Abstract

The development of new treatments in the post-genomic era requires methods for safe delivery of foreign genetic information in vivo. As a transient, natural and controllable alternative to recombinant viruses or plasmid DNA (pDNA), purified or in vitro transcribed messenger RNA (mRNA) can be used for the expression of any therapeutic protein in vitro and in vivo. As it has been shown previously, the simple injection of naked mRNA results in local uptake and expression. We show here that this process, in the skin, can greatly be modulated according to the injection solution composition and blocked by an excess of competing nucleic acids or a drug affecting cytosolic mobility. Different cell types at the site of injection can take up the foreign nucleic acid molecules and the protein translated from this is detected for no more than a few days. To test this gene transfer method in humans, we produced in vitro transcribed mRNA under good manufacturing practice (GMP) conditions in a dedicated facility. After injection into the human dermis, we could document the translation of the exogenous mRNA. Our results pave the way toward the use of mRNA as a vehicle for transient gene delivery in humans.

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.
