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

We have used an in vitro assay to follow the proteins transferred from a donor to an acceptor upon fusion of early endosomes. The acceptor was a purified early endosomal fraction immunoisolated on beads and the donor was a metabolically-labeled early endosomal fraction in suspension. In the assay, both fractions were mixed in the presence of unlabeled cytosol, and then the beads were retrieved and washed. The donor proteins transferred to the acceptor were identified by two-dimensional gel electrophoresis and autoradiography. Approximately 50 major proteins were transferred and this transfer fulfilled all criteria established for endosome fusion in vitro. However, only a small subset of proteins was efficiently transferred, if donor endosomes were briefly sonicated to generate small (0.1 micron diam) vesicles before the assay. These include two acidic membrane proteins, and three alkaline peripheral proteins exposed on the cytoplasmic face of the membrane. Partial sequencing and Western blotting indicated that one of the latter components is annexin II, a protein known to mediate membrane-membrane interactions. Immunogold labeling of cryosections confirmed that annexin II is present on early endosomes in vivo. These data demonstrate that annexin II, together with the other four proteins we have identified, is a major component of fusogenic endosomal vesicles, suggesting that these proteins are involved in the binding and/or fusion process.
