A role of the Trx-G complex in Cid/CENP-A deposition at Drosophila melanogaster centromeres.
Article in Chromosoma, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Centromeres are epigenetically determined chromatin structures that specify the assembly site of the kinetochore, the multiprotein machinery that binds microtubules and mediates chromosome segregation during mitosis and meiosis. The centromeric protein A (CENP-A) and its Drosophila orthologue centromere identifier (Cid) are H3 histone variants that replace the canonical H3 histone in centromeric nucleosomes of eukaryotes. CENP-A/Cid is required for recruitment of other centromere and kinetochore proteins and its deficiency disrupts chromosome segregation. Despite the many components that are known to cooperate in centromere function, the complete network of factors involved in CENP-A recruitment remains to be defined. In Drosophila, the Trx-G proteins localize along the heterochromatin with specific patterns and some of them localize to the centromeres of all chromosomes. Here, we show that the Trx, Ash1, and CBP proteins are required for the correct chromosome segregation and that Ash1 and CBP mediate for Cid/CENP-A recruitment at centromeres through post-translational histone modifications. We found that centromeric H3 histone is consistently acetylated in K27 by CBP and that nej and ash1 silencing respectively causes a decrease in H3K27 acetylation and H3K4 methylation along with an impairment of Cid loading.
