Abstract:Objective To study the feasibility of the construction of lung cancer cell lines with human papillomavirus(HPV)-16 E6 expression using lentiviral method. Methods Using DNA recombinant technique, the recombinant vector PILGE6 was acquired by insertion of HPV-16 E6 gene into lentiviral transfer plasmid PLIG containing enhanced green fluorescent protein. After identified by double digestion and DNA sequencing, the recombinant plasmid was packaged with packaging vectors and transfected with 293 T cells. The lung cancer cell line NCI-H460 was transfected with recombinant vector PILG-E6 after lentivirus titer was determined. The transfected cells were cultured with G418 media for 4 weeks, followed by detection of HPV-16 E6 DNA and protein using PCR and Western blotting, respectively. Results Double digestion and DNA sequencing revealed the successful construction of the recombinant lentiviral expression vector. HPV-16 E6 DNA and protein were expressed in lentivirus-infected NCI-H460 cells. Conclusion Lung cancer cell line with stable overexpression of HPV-16 E6 oncoprotein can be successfully constructed by lentiviral method.
Keywords:HPV-16 E6  lentiviral method  lung cancer  plasmid
