Nuclear translocation of RanGAP1 coincides with virtual nuclear envelope breakdown in fission yeast meiosis.
Article in Communicative & integrative biology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
In higher eukaryotes, mitosis proceeds with nuclear envelope breakdown (NEBD) and disassembly of the nuclear pore complex (NPC); this is designated "open" mitosis. On the other hand, in many fungi, mitosis and chromosome segregation takes place without NEBD; this is designated "closed" mitosis. In a recent study on Schizosaccharomyces pombe, a closed mitosis organism, we reported a novel phenomenon that is equivalent to NEBD: a mixing of nuclear proteins and cytoplasmic proteins occurred transiently for a few minutes in meiosis without physical breakdown of the nuclear envelope. We designated this event virtual nuclear envelope breakdown (V-NEBD). In S. pombe, nuclear translocation of Rna1, a RanGAP1 homolog in S. pombe, occurs during meiosis, and this translocation of Rna1 leads to collapse of the Ran-GTP gradient across the nuclear envelope and occurs coincidently with V-NEBD. Here, we describe possible roles of RanGAP1 in V-NEBD in S. pombe and provide insights into the roles V-NEBD may play in meiosis.
