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

purposeIn this study, the novel poly(diethylaminoethylmethacrylate) (PDEAEM)/Pluronic F127 pentablock copolymers were found to be able to mediate high-efficiency transfection of human epithelial ovarian carcinoma (SKOV3) cell line while showing significantly lower efficacy in human epithelial retinal (ARPE-19) cell line and Swiss Mouse Fibroblast (3T3) cell line.

methodsThe intracellular routes of polyplexes were investigated by confocal microscopy after appropriately labeling the polymer and DNA.

resultsIt was found that lesser nuclear entry in the ARPE-19 cells may result in the lower efficiency of transfection. Since the SKOV3 proliferation rate was found to be much higher than that of the ARPE-19 cells, the nuclear entry of polyplexes was assumed to be correlated with the proliferation rate, and it was hypothesized that the novel pentablock copolymers could mediate gene delivery selectively in fast growing cells. The different intracellular barriers to gene transfer may also account for the observed difference of transfection efficacy.

conclusionsAlthough the validity of the hypothesis that our pentablock copolymer could selectively transfect hyperproliferative cells needs further examination, this present work provides a new perspective to design targeting vectors for cancer therapies based on different characteristics among specific cell types.
