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

Actin assembly on the surface of Listeria monocytogenes in the cytoplasm of infected cells provides a model to study actin-based motility and changes in cell shape. We have shown previously that the ActA protein, exposed on the bacterial surface, is required for polarized nucleation of actin filaments. To investigate whether plasma membrane-associated ActA can control the organization of microfilaments and cell shape, variants of ActA, in which the bacterial membrane signal had been replaced by a plasma membrane anchor sequence, were produced in mammalian cells. While both cytoplasmic and membrane-bound forms of ActA increased the F-actin content, only membrane-associated ActA caused the formation of plasma membrane extensions. This finding suggests that ActA acts as an actin filament nucleator and shows that permanent association with the inner face of the plasma membrane is required for changes in cell shape. Based on the observation that the amino-terminal segment of ActA and the remaining portion which includes the proline-rich repeats cause distinct phenotypic modifications in transfected cells, we propose a model in which two functional domains of ActA cooperate in the nucleation and dynamic turnover of actin filaments. The present approach is a new model system to dissect the mechanism of action of ActA and to further investigate interactions of the plasma membrane and the actin cytoskeleton during dynamic changes of cell shape.
