1 · What the graph read from it

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.

2 · The registry

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

Cell-penetrating peptides (CPP) are received a lot of attention as an intracellular delivery tool for hydrophilic molecules such as drugs, proteins, and DNAs. We designed and synthesized nona-arginine analogues 1-5 [FAM-β-Ala-(l-Arg-l-Arg-l-Pro)3-(Gly)3-NH2 (1), FAM-β-Ala-(l-Arg-l-Arg-l-Pro(NH2))3-(Gly)3-NH2 (2), FAM-β-Ala-(l-Arg-l-Arg-l-Pro(Gu))3-(Gly)3-NH2 (3), FAM-β-Ala-(l-Arg)2-(l-Pro(Gu))2-(l-Arg)4-l-Pro(Gu)-(Gly)3-NH2 (4), and FAM-β-Ala-(l-Arg)6-(l-Pro(Gu))3-(Gly)3-NH2 (5)] containing l-proline (l-Pro) or cationic proline derivatives (l-Pro(NH2) and l-Pro(Gu)), and investigated their cell-penetrating abilities. Interestingly, only peptide 3 having the side-chain guanidinyl l-Pro(Gu) exhibited a secondary structural change in cellular environment. Specifically, peptide 3 formed a random structure in hydrophilic conditions, whereas it formed a helical structure under amphipathic conditions. Furthermore, during cellular permeability tests, peptide 3 demonstrated greater cell-penetrating activity than other peptides and effectively transported plasmid DNA into HeLa cells. Thus, l-Pro(Gu)-containing peptide 3 may be a useful candidate as a gene delivery carrier.
