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

Background: The kynurenine pathway (KP) plays a major role in neuroinflammation by converting the amino acid tryptophan into a variety of neuroactive products, including neurotoxic quinolinic acid (QUIN). The gene expression regulatory role of microRNAs in neuroinflammation is well documented; however, their impact on KP in the brain remains unexplored. Methods: In this study, we investigated whether the neuroimmune miR-132/212 cluster regulates one or more members of the KP during lipopolysaccharide (LPS)-induced neuroinflammation Results: In wildtype mice, we demonstrated that a subtoxic dose of LPS triggers a significant neuroinflammatory response with upregulation of KP enzymes, particularly kynurenine 3-monooxygenase (KMO), a key enzyme in QUIN synthesis, leading to elevated brain levels of this neurotoxic metabolite. Interestingly, KMO expression and activity remained elevated in miR-132/212 knockout mice after post-inflammation resolution. Conclusion: Collectively, these findings suggest that the miR-132/212 cluster functions as a novel modulator of KP metabolism during LPS-induced inflammation, and acts as a potential therapeutic target for controlling neurotoxic QUIN accumulation in neuroinflammatory conditions.
