Nuclear membrane vesicle targeting to chromatin in a Drosophila embryo cell-free system.
Article in Molecular biology of the cell, 1997. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
A Drosophila cell-free system was used to characterize proteins that are required for targeting vesicles to chromatin and for fusion of vesicles to form nuclear envelopes. Treatment of vesicles with 1 M NaCl abolished their ability to bind to chromatin. Binding of salt-treated vesicles to chromatin could be restored by adding the dialyzed salt extract. Lamin Dm is one of the peripheral proteins whose activity was required, since supplying interphase lamin isoforms Dm1, and Dm2 to the assembly extract restored binding. As opposed to the findings in Xenopus, okadaic acid had no effect on vesicle binding. Trypsin digestion of the salt-stripped vesicles eliminated their association with chromatin even in the presence of the dialyzed salt extract. One vesicles attached to chromatin surface, fusion events took place were found to be sensitive to guanosine 5'-[gamma-thio]triphosphate (GTP gamma S). These chromatin-attached vesicles contained lamin Dm and otefin but not gp210. Thus, these results show that in Drosophila there are two populations of nuclear vesicles. The population that interacts first with chromatin contains lamin and otefin and requires both peripheral and integral membrane proteins, whereas fusion of vesicles requires GTPase activity.
