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

Aurora B kinase forms the enzymatic core of the Chromosomal Passenger Complex (CPC) and is a master regulator of mitosis. Understanding the regulation of Aurora B is critical to illuminate its role in mitosis. INCENP, Survivin and Borealin have all been known to promote Aurora B activation. In this study, we have identified the Aurora A activator protein TPX2 as a novel scaffold and co-activator protein of the CPC. Studies utilizing M-phase Xenopus egg extracts (XEE) revealed that the immunodepletion of endogenous TPX2 from XEE decreases Aurora B-Survivin and Aurora B-INCENP interactions, leading to a consequent reduction in Aurora B activity. Further, residues 138 to 328 of Xenopus TPX2 (TPX2 B) are sufficient to enhance Aurora B-Survivin association and Aurora B kinase activity in vitro. Importantly, experiments with pancreatic cancer cell lines suggest that this mechanism of Aurora B activation by TPX2 is likely to be conserved in human cells. Strikingly, the overexpression of human TPX2 B in HeLa cells causes defects in metaphase chromosome alignment and INCENP localization. Thus, in addition to its already established role as an Aurora A activator, our data support the role of TPX2 as a novel co-activator of Aurora kinase B.
