Abstract

Background: Although the transient nature of transgene expression using first‐generation adenovirus (Ad) vectors is well known, the exact mechanisms responsible for this phenomenon are uncertain. Methods: Rats were given intramuscular (i.m.) injections of a first‐generation Ad containing the human fibroblast growth factor 4 (hFGF‐4) gene driven by the cytomegalovirus (CMV) promoter and enhancer (CMV‐PE). The copy number of hFGF‐4 mRNA and viral DNA was measured in the same muscles by quantitative RT‐PCR and quantitative PCR at times between 1 h and 84 days after virus injection. Quantitative Southern blot analysis for the intact hFGF‐4 transcription unit DNA was also performed, and the methylation status of the CMV‐PE DNA in the muscle was determined using bisulfite sequencing. Results: The copy number of hFGF‐4 mRNA peaked at 6 h then decreased 56‐fold by 24 h, and a further 240‐fold between days 3 and 28. Although the viral DNA copy number also decreased 23‐fold between 6 h and 28 days, the ratio of copies of hFGF‐4 mRNA per copy of viral DNA decreased 385‐fold over this period. Methylation of the CMV‐PE DNA in the muscle at both CpG and non‐CpG sites was observed 24 h after virus administration and had increased at day 7. Conclusions: Decreased transcription associated with extensive methylation of the CMV‐PE was the major mechanism responsible for the decrease in transgene mRNA levels. Strategies for preventing transcriptional silencing will be valuable for improving the duration of transgene expression from adenoviral vectors. Copyright © 2004 John Wiley & Sons, Ltd.

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.
