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, we chose three of the flavonoids isorhamnetin-3-O-rutinoside(IRR) diosmetin-7-O-beta-D-xylopyranosyl-(1-6)-beta-D-glucopyranoside(DXG) and morin, which showed obvious efflux, to test the hypothesis that a specific efflux transporter is responsible for their transportation.

methodsThe intestinal epithelial membrane transport of the flavonoids were examined using the monolayer of the human Caco-2 cell line grown in Transwells, a common model of intestinal absorption. The flavonoids were measured by high performance liquid chromatography with UV detector.

resultThe efflux of morin, IRR and DXG, across Caco-2 cell monolayers was examined over the concentration range from 2 to 200 microM and showed a saturable process. The depletion of the cellular ATP stores with 5 mM iodoacetamide led to a significant inhibition of the efflux. Fifty micromolar verapamil, a chemical inhibitor of P-glycoprotein, had no effect on the transport of the three flavonoids, while the presence of 50 microM MK-571 and 1 mM probenecid, MRP inhibitors, resulted in an obvious reduction in the efflux. Moreover, inhibition of morin transport by MK-571 demonstrated concentration dependence. The transportation of the three flavonoids was compared with apigenin.

conclusionThese data support a role for MRPs in the intestinal transcellular efflux of morin, IRR, DXG and possibly other hydrophilic flavonoid aglycons and glycosides.
