Identification and characteristics of a novel gene, EJO1, in the Chinese mitten crab (Eriocheir japonica sinensis) ovary.

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
EJO1, a novel gene presumably involved in the ovary development of the Chinese mitten crab (Eriocheir japonica sinensis), was identified and characterized by suppression subtractive hybridization and cDNA macroarray analysis. EJO1 expression was 2.6-fold higher at stage III than at stage II during the ovary development of the mitten crab. EJO1 is 876 bp in length containing a 759 bp open reading frame which encodes a 252-amino-acid protein. Homology analysis showed that no sequence significantly matching EJO1 was found in SwissProt, so it was deduced as a novel gene (GenBank accession number: AY185917). The EJO1 protein is probably a secretion protein with a signal peptide of 17 amino acids. The pI/Mw deduced from the amino acid sequence was 6.18/28.18 kDa. Expression profile showed that EJO1 mRNA is highly expressed in the heart, intestine, and ovary of the crab, while there is little or no expression in muscle and hepatopancreas. The differential expression of EJO1 at the different developmental stages of the ovary was further confirmed by Northern blot analysis. In conclusion, EJO1 is a novel gene differentially expressed in the ovary of the Chinese mitten crab, which may play an important role in the ovary development.
