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

Dynein is a minus-end-directed microtubule motor important for mitotic spindle positioning. In budding yeast, dynein activity is restricted to anaphase when the nucleus enters the bud neck, yet the nature of the underlying regulatory mechanism is not known. Here, the microtubule-associated protein She1p is identified as a novel regulator of dynein activity. In she1 Delta cells, dynein is activated throughout the cell cycle, resulting in aberrant spindle movements that misposition the spindle. We also found that dynactin, a cofactor essential for dynein motor function, is a dynamic complex whose recruitment to astral microtubules (aMTs) increases dramatically during anaphase. Interestingly, loss of She1p eliminates the cell-cycle regulation of dynactin recruitment and permits enhanced dynactin accumulation on aMTs throughout the cell cycle. Furthermore, localization of the dynactin complex to aMTs requires dynein, suggesting that dynactin is recruited to aMTs via interaction with dynein and not the microtubule itself. Lastly, we present evidence supporting the existence of an incomplete dynactin subcomplex localized at the SPB, and a complete complex that is loaded onto aMTs from the cytoplasm. We propose that She1p restricts dynein-dependent spindle positioning to anaphase by inhibiting the association of dynein with the complete dynactin complex.
