Systemic Delivery of Modified mRNA Encoding Herpes Simplex Virus 1 Thymidine Kinase for Targeted Cancer Gene Therapy
Open accessAbstract
Failure of clinical trials of nonviral vector-mediated gene therapy arises primarily from either an insufficient transgene expression level or immunostimulation concerns caused by the genetic information carrier (e.g., bacteria-generated, double-stranded DNA (dsDNA)). Neither of these issues could be addressed through engineering-sophisticated gene delivery vehicles. Therefore, we propose a systemic delivery of chemically modified messenger RNA (mRNA) as an alternative to plasmid DNA (pDNA) in cancer gene therapy. Modified mRNA evaded recognition by the innate immune system and was less immunostimulating than dsDNA or regular mRNA. Moreover, the cytoplasmic delivery of mRNA circumvented the nuclear envelope, which resulted in a higher gene expression level. When formulated in the nanoparticle formulation liposome-protamine-RNA (LPR), modified mRNA showed increased nuclease tolerance and was more effectively taken up by tumor cells after systemic administration. The use of LPR resulted in a substantial increase of the gene expression level compared with the equivalent pDNA in the human lung cancer NCI-H460 carcinoma. In a therapeutic model, when modified mRNA encoding herpes simplex virus 1-thymidine kinase (HSV1-tk) was systemically delivered to H460 xenograft-bearing nude mice, it was significantly more effective in suppressing tumor growth than pDNA.

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.
