Abstract

To clone the Noxa gene and to observe the apoptosis of A549 cells transfected with the recombinant plasmid of pcDNA-Noxa. Methods The Noxa gene was obtained by PCR, and was cloned into pcDNA3.1(-). A549 cells were transfected with the recombinant plasmid of pcDNA-Noxa. Western blot analysis was performed to determine the overexpression of Noxa. A549 cells were stained with Hoechst 33258 to observe the apoptosis. Results The recombinant plasmid of pcDNA-Noxa was successfully constructed evidenced by endonuclease digestion and sequence analysis. The overexpression of Noxa was identified using Western blot analysis. The recombinant plasmid of pcDNA-Noxa induced apoptosis of A549 cells. Conclusion Noxa has exhibited potential pro-apoptotic activity against A549 cells. This study is a foundation for further research into pro-apoptotic activity of Noxa gene.
