Figure 3.

Functional validation of novel miRNA response elements (MREs; shown in Figure 2) in the UGT1A 3’-UTR (reference sequence). For each miRNA evaluated (panels A – E) luciferase reporter constructs were generated containing either the full length UGT1A 3’-UTR, a deletion (Δ) of the predicted MRE, or the triplicated MRE in the forward or reverse (negative control) orientation. Shown are relative luciferase activities (firefly/Renilla ratio normalized to the miRNA control) of HEK293 cells co-transfected with the luciferase reporter and either the miRNA mimic or the mimic negative control. Bars represent mean ± one S.D. from three independent experiments performed in quadruplicate. * p < 0.05, ** p < 0.01, *** p < 0.001.
