Squamosamide derivative FLZ inhibits TNF-α-induced ICAM-1 expression via down-regulation of the NF-κB signaling pathway in ARPE-19 cells.

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
Dysfunction of the retinal pigment epithelium (RPE) resulting from chronic inflammation is implicated in the pathogenesis of age-related macular degeneration (AMD). It has been reported that tumor necrosis factor-α (TNF-α) could induce intercellular adhesion molecule-1 (ICAM-1) expression in RPE cells. FLZ, a novel synthetic squamosamide derivative from a Chinese herb, Annona glabra, has displayed significant anti-inflammatory activity. However, the effects of FLZ on TNF-α-induced ICAM-1 expression in RPE cells remain unknown. Therefore, in the present study, we evaluated the effects of FLZ on TNF-α-induced ICAM-1 expression in RPE cells. We found that FLZ prevented TNF-α-induced ICAM-1 expression and the ability of monocytes to adhere to ARPE-19 cells induced by TNF-α. Furthermore, FLZ inhibited TNF-α-induced NF-κB p65 expression, as well as phosphorylation of IκBα in ARPE-19 cells. Taken together, these results suggest that FLZ inhibited TNF-α-induced ICAM-1 expression through blocking NF-κB signaling pathway in ARPE-19 cells. Thus, FLZ could be used for designing novel therapeutic agents against AMD.
