Depletion of a single nucleoporin, Nup107, prevents the assembly of a subset of nucleoporins into the nuclear pore complex.

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
The nuclear pore complex (NPC) is a protein assembly that contains several distinct subcomplexes. The mammalian nucleoporin (Nup)-107 is part of a hetero-oligomeric complex, that also contains Nup160, Nup133, Nup96, and the mammalian homolog of yeast Sec13p. We used transfection of HeLa cells with small interfering RNAs to specifically deplete mRNA for Nup107. In a domino effect, Nup107 depletion caused codepletion of a subset of other Nups on their protein but not on their mRNA level. Among the affected Nups was a member of the Nup107 subcomplex, Nup133, whereas two other tested members of this complex, Nup96 and Sec13, were unaffected and assembled into Nup107Nup133-deficient NPCs. We also tested several phenylalanine-glycine repeat-containing Nups that serve as docking sites for karyopherins. Some of these, such as Nup358, Nup214 on the cytoplasmic, and Nup153 on the nucleoplasmic side of the NPC, failed to assemble into Nup107Nup133-depleted NPCs, whereas p62, a Nup at the center of the NPC, was unaffected. Interestingly, the filamentous, NPC-associated protein Tpr also failed to assemble into the NPCs of Nup107-depleted cells. These data indicate that Nup107 functions as a keystone Nup that is required for the assembly of a subset of Nups into the NPC. Despite the depletion of Nup107 and the accompanying effects on other Nups, there was no significant effect on the growth rate of these cells and only a partial inhibition of mRNA export. These data indicate redundancy of Nups in the function of the mammalian NPC.
