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

objectiveObesity is associated with an increase in various pro-inflammatory and anti-inflammatory cytokines, but the interplay of these cytokines is incompletely understood. We conducted experiments to test a broader hypothesis that a dynamic interplay of pro-inflammatory and anti-inflammatory cytokines controls lipid storage in adipocytes.

designThree experiments were designed to test the overall hypothesis that proinflammatory cytokine (for example, tumor necrosis factor-α (TNF-α) inhibits anti-inflammatory cytokine (for example, adiponectin) activity in an attempt to limit excess lipid accumulation in adipocytes.

resultsExperiment one showed that in pro-inflammatory animal models (ap2-P65, ob/ob and high-fat diet-induced obese mice), the increase in TNF-α expression was associated with a decrease in adiponectin expression. Experiment two showed that in 3T3-L1 adipocytes, TNF-α significantly reduced lipid accumulation and glucose uptake induced by adiponectin, and increased lipolysis. Experiment three showed that in 3T3-L1 adipocytes, TNF-α reduced mRNA and protein expression of adiponectin. Adiponectin gene transcription and mRNA stability were both reduced by TNF-α. The expression of peroxisome proliferator-activated receptor gamma, an activator of adiponectin gene promoter, was reduced by TNF-α. The inhibitory activity of TNF-α was blocked by the chemical inhibitors of NF-κB and super suppressor IκBα.

conclusionsTNF-α opposes the action of adiponectin in the regulation of lipid metabolism, and inhibits adiponectin expression at transcriptional and post-transcriptional levels. The results suggest that pro-inflammatory cytokine inhibit anti-inflammatory cytokine in adipocytes to reduce lipid storage. This suggests a potential role of anti-inflammatory cytokines in the control of adipose tissue expansion.
