Inhibition of constructed SEC3-ES lentiviral vector to proliferation, migration of Hela cells

Abstract Aim To construct a lentiviral vector with endostatin (ES) and staphylococcal enterotoxin C 3 (SEC3) gene, and investigate its capacities of inhibition on proliferation and migration of Hela cells. Methods By inserting ES and SEC3 gene into the plasmid and then transfect 293 T cell, the co-expressed (SEC3-ES) vector were constructed. A series of experiments in vitro were carried out to detect its anti-tumor capacity. Results SEC3 expression of the vector is about 3 times of GV365-SEC3 vector, and ES expression is over 22.5-fold compared with GV365-ES vector. Moreover, OD490 value of CO group (1.212 ± 0.003) was notably lower than NC (negative control) group (1.124 ± 0.01) (P  Conclusion The successful construction of co-expressed vector lays the foundation for further studies in vivo. These promising results suggest a new strategy to treating cervical cancer.
