Abstract

The efficient delivery of antisense oligonucleotides (ASOs) to the targeted cells and organs remains a challenge, in particular, in vivo . Here, we investigated the ability of a library of biodegradable lipid nanoparticles (LNPs) in delivering ASO to both cultured human cells and animal models. We first identified three top-performing lipids through in vitro screening using GFP-expressing HEK293 cells. Next, we explored these three candidates for delivering ASO to target proprotein convertase subtilisin/kexin type 9 (PCSK9) mRNA in mice. We found that lipid 306-O12B-3 showed efficiency with the median effective dose (ED 50 ) as low as 0.034 mg·kg -1 , which is a notable improvement over the efficiency reported in the literature. No liver or kidney toxicity was observed with a dose up to 5 mg·kg -1 of this ASO/LNP formulation. The biodegradable LNPs are efficient and safe in the delivery of ASO and pave the way for clinical translation.

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

  • The 306-O12B-3 lipid formulation mainly delivered ASO into the liver and could not cross the blood-brain barrier through intravenous injection.

    “However, this lipid formulation mainly delivered the ASO into the liver and could not cross the BBB through intravenous injection.”

    From Neurotransmitter-derived lipidoids (NT-lipidoids) for enhanced brain delivery through intravenous injection (2020) · cites this paper as [30]

    The Results section, “Biodistribution of ASO-Loaded LNPs In Vivo” (page unavailable), reports that intravenously administered ASO/LNP complexes accumulated mainly in the liver, with 306-O12B-3 producing the strongest liver signal. The Methods section says the brain was among the organs examined, but the copy does not establish that this formulation could not cross the blood-brain barrier; predominant liver accumulation alone does not demonstrate that. (LLM, conf=0.86)

  • Lipidoid 306-O12B-3 can efficiently deliver ASO both in vitro and in vivo.

    “In a recent study, we identified lipidoid 306-O12B-3 that can efficiently deliver ASO both in vitro and in vivo (30).”

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.
