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

Mitotic spindle assembly requires the combined activity of various molecular motor proteins, including Eg5 and dynein. Together, these motors generate antagonistic forces during mammalian bipolar spindle assembly; what remains unknown, however, is how these motors are functionally coordinated such that antagonism is possible. Given that Eg5 generates an outward force by crosslinking and sliding apart antiparallel microtubules (MTs), we explored the possibility that dynein generates an inward force by likewise sliding antiparallel MTs. We reasoned that antiparallel overlap, and therefore the magnitude of a dynein-mediated force, would be inversely proportional to the initial distance between centrosomes. To capitalize on this relationship, we utilized a nocodazole washout assay to mimic spindle assembly. We found that Eg5 inhibition led to either monopolar or bipolar spindle formation, depending on whether centrosomes were initially separated by less than or greater than 5.5 microm, respectively. Mathematical modeling predicted this same spindle bistability in the absence of functional Eg5 and required dynein acting on antiparallel MTs to do so. Our results suggest that dynein functionally coordinates with Eg5 by crosslinking and sliding antiparallel MTs, a novel role for dynein within the framework of spindle assembly.
