Comparative quantitative analysis of gene expression profiles of glycoside hydrolase family 10 xylanases in the sheep rumen during a feeding cycle.
Article in Applied and environmental microbiology, 2013. 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
Xylanase is a crucial hydrolytic enzyme that degrades plant polysaccharides in the rumen. To date, there is no information on the genetic composition and expression characteristics of ruminal xylanase during feeding cycles of ruminants. Here, the major xylanase of the glycoside hydrolase family 10 (GH 10) from the rumen of small-tail Han sheep was investigated during a feeding cycle. We identified 44 distinct GH 10 xylanase gene fragments at both the genomic and transcriptional levels. Comparison of their relative abundance showed that results from the evaluation of functional genes at the transcriptional level are more reliable indicators for understanding fluctuations in xylanase levels. The expression patterns of six xylanase genes, detected at all time points of the feeding cycle, were investigated; we observed a complex trend of gene expression over 24 h, revealing the dynamic expression of xylanases in the rumen. Further correlation analysis indicated that the rumen is a dynamic ecosystem where the transcript profiles of xylanase genes are closely related to ruminal conditions, especially rumen pH and bacterial population. Given the huge diversity and changing composition of enzymes over the entire rumen, this research provides valuable information for understanding the role of functional genes in the digestion of plant material.
