Elementary research of the formation mechanism of sex-related fluorescent cocoon of silkworm, Bombyx mori.
Article in Molecular biology reports, 2012. 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
To understand mechanisms for the difference of uptaking and transporting the pigments between the male and female in the silkworm, Bombyx mori strain of sex-related fluorescent cocoon, the fluorescent pigments in the midgut lumen, midgut, blood, silk glands and cocoon were analyzed with thin-layer chromatography, and showed that fluorescent colors of cocoons consisted with that of blood and silk glands. The different fluorescent colors of cocoons between the male and female may be mainly caused by the difference of accumulation and transportation for fluorescent pigments in the midgut and in the silk glands. Furthermore the midgut proteins were separated with Native-PAGE, and the proteins respectively recovered from three fluorescent regions presenting on a Native-PAGE gel for the female silkworms were determined using shotgun proteomics and mass spectrometry sequencing, of which 60, 40 and 18 proteins respectively from the region 1, 2 and 3 were identified. It was found that the several kinds of low molecular mass 30 kDa lipoproteins and the actins could be detected in all three regions, troponin, 30 kDa lipoprotein and 27 kDa glycoprotein precursor could be detected in the region 2 and 3, suggesting these proteins may be fluorescent pigments binding candidates proteins. Analysis of gene ontology indicated that the identified proteins in the three regions linked to the cellular component, molecular function, and biological process categories. These results provide a new clew to understand the formation mechanism of sex-related fluorescent cocoon of silkworm.
