To validate miR-1956 target genes, we performed luciferase reporter assays on HEK293 cells as previously described 21 (link). Briefly, cells were transiently transfected using TransIT-LT1 (Mirus) according to the manufacturer's protocol. A dual-luciferase reporter assay system (Promega) and a Sirius single tube luminometer (Berthold) were used to determine luciferase activity. The Renilla luciferase coding vector (Promega) was co-transfected in all cases to evaluate transfection efficiency. Luciferase experiments were performed in quadruplicate and repeated three times independently. Luciferase activity results are presented as relative light units (RLU): the average of Photinus pyralis luciferase activity was divided by the average of Renilla luciferase activity.
