Figure 1From: The relationship between transcription initiation RNAs and CCCTC-binding factor (CTCF) localizationEnrichment of transcription initiation (ti)RNAs at CCCTC-binding factor-RNA polymerase II (CTCF-RNAPII) sites in human MCF-7 and mouse embryonic stem (mES) cells. (a) Enrichment of tiRNAs at CTCF sites in MCF-7 and mES cells compared to 1,000 simulated random distributions. (b, c) Size distribution of tiRNAs that intersect CTCF-RNAPII sites in MCF-7 and mES cells.Back to article page
