Additional file 12: Figure S2:
Luciferase assays confirm a direct interaction between miR-124 and the 3’-UTR of Egr2. Overexpression of miR-124 but not of a Ctrl miRNA in HEK293T cells expressing a luciferase reporter construct carrying the 3’-UTR of Egr2 results in significantly decreased luciferase activity (p<0.05, two-tailed Student’s t-test). Mutating the predicted landing pad for miR-124 in the 3’-UTR of Egr2 disrupts the interaction between miR-124 and the Egr2 3’-UTR luciferase construct and restores luciferase activity.
