Abstract

Hepatic steatosis is a multifactorial condition that is often observed in obese patients and is a prelude to non-alcoholic fatty liver disease. Here, we combine shotgun sequencing of fecal metagenomes with molecular phenomics (hepatic transcriptome and plasma and urine metabolomes) in two well-characterized cohorts of morbidly obese women recruited to the FLORINASH study. We reveal molecular networks linking the gut microbiome and the host phenome to hepatic steatosis. Patients with steatosis have low microbial gene richness and increased genetic potential for the processing of dietary lipids and endotoxin biosynthesis (notably from Proteobacteria), hepatic inflammation and dysregulation of aromatic and branched-chain amino acid metabolism. We demonstrated that fecal microbiota transplants and chronic treatment with phenylacetic acid, a microbial product of aromatic amino acid metabolism, successfully trigger steatosis and branched-chain amino acid metabolism. Molecular phenomic signatures were predictive (area under the curve = 87%) and consistent with the gut microbiome having an effect on the steatosis phenome (>75% shared variation) and, therefore, actionable via microbiome-based therapies. Metabolic activity of specific human gut microorganisms contributes to liver steatosis in obese women.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • PIEZO1 positively correlated with genes encoding collagens such as COL1A1, COL3A1, and COL6A1 in human liver transcription profiling datasets.

    “We found that PIEZO1 positively correlated with genes encoding collagens such as COL1A1, COL3A1, and COL6A1 (Fig. 1, A to C) (15).”
  • Multi-faceted studies using different methods and research platforms can enable more mechanistic understandings of associations between microbes and host phenotypes.

    “An additional advantage of multi-faceted studies using different methods and research platforms is that they can enable more mechanistic understandings of associations between microbes and host phenotypes 37-39 .”

  • Studies in cohorts of morbidly obese women confirmed the increase in Gram-negative proteobacteria and linked steatosis occurrence with alterations in aromatic and branched-chain amino acid metabolism.

    “Studies performed in cohorts of morbidly obese women confirmed the increased in Gram- proteobacteria and linked, for the first time, steatosis occurrence with alterations in aromatic and branched-chain amino acid metabolism [233].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
