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

The matrix (M) protein of vesicular stomatitis virus (VSV) has been found to promote assembly and budding of virions as well as down-regulating of VSV transcription. Large quantities of M protein can be produced in insect cells infected with recombinant baculovirus expressing the VSV M gene under control of the polyhedrin promoter. Analysis by pulse-chase experiments and density gradient centrifugation revealed that the [35S]methionine-labeled M protein synthesized in insect cells is released into the extracellular medium in association with lipid vesicles (liposomes). Electron microscopy and immunogold labeling showed that M protein expressed in insect cells induced the formation on plasma membrane of vesicles containing M protein, which are released from the cell surface in the form of liposomes. The baculovirus vector itself or recombinants expressing VSV glycoprotein (G) or nucleocapsid (N) protein did not produce the formation of vesicles in infected cells. The baculovirus-expressed M protein retains biological activity as demonstrated by its capacity to inhibit transcription when reconstituted with VSV nucleocapsids in vitro. These data suggest that M protein has the capacity to associate with the plasma membrane of infected cells and, in so doing, causes evagination of the membrane to form a vesicle which is released from the cell. This observation leads to the postulate, which requires further proof, that the VSV M protein can induce the formation and budding of liposomes from the cell membrane surface.
