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

Augmented glycolysis due to metabolic reprogramming in lung myofibroblasts is critical to their profibrotic phenotype. The primary glycolysis byproduct, lactate, is also secreted into the extracellular milieu, together with which myofibroblasts and macrophages form a spatially restricted site usually described as fibrotic niche. Therefore, we hypothesized that myofibroblast glycolysis might have a non-cell autonomous effect through lactate regulating the pathogenic phenotype of alveolar macrophages. Here, we demonstrated that there was a markedly increased lactate in the conditioned media of TGF-β1 (transforming growth factor-β1)-induced lung myofibroblasts and in the BAL fluids (BALFs) from mice with TGF-β1- or bleomycin-induced lung fibrosis. Importantly, the media and BALFs promoted profibrotic mediator expression in macrophages. Mechanistically, lactate induced histone lactylation in the promoters of the profibrotic genes in macrophages, consistent with the upregulation of this epigenetic modification in these cells in the fibrotic lungs. The lactate inductions of the histone lactylation and profibrotic gene expression were mediated by p300, as evidenced by their diminished concentrations in p300-knockdown macrophages. Collectively, our study establishes that in addition to protein, lipid, and nucleic acid molecules, a metabolite can also mediate intercellular regulations in the setting of lung fibrosis. Our findings shed new light on the mechanism underlying the key contribution of myofibroblast glycolysis to the pathogenesis of lung fibrosis.
