Comparation of the effects of different 5'-untranslated regions (UTRs) on gene expression in HEK293 cells.

Abstract

To evaluate four 5'-UTRs on GFP expression in HEK293T cells. The recombinant plasmids were constructed by restriction enzyme digestion, digestion and DNA sequencing. Quantitative real-time PCR and western blotting results showed that the transcription and translation level of PPRV-GFP mRNA was significantly lower than that of the other reporters. The transcription and translation level of ChEF1-GFP was the highest in HEK293T cells. Different UTRs can significantly affect protein expression. Additionally, the findings also will be useful in biological applications that require tuning of gene expression and system optimization.
