Abstract

Although gene transfer with adeno-associated virus (AAV) vectors has typically been low, transduction can be enhanced in the presence of adenovirus gene products through the formation of double stranded, non-integrated AAV genomes. We describe the unexpected finding of high level and stable transgene expression in mice following intramuscular injection of purified recombinant AAV (rAAV). The rAAV genome is efficiently incorporated into nuclei of differentiated muscle fibers where it persists as head-to-tail concatamers. Fluorescent in situ hybridization of muscle tissue suggests single integration sites. Neutralizing antibody against AAV capsid proteins does not prevent readministration of vector. Remarkably, no humoral or cellular immune responses are elicited to the neoantigenic transgene product E. coli beta-galactosidase. The favorable biology of rAAV in muscle-directed gene therapy described in this study expands the potential of this vector for the treatment of inherited and acquired diseases.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • After AAV enters a mammalian cell, its DNA persists long-term in the nucleus as episomes, which are less likely than genomic integration to cause oncogenic transformation.

    “Upon transduction of a target mammalian cell, the single-stranded AAV DNA undergoes second strand synthesis and subsequently persists long-term within the host nucleus in the form of monomeric or concatemeric episomes [Afione 1996, Fisher 1997]. Compared with integration into the host genome, episomes are associated with minimal risk of causing oncogenic transformation.”

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.
