In vivo analysis of a fluorescent SUMO fusion in transgenic Drosophila.
Article in Fly, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Sumoylation, the covalent attachment of SUMO, a 90 amino acid peptide related to ubiquitin, is a major modulator of protein functions. Fluorescent SUMO protein fusions have been used in cell cultures to visualize SUMO in vivo but not in multicellular organisms. We generated a transgenic line of Drosophila expressing an mCherry-SUMO fusion. We analyzed its pattern in vivo in salivary gland nuclei expressing Venus-HP1 to recognize the different chromatin components (Chromocenter, chromosome IV). We compared it to SUMO immunostaining on squashed polytene chromosomes and observed similar patterns. In addition to the previously reported SUMO localizations (chromosome arms and chromocenter), we identify 2 intense binding sites: the fourth chromosome telomere and the DAPI-bright band in the region 81F.
