Gene transfection efficiency and destination of recombinant adenovirus gene transfer through internal jugular vein injection in rats / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To investigate the adenovirus-mediated LacZ gene expression and the destination in different organs of SD rats after the intravenous injection in rats.@*METHODS@#Recombinant adenovirus vector containing LacZ was transferred to SD rats by injecting into the internal jugular vein. To identify the sites and periods of LacZ gene expression, X-gal staining was used to detect beta-gal level and period of LacZ gene expression of different organs in the transfected and non-transfected rats at different time intervals.@*RESULTS@#On the 1st day after the injection, the lung, liver, kidney, and spleen expressed some beta-gal; on the 3rd day after the injection, the lung, liver, kidney, and spleen expressed beta-gal obviously; their peak levels were on the 7th day; the beta-gal level decreased on the 14th day; beta-gal expression disappeared in the most organs except the lungs on the 28th day. In all animals, the brain did not express any beta-gal.@*CONCLUSION@#The adenovirus-mediated exogenous gene transfer in the internal jugular vein may be an effective approach of gene therapy in some diseases in the lung, liver, and kidney.
