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 NIMA protein kinase of Aspergillus nidulans is required for the G2/M transition of the cell cycle. Mutants lacking NIMA arrest without morphological characteristics of mitosis, but they do contain an activated p37nimX kinase (the Aspergillus homologue of p34cdc2). To gain a better understanding of NIMA function we have investigated the effects of expressing various NIMA constructs in Aspergillus, fission yeast and human cells. Our experiments have shown that the instability of the NIMA protein requires sequences in the non-catalytic C-terminus of the protein. Removal of this domain results in a stable protein that, once accumulated, promotes a lethal premature condensation of chromatin without any other aspects of mitosis. Similar effects were also observed in fission yeast and human cells accumulating Aspergillus NIMA. This phenotype is independent of cell cycle progression and does not require p34cdc2 kinase activity. As gain of NIMA function by accumulation results in premature chromatin condensation, and loss of NIMA function results in an inability to enter mitosis, we propose that NIMA functions in G2 to promote the condensation of chromatin normally associated with entry into mitosis.
