Abstract:
Objective: To prepare an adenovirus, Ad-CD, expressing bacterial cytosine deaminase(CD),and use it for tumor suicide gene therapy. Methods: We constructed a recomb ined adenoviral vector carrying CD or LacZ. 293 packaging cell was trans fected by the newly-constructed plasmid and generated the infectious virus. The n the adenovirus was used to infect C26 cell in vitro. Results: The growth of Ad-CD-infected cell was obviously surpressed after admini stration of 5-FC. Conclusion: CD gene carried by adenoviral vec tor is effective for tumor cell suicide gene therapy in vitro.
