6'-Sialylactose abolished lipopolysaccharide-induced inflammation and hyper-permeability in endothelial cells.
Article in Archives of pharmacal research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Disruption of the endothelial barrier function and reduction in cell migration leads to endothelial dysfunction. One of the most abundant human milk oligosaccharides, 6'-sialylactose (6'-SL), is reported to exert various biological functions related to inflammatory responses. In this study, we evaluated the effects of 6'-SL on lipopolysaccharide (LPS)-induced inflammation caused by endothelial barrier damage. Our results showed that LPS at 500 ng/mL strongly not only abolished cell migration but also hyperactivated MAPK and NF-κB pathways. 6'-SL suppressed LPS-induced endothelial inflammation via ERK1/2, p38, and JNK MAPK pathways. 6'-SL supported endothelial junctions by upregulating PECAM-1 expression and mRNA levels of tight junctions, such as ZO-1 and occludin, which were downregulated by LPS stimulation. It significantly inhibited the nuclear translocation of NF-κB, along with the downregulation of inflammatory cytokines, including TNF-α, IL-1β, MCP-1, VCAM-1, and ICAM-1. Furthermore, 6'-SL abolished NF-κB-mediated STAT3 in controlling endothelial migration and hyperpermeability via downregulating STAT3 activation and nuclear translocation. Finally, LPS induced over-expression of VCAM-1 and ZO-1 disassembly in both atheroprone and atheroprotective areas of mouse aorta, which were reversed by 6'-SL treatment. Altogether, our findings suggest that 6'-SL is a potent therapeutic agent for modulating inflammatory responses and endothelial hyperpermeability.
