OBJECTIVEThe recombinant adenovirus vector carrying p14ARF gene was constructed for using in the interference therapy in signal transduction of laryngeal squamous cell carcinoma.

METHODSThe total cDNA fragment of p14ARF was cloned into the shuttle plasmid pAdTrack-CMV, with the resultant plasmid and the backbone plasmid pAdEasy-1, the homologous recombination took place in the E.Coli BJ5183 and the recombinant adenoviral plasmid was generated. The adenoviruses were packaged and amplified in the 293 cells. Then the viral titer was checked by GFP.

RESULTSThe recombinant adenovirus vector carrying p14ARF was constructed successfully. The viral titer was 2.3 x 10(9).

CONCLUSIONThe recombinant adenovirus vector could introduce p14ARF gene into the laryngeal squamous cell carcinoma line or tumor tissue effectively, which would provide experimental basis for the mechanisms and further study of the interference therapy in signal transduction of laryngeal squamous cell carcinoma.
