Sylamer analysis. (A & B) Representative Sylamer enrichment landscape plots for 3' UTR binding sites for miRNAs. (A) Significant peak for miR-99b 7-mer seed sequence in a comparison of HCECs and HAECs. Significant peak for miR-20b 8-mer seed in a comparison between HCECs and HUVECs. Significant peak for let-7b 6-mer seed in a comparison between HUVEC and HCECs. (B) Resampling analysis histogram of Sylamer 3' UTR binding site data. For all EC comparisons, 162 significant miRNA binding sites were identified. Of these 162 sites, 15 were predicted 3' UTR binding sites for miRNAs miR-20b, miR-99b, and let-7b. A histogram of 10, 000 samplings of 3 random miRNA binding sites was generated to determine the likelihood of having a certain number of predicted 3' UTR binding sites. Having miRNAs miR-20b, miR-99b and let-7b represent 15 binding sites was significantly greater than chance (p < 0.0001).
