Clarithromycin attenuates the expression of monocyte chemoattractant protein-1 by activating toll-like receptor 4 in human mesangial cells.
Article in Clinical and experimental nephrology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
backgroundSignaling pathways induced by the activation of renal toll-like receptor 4 (TLR4) play a pivotal role in chronic kidney disease (CKD). Some recent studies suggested that clarithromycin (CAM), a 14-membered ring macrolide, exerts renoprotective effects by suppressing proinflammatory chemokines. However, its beneficial effects on signaling pathways through renal TLR4 activation are unknown.
methodsCultured human mesangial cells (MCs) were treated with lipopolysaccharide (LPS). Expression of monocyte chemoattractant protein-1 (MCP-1/CCL2) and interleukin-8 (IL-8/CXCL8) was analyzed by quantitative RT-PCR and enzyme-linked immunosorbent assay. Signaling pathways affected by CAM were determined by examining the activation of nuclear factor-κB (NF-κB) and p38 mitogen-activated protein kinase (MAPK) by performing western blotting.
resultsCAM inhibited both the mRNA and protein expression of MCP-1 without cell injury but did not affect those expressions of IL-8 in LPS-stimulated MCs. Interestingly, CAM decreased p38 MAPK activation by inhibiting phosphorylation but did not affect NF-κB activation.
conclusionOur results indicated that CAM exerted renoprotective effects by suppression of p38 MAPK activity and by decreasing the expression of MCP-1 in LPS-stimulated MCs. Given the implication of TLR4 signaling in CKD, CAM may be a potential treatment of choice for CKD.
