A fluorescent splice-switching mouse model enables high-throughput, sensitive quantification of antisense oligonucleotide delivery and activity.
Article in Cell reports methods, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
While antisense oligonucleotides (ASOs) are used in the clinic, therapeutic development is hindered by the inability to assay ASO delivery and activity in vivo. Accordingly, we developed a dual-fluorescence, knockin mouse model that constitutively expresses mKate2 and an engineered EGFP that is alternatively spliced in the presence of ASO to induce expression. We first examined free ASO activity in the brain following intracerebroventricular injection revealing EGFP splice-switching is both ASO concentration and time dependent in major central nervous system cell types. We then assayed the impact of lipid nanoparticle delivery on ASO activity after intravenous administration. Robust EGFP fluorescence was observed in the liver and EGFP+ cells were successfully isolated using fluorescence-activated cell sorting. Together, these results show the utility of this animal model in quantifying both cell-type- and organ-specific ASO delivery, which can be used to advance ASO therapeutics for many disease indications.
