Abstract

The direct intramuscular delivery of naked plasmid DNA has been demonstrated to allow expression of encoded heterologous genes in the target myocytes. The method has been employed to elicit immunization based upon delivery of antigen encoding plasmid DNA. For application in the context of achieving anti-tumor immunization against antigenic transforming oncoproteins, delivery of plasmid DNAs encoding these molecules would create significant potential safety hazards. As an alternative to DNA polynucleotide vectors, we explored the utility of mRNA vehicles for inducing foreign gene expression in muscle cells in vivo. Synthetic reporter-gene encoding mRNA transcripts were derived for this analysis. The Sindbis virus vector was also used to derive luciferase mRNA transcripts which possessed self-replication capacity. In these studies, it could be shown that the replicative vector was capable of directing significantly elevated levels of reporter gene expression in myocytes compared to a non-replicative mRNA species. In addition, the replicative species was capable of achieving significantly prolonged levels of in vivo gene expression compared to non-replicative mRNA. Both of these characteristics will make replicative mRNA vectors of utility for polynucleotide-based immunization protocols.

  • Injection of naked mRNA or self-amplifying RNA in vivo induces gene expression and generates immune responses, with self-amplifying RNA being more efficient for gene expression in situ.

    “Injection of naked mRNA or self-amplifying RNA in vivo induces gene expression and generates immune responses (4, 11-13), with self-amplifying RNA being more efficient for gene expression in situ (13,14).”

    From Nonviral delivery of self-amplifying RNA vaccines (2012) · cites this paper as [13]

    The in vivo gene-expression results report that injected replicative mRNA produced substantially more luciferase than non-replicative mRNA in muscle. The Discussion reports an immune response from prior CEA mRNA injections, but this study did not establish that its self-amplifying RNA generated an immune response; it discusses that possibility as a hypothesis (page not provided). (LLM, conf=0.87)

  • The shorter duration of expression in situ after RNA immunization compared with pDNA may be related to the induction of apoptosis of the transfected cell, which could occur during RNA amplification, leading to transient gene expression.

    “The shorter duration of expression in situ after RNA immunization compared with pDNA may be related to the induction of apoptosis of the transfected cell, which could occur during RNA amplification, leading to transient gene expression (12,13).”

    From Nonviral delivery of self-amplifying RNA vaccines (2012) · cites this paper as [13]

    The in vivo results report that replicative mRNA expression returned to baseline within 28 days, while plasmid DNA expression remained above baseline (Augmented gene expression in vivo). The Discussion proposes host-cell protein-synthesis inhibition and resulting cytopathogenicity as one possible explanation for the decline in mRNA-directed expression. It does not specifically identify apoptosis or establish that it occurs during RNA amplification. (LLM, conf=0.85)

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.
