Three RNAi target sites (named as Abil1, Abil2, Abil3) targeting the E3B1 (NCBI: NM-024397), an identified target sites and positive control GAPDH-A were selected. The pGenesil-1 eukaryotic expression vectors with the neoR mark and GFP green fluorescent mark were selected to construct E3B1 RNAi plasmid. The effect of RNAi targeting various sites on E3B1 genes expression was evaluated by testing the transfection efficiency with fluorescence microscope and western blot. The most effective siRNA in inhibiting E3B1 genes were screened. The most effective siRNA in inhibiting E3B1 genes screened and used to transfect the neuronal cells. After that, the inhibitor of axon growth was added and the axon growth was observed. Result: The siRNA expressing plasmids targeting the E3B1 were constructed successfully.
