[Construction of recombinant adenovirus containing full-length sense and antisense cyclin B1 cDNA and their impact on proliferation and apoptosis of HeLa cells].

Objective To construct a recombinant adenovirus vector carrying the full-length sense and antisense cyclin B1 cDNA of human,and to investigate the influence of the recombinant adenoviruses on the cultured human cervical carcinoma cell line HeLa. Methods The recombinant adenovirus vectors were constructed by homologous recombination technique. The recombinant adenoviruses were packaged and amplified in 293A cells. Then the recombinant adenoviruses were used to infect HeLa cells. The influence was determined by cell counting and flow cytometry. Results The HeLa cells infected with antisense recombinant adenovirus exhibited significant cell apoptosis and growth inhibition compared to the normal HeLa cells and the cells infected with sense recombinant adenovirus. Conclusion Recombinant adenoviruses vectors containing the full-length sense and antisense cDNA of human cyclin B1 is successfully constructed,which has laid a foundation for further studies on its anticancer functions.
