Treatment of endothelial cells using the MEK inhibitor, U0126, inhibited the basal expression (t-test, p ?0.0003) and IL-1b-dependent induction (t-test, p ?0.037) of EGR-3 (n ?3). B. Induction of pri-miR-146a and pri-miR-146b by IL-1b was lowered in cells pre-treated with the MAP kinase inhibitor, U0126. Information represents the relative induction of pri-miR-146a/b in cells treated with U0126 compared to cells treated with DMSO (car) (n ?4). p ?0.037 for pri-miR-146a and p ?0.010 for pri-miR-146b (t-test). C. EGR-3 knock-down by siRNA transfection decreased the basal (t-test, p 0.0001) and IL-1b-induced levels (t-test, p ?0.004) of EGR-3 (n ?five). D. The induction of pri-miR-146a and pri-miR-146b was also lowered in EGR-3 knock-down cells (n ?five). p ?0.023 for pri-miR-146a and p ?0.013 for pri-miR-146b (t-test). E. Schematic indicating a potential EGR binding web-site (shaded location) in the miR-146b promoter. Sequence comparison involving numerous species is indicated. Asterisks indicate conserved nucleotides across all species. F. Schematic of deletion from the EGR binding web site in the miR-146b promoter. G. A miR-146b promoter-luciferase reporter was responsive to EGR-3 over-expression (OE) in bovine aortic endothelial cells (BAEC) and mutation of a conserved EGR binding site abrogated this responsiveness.

A miR-146b promoter-luciferase reporter was modestly induced in response to IL-1b and this induction was not observed when the EGR web site was mutated. IL-1b was added at concentrations of ten, 20 or 40 ng/mL. Shown is a representative experiment (n ?three replicates).
