Epigenetic marks for chromosome imprinting during spermatogenesis in coccids.
Article in Chromosoma, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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
The establishment of sex-specific epigenetic marks during gametogenesis is one of the key feature of genomic imprinting. By immunocytological analysis, we thoroughly characterized the chromatin remodeling events that take place during gametogenesis in the mealybug Planococcus citri, in which an entire haploid set of (imprinted) chromosomes undergoes facultative heterochromatinization in male embryos. Building on our previous work, we have investigated the interplay of several epigenetic marks in the regulation of this genome-wide phenomenon. We characterized the germline patterns of histone modifications, Me(3)K9H3, Me(2)K9H3, and Me(3)K20H4, and of heterochromatic proteins, PCHET2 (HP1-like) and HP2-like during male and female gametogenesis. We found that at all stages in oogenesis chromatin is devoid of any detectable epigenetic marks. On the other hand, spermatogenesis is accompanied by a complex pattern of redistribution of epigenetic marks from euchromatin to heterochromatin, and vice versa. At the end of spermatogenesis, sperm heads are decorated by all the molecules we tested, except for PCHET2. However, only Me(3)K9H3 and Me(2)K9H3 are still detectable in the male pronucleus. We suggest that the histone H3 lysine 9 methylation is the signal used to establish the male-specific imprinting on the paternal genome, thus allowing it to be distinguished from the maternal genome in the developing embryo.
