Abstract

Current viral vectors for gene therapy are associated with serious safety concerns, including leukemogenesis, and nonviral vectors are limited by low gene transfer efficiency. Here we investigate the therapeutic utility of chemically modified mRNA as an alternative to DNA-based gene therapy. A combination of nucleotide modifications abrogates mRNA interaction with Toll-like receptor (TLR)3, TLR7, TLR8 and retinoid-inducible gene I (RIG-I), resulting in low immunogenicity and higher stability in mice. A single intramuscular injection of modified murine erythropoietin mRNA raises the average hematocrit in mice from 51.5% to 64.2% after 28 days. In a mouse model of a lethal congenital lung disease caused by a lack of surfactant protein B (SP-B), twice weekly local application of an aerosol of modified SP-B mRNA to the lung restored 71% of the wild-type SP-B expression, and treated mice survived until the predetermined end of the study after 28 days.

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.
