Assessment of Recombinant Adenoviral Vectors for Hepatic Gene Therapy

Abstract

Recombinant adenoviral vectors have recently been used to transfer genes into a number of different cell types in vitro and in vivo. A recombinant adenoviral vector bearing the Escherichia coli β-galactosidase (β-gal) gene was used to quantitate the frequency of hepatocyte transduction in the mouse after direct viral infusion into the portal vein. When 1010 adenoviral particles were infused, over 95% of the hepatocytes were transduced in vivo as determined by x-gal staining. The transduction protocol is relatively safe in that there is no detectable helper virus production in transduced animals and that very few extrahepatic cells are transduced by this method. There is also no evidence of significant liver pathology unless substantially greater quantities of virus are used. However, the transduced hepatocytes do not appear to persist in vivo because the percentage of hepatocytes expressing β-gal declined over time. Four months after the procedure, 0.5–10% of the hepatocytes contain detectable β-gal activity in vivo. The change in β-gal-positive cells correlates with decreasing amounts of adenoviral DNA. Thus, current recombinant adenoviral vectors may have clinical applications in gene therapy for acute hepatic disorders. This study demonstrates that the recombinant adenovirus can be used to transfer genes into greater than 95% of mouse hepatocytes in vivo. The expression from the majority of transduced hepatocytes is slowly lost over a 3- to 4-month period. This vector system has the advantage of being a very efficient means of gene transfer into the liver; the disadvantage of the system relates to the transient nature of expression in most of the transduced hepatocytes. Further experimentation will be required to determine whether a significant number of transduced hepatocytes will remain indefintely.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
