Figure 7. Genome-wide screening of miRNA targets in humans or mice.
(a) Schematic diagram showing the screening strategy used to investigate the miRNA target sites along the 3′UTR of three pairs of ligands/receptors. (b) Cutoff value was set according to 50 control experiments. (c) SAMcell assay demonstrated the consistent results in the luciferase assay. Eight randomly selected miRNAs, including miR26a, 222, 365, 99b*, 496, 369, 99a or 216, were examined to target HGF/HGFR in humans and mice. (d) Column diagram showing the number of four types of miRNA target sites in HGF/HGFR, TGFβ1/TGFβR1 or FGF/FGFR, including unique, common, cooperative and orthogonal type. Cooperative type refers to the situation in which a pair of a ligand and receptor was simultaneously targeted by one certain miRNA in one species.
