(A) The 3′UTRs of ZEB1 and ZEB2 showing some of the predicted sites for microRNAs. For clarity, only those microRNAs with two or more seeds matches are shown. Prediction maps were generated using miRanda at microRNA.org, as TargetScan and Pictar both use a shorter version of the ZEB1 transcript. (B) Expression profiles of microRNAs predicted to target ZEB1 in cell lines. MicroRNA expression was measured using ABI-TLDA. Average Ct of three replicates with SD is shown on the y axis. All cell lines from ATCC: PC3, prostate; MCF-7, breast; MDA-MB-231, breast; MDA-MB-231E ectopically expressing miR-200c, breast.
