The Effect of Repeat Administration of Lipoplexes on Gene Delivery, Biodistribution, and Cytokine Response in Immunocompetent Tumor-Bearing Mice.
Article in Journal of pharmaceutical sciences, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
It is becoming increasingly clear that the intravenous administration of nanoparticles elicits an immune response that compromises delivery efficiency and can be life threatening. This study investigated both the systemic and tissue-level cytokine response to repeat administration of lipoplexes coated with either lactose or PEG. We report that blood cytokine levels differ significantly from that observed in individual tissues. While we consistently observed a reduced cytokine response to lactosylated particles, this did not result in enhanced delivery or expression as compared to PEGylated formulations. We also document that repeat injection did not increase plasmid levels in the liver, lung, or spleen, but delivery to the tumor was enhanced under these conditions. In addition, we show that changes in neither blood nor tissue cytokines correlated strongly with reporter gene expression, and we observed relatively constant expression efficiencies (RLU/ng plasmid) across all tissues despite a considerably reduced cytokine response in the tumor. Together, these results indicate that both biodistribution and cytokine responses are dramatically altered by a repeat intravenous injection of lipoplexes, and that the mechanisms regulating reporter gene expression are not straightforward.
