Efficient protection and transfection of small interfering RNA by cationic shell-crosslinked knedel-like nanoparticles.
Article in Nucleic acid therapeutics, 2013. 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
Despite the great potential of small interfering RNA (siRNA) as a therapeutic agent, progress in this area has been hampered by a lack of efficient biocompatible transfection agents. Recently, cationic shell-crosslinked knedel-like nanoparticles (cSCKs) were found to possess lower cytotoxicity and better transfection ability for phosphorothioate ODNs and plasmid DNA than the commonly used cationic lipid-based agent Lipofectamine. To determine the usefulness of cSCKs for siRNA transfection, a small library of cSCKs with varying percentage of primary and tertiary amines was assessed for its ability to bind to siRNA, inhibit siRNA degradation in human serum, and to transfect HeLa and mouse macrophage cell lines. The silencing efficiency in HeLa cells was greatest with the cSCK with 100% primary amines (pa100) as determined by their viability following transfection with cytotoxic and non-cytotoxic siRNAs. cSCK-pa100 showed greater silencing efficiency than Lipofectamine 2000 in the HeLa cells, as well in 293T and human bronchial epithelial (HEK) cells, but was comparable in human bronchial epithelial (BEAS-2B) cells and human mammary epithelial (MCF10a) cells. cSCK-pa100 also showed greater silencing of iNOS expression than Lipofectamine 2000 in a mouse macrophage cell line, and provided greater protection from serum degradation, demonstrating its potential usefulness as an siRNA transfection agent. The siRNA silencing of iNOS at lower concentrations of siRNA could be enhanced by complexation with the fusogenic GALA peptide, which was shown to enhance endosomal escape following uptake.
