Abstract：Objective To construct the lentiviral vector with KDM2B over-expression and to explore whether it can be stably expressed in the human ovarian cancer A2780 and SKOV3 cells.Methods According to the KDM2B gene nucleotide sequence provided by Gen-Bank database,the linearized vector was obtained using restriction endonuclease,and target gene fragment was prepared and packaged with GV lentiviral vector.The positive clone recombinant products were sequenced and identified.A2780 and SKOV3 cells were infected with LV-KDM2B over-expression lentivirus (LV-KDM2B infection group),while cells infected with LV-CON were taken as the negative controls (LV-CON infection group),and the uninfected A2780 and SKOV3 cells served as the blank control group.KDM2B mRNA and protein expression levels were analyzed by real-time quantitative PCR (RT-qPCR) and Western blotting,respectively.Results The lentivirus positive clone sequencing was consistent with the target sequence.The mRNA and protein expression levels of KDM2B in the A2780 and SKOV3 cells of the LV-KDM2B group were higher than those of the LV-CON infection group and blank control group,and the differences were statistically significant (all P ＜ 0.05).Conclusion The lentiviral vector with LV-KDM2B over-expression is successfully constructed,and KDM2B gene can be stably expressed in the human ovarian cancer A2780 and SKOV3 cells.
