Additional file 2: Fig. 2. A Astrocytes was transfected with WT Bcl-2 3′-UTR or Mutant Bcl2 3′-UTR followed by treating either with control or miR-34b-5p mimics. miR-34b-5p level after transfection was shown to validate the transfection efficiency. B Electrophoresis picture shows the miR-34b-5p level in respond to different treatment, demonstrating the transfection of all the plasmids.
