structure. f Representative genomic loci showing up-regulated genes targeted by strengthened E-P interaction with enhanced CTCF peaks.
