Ageratina adenophora damages the rumen epithelium via inducing the expression of inflammatory factors in goats.
Article in Journal of animal science, 2024. 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
The aim of this experiment was to investigate the effects of Ageratina adenophora on the expression of epithelium tight junction proteins and inflammatory factors in the rumen of goats. Twelve goats were randomly divided into three groups. The first group was the blank control group (n = 3, C) which was fed normal diet. The second group was fistulas control group (n = 3, RFC), which was fitted with rumen fistulas, and fed normal diet. The third group was the A. adenophora test group (n = 6, AA), which was fitted with rumen fistulas and fed a mixture of 60% of normal diet and 40% of A. adenophora grass powder. The feeding experiment lasted for 90 d, after which all goats were sacrificed and samples were collected from the rumen dorsal sac and ventral sac. The relative expression of mRNA of inflammatory factors in the rumen epithelium (tumor necrosis factor alpha [TNF-α], interferon gamma [IFN-γ], interleukin 1 beta [IL-1β], IL-2, IL-4, IL-6, and IL-10) and tight junction protein genes (occludin, claudin-1, and ZO-1) was measured by quantitative real-time fluorescence PCR. Expression of tight junction proteins in the rumen epithelium was measured by Western blot. A correlation was established between the expression of inflammatory factors and tight junction protein genes using Graph Pad Prism. The results showed that A. adenophora caused a significant increase in the mRNA expression levels of TNF-α, IFN-γ, IL-1β, IL-2, IL-6, and IL-10 in the rumen epithelial (P < 0.05 or P < 0.01). The expression of tight junction proteins at both gene and protein levels was significantly decreased (P < 0.05 or P < 0.01). Furthermore, the correlation analysis revealed that the changes in tight junction protein expression in the test group were closely related to the upregulation of the expression of inflammatory factors TNF-α and IFN-γ in rumen epithelial cells. In conclusion, the expression of inflammatory factors was increased and the expression of tight junction proteins was decreased in goats after feeding on A. adenophora, which caused some damage to the rumen epithelium.
