Endogenously imprinted genes in Drosophila melanogaster.
Article in Molecular genetics and genomics : MGG, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Genomic imprinting is an epigenetic state that results from differential processing of chromosomes during gametogenesis and which can cause differential expression of genes depending on the sex of the parent transmitting that gene. In Drosophila, many examples of imprinted marker genes have been documented and imprinting of these genes involves highly conserved epigenetic regulators. However, no endogenously imprinted genes have yet been identified. Here we present a phenotypic and transcriptional analysis of parthenogenetic (gynogenetic) and genotypically identical but sexually produced adult female Drosophila. We find that while parthenogenetic females have a superficially normal phenotype and are viable and fertile, their lifespan is extended relative to their sexually-produced counterparts. Microarray/transcriptional analysis of parthenogenetic versus sexually-produced females reveals 76 genes with consistently altered patterns of expression, 36 upregulated and 40 downregulated, some with known effects on aging. Analysis of individuals with uniparental inheritance of only portions of their genome suggest that many of these genes may be indirectly imprinted, responding to either other imprinted genes or redistribution of chromatin components that are differentially allocated to sex and autosomal heterochromatin in a sex-dependent manner during gametogenesis. As gene expression dependent on the parental origin of the genome meets the definition of genomic imprinting, our study provides evidence that endogenous genes are imprinted in Drosophila.
