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

Polymer architecture can influence biodistribution and the mode of presentation of bioactive agents to cells. Herein delivery, loading efficiency, and mode of cellular entry of polymer conjugates of the photosensitizer Meso-Tetra (4-Carboxyphenyl) Porphyrine (MTCP) are examined when attached to hyperbranched amine terminated poly(amido amine) (PAMAM) dendrimer or random coil linear N-(2-hydroxypropyl)methacrylamide (HPMA) copolymer containing free amines in the side chains. The in vitro dark cytotoxicity and phototoxicity of MTCP and related conjugates are assessed on mouth epidermal carcinoma (KB) and human adenocarcinoma alveolar basal epithelial (A549) cells. Phototoxicity of polymeric conjugates increases by ≈100 and 4000 fold in KB and A549 cells compared with nonconjugated MTCP. The increase in phototoxicity activity is shown to result from increased rate of cellular uptake, whereas, cellular internalization of MTCP is negligible in comparison with the conjugated forms. The results of this study suggest the superiority of amine-terminated HPMA copolymer versus PAMAM dendrimer under study for delivery of MTCP. Treatment with various pharmacological inhibitors of endocytosis shows that polymer architecture influences the mechanism of cellular uptake of the conjugated photosensitizer. Results show that polymeric conjugates of MTCP improve solubility, influence the route and the rate of cellular internalization, and drastically enhance the uptake of the photosensitizer.
