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

Detection of a repellent factor, such as a semaphorin (Sema), causes localized collapse of the growth cone and directs the neurite away from the repellent. Growth cone collapse results from concomitant cytoskeletal rearrangements and detachment of adhesion sites from the extracellular matrix, via mostly unknown signaling mechanisms. In cultures of dorsal root ganglion neurons, we found that Sema3A treatment stimulates the synthesis of the eicosanoid, 12(S)-hydroxyeicosatetraenoic acid (HETE), whereas Sema3A-induced growth cone collapse is prevented when 12(S)-HETE synthesis is blocked with an inhibitor of 12/15-lipoxygenase (LO). Exogenously applied product of 12/15-LO, 12(S)-HETE, mimics Sema3A-induced collapse. As observed by interference reflection and confocal microscopy, 12(S)-HETE causes the loss of growth cone adhesion sites. The adhesion site effect seems partially independent of the actin cytoskeleton because growth cones treated with Sema3A and 12/15-LO inhibitor remain spread despite actin cytoskeleton loss. These studies demonstrate that 12/15-LO activity is a necessary step in Sema3A collapse signaling in growth cones and suggest a mechanism for its action.
