Acetylation of Nup62 by TIP60 ensures accurate chromosome segregation in mitosis.

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.
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
Stable transmission of genetic information during cell division requires faithful mitotic spindle assembly and chromosome segregation. In eukaryotic cells, nuclear envelope breakdown (NEBD) is required for proper chromosome segregation. Although a list of mitotic kinases has been implicated in NEBD, how they coordinate their activity to dissolve the nuclear envelope and protein machinery such as nuclear pore complexes was unclear. Here, we identified a regulatory mechanism in which Nup62 is acetylated by TIP60 in human cell division. Nup62 is a novel substrate of TIP60, and the acetylation of Lys432 by TIP60 dissolves nucleoporin Nup62-Nup58-Nup54 complex during entry into mitosis. Importantly, this acetylation-elicited remodeling of nucleoporin complex promotes the distribution of Nup62 to the mitotic spindle, which is indispensable for orchestrating correct spindle orientation. Moreover, suppression of Nup62 perturbs accurate chromosome segregation during mitosis. These results establish a previously uncharacterized regulatory mechanism in which TIP60-elicited nucleoporin dynamics promotes chromosome segregation in mitosis.
