Molecular characterization of the porcine JHDM1A gene associated with average daily gain: evaluation its role in skeletal muscle development and growth.
Article in Molecular biology reports, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
JHDM1A, a member of the JHDM (JmjC-domain-containing histone demethylase) family, plays an central role in gene silencing, cell cycle, cell growth and cancer development through histone H3K36 demethylation modification. Here reported the cloning, expression, chromosomal location and association analysis with growth traits of porcine JHDM1A gene. Sequence analysis showed that the porcine JHDM1A gene encodes 1,162 amino acids and contains JmjC, F-box, and CXXC zinc-finger domains, which coding sequence and deduced protein shares 91 and 99% similarity with human JHDM1A, respectively. Spatio-Temporal expression analysis indicated that the mRNA expression of porcine JHDM1A had significantly higher levels in the middle (65 days) and later (90 days) period's embryo skeletal muscle than that of 33 days, and showed a ubiquitously expression but with the highest abundance in kidney, lung and liver of an adult pig. Radiation hybrid mapping and the following linkage mapping data indicate that JHDM1A maps to 2p17 region of pig chromosome 2 (SSC2). Allele frequency differences were detected in different pig breeds and an association study was performed with a SNP within 3'UTR. The results showed that there is a tendency for allele frequencies to differ between the fast growth breeds (Yorkshire) and slow growth pig breeds (Qingping pigs, Yushan Black pigs, Erhualian pigs and Dahuabai pigs). The association analysis using a Berkshire × Yorkshire F(2) population indicated that the C224G polymorphism had a highly significant association with average daily gain on test (P < 0.01), a trend association with average back fat thickness (P < 0.07), and significant associations (P < 0.01) on percent of average drip loss, Fiber Type II Ratio, muscle shear force and average lactate content in μmol/g. This study provides the first evidence that JHDM1A is differentially expressed in porcine embryonic skeletal muscle and associated with meat growth and quality traits.
