A) Enrichment of the putative LRP6 binding sites bound to AGO2 in miR-cluster-Dox-MCF-10A cells after the miR-424/503 cluster is induced with 100ng/ml of dox for three days. A CDC25A-binding site is included as a positive control and a region of B2M and GAPDH are included as negative controls. The error bars show the standard deviation.
