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 segregation of genetic material during mitosis is coordinated by the mitotic spindle, whose action depends upon the polarity patterns of its microtubules (MTs). Homotetrameric mitotic kinesin-5 motors can crosslink and slide adjacent spindle MTs, but it is unknown whether they or other motors contribute to establishing these MT polarity patterns. Here, we explored whether the Drosophila embryo kinesin-5 KLP61F, which plausibly crosslinks both parallel and antiparallel MTs, displays a preference for parallel or antiparallel MT orientation. In motility assays, KLP61F was observed to crosslink and slide adjacent MTs, as predicted. Remarkably, KLP61F displayed a 3-fold higher preference for crosslinking MTs in the antiparallel orientation. This polarity preference was observed in the presence of ADP or ATP plus AMPPNP, but not AMPPNP alone, which induces instantaneous rigor binding. Also, a purified motorless tetramer containing the C-terminal tail domains displayed an antiparallel orientation preference, confirming that motor activity is not required. The results suggest that, during morphogenesis of the Drosophila embryo mitotic spindle, KLP61F's crosslinking and sliding activities could facilitate the gradual accumulation of KLP61F within antiparallel interpolar MTs at the equator, where the motor could generate force to drive poleward flux and pole-pole separation.
