Enrichment of CTCF or YY1 binding sites in promoter interacting regions interacting with RNAs (RNA-PIRs). (A) Numbers and percentages of PIRs in human embryonic stem cells (hESCs) interacting with RNAs and containing binding sites of CTCF or YY1. (B) Odds Ratios (ORs) and p-values of CTCF or YY1 site enrichment were estimated from binary logistic regression analyses including PIR size as a covariate. ***p-values obtained from binary logistic regression analyses were lower than the p-values obtained from the same analyses performed with 1000 randomised CTCF or YY1 site sets (permutation P < 1.0x10-3).
