1 · What the graph read from 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.

2 · The registry

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 measurement of nitric oxide in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells is used as a model for evaluating the anti-inflammatory or chemopreventive potential of substances. Thienodolin, isolated from a Streptomyces sp. derived from Chilean marine sediment, inhibited nitric oxide production in LPS-stimulated RAW 264.7 cells (IC50 = 17.2 +/- 1.2 microM). At both the mRNA and protein levels, inducible nitric oxide synthase (iNOS) was suppressed in a dose-dependent manner. Mitogen-activated protein kinases (MAPKs), one major upstream signaling pathway involved in the transcription of iNOS, were not affected by treatment of thienodolin. However, the compound blocked the degradation of IkappaBa resulting in inhibition of NF-kappaB p65 nuclear translocation, and inhibited the phosphorylation of signal transducers and activators of transcription 1 (STAT1) at Tyr701. This study supports further exploration of thienodolin as a potential therapeutic agent with a unique mechanistic activity.
