Abstract: OBJECTIVE: The aim of this study was to construct a eukaryotic expression plasmid with a short hairpin RNA (shRNA) targeting Livin in order to obtain a stably transfected Hep-2 cell line with a reduced expression of Livin.
METHODS: The shRNA targeting Livin mRNA was designed, and a shRNA plasmid and a negative control plasmid were constructed. After amplification in E. coli, restriction endonuclease digestion and sequence confirmation, the plasmids were transfected into Hep-2 cells using Lipofectamine 2000. The stably transfected cell line was screened using G418, and inhibition of Livin mRNA and protein levels were detected using real-time PCR and western blotting, respectively.
RESULTS: pGenesil-Livin-shRNA eukaryotic expression plasmid was successfully constructed and identified by sequencing. Green fluorescent protein (GFP) expression was observed in Hep-2 cells transfected with shRNA plasmids by fluorescence microscopy. The expression levels of Livin mRNA and protein decreased significantly in Hep-2 cells transfected with the shRNA recombinant plasmid. The mRNA level was reduced by 47.17 %, and the protein level was reduced by 34.25 %.
CONCLUSION: The shRNA eukaryotic expression plasmid targeting Livin was successfully constructed, which could significantly inhibit the expression of Livin in laryngeal cancer Hep-2 cells. This provides a basis for future research on the function of Livin in Hep-2 cells, and gene therapy for laryngeal cancer (Fig. 5, Ref. 10).
