Abstract

MOTIVATION: Prior biological knowledge greatly facilitates the meaningful interpretation of gene-expression data. Causal networks constructed from individual relationships curated from the literature are particularly suited for this task, since they create mechanistic hypotheses that explain the expression changes observed in datasets. RESULTS: We present and discuss a suite of algorithms and tools for inferring and scoring regulator networks upstream of gene-expression data based on a large-scale causal network derived from the Ingenuity Knowledge Base. We extend the method to predict downstream effects on biological functions and diseases and demonstrate the validity of our approach by applying it to example datasets. AVAILABILITY: The causal analytics tools 'Upstream Regulator Analysis', 'Mechanistic Networks', 'Causal Network Analysis' and 'Downstream Effects Analysis' are implemented and available within Ingenuity Pathway Analysis (IPA, http://www.ingenuity.com). SUPPLEMENTARY INFORMATION: Supplementary material is available at Bioinformatics online.

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

  • IPA identified BMP9 (or GDF2), MyD88, and mTOR as upstream small molecules to target the Hif1a regulon and XO4+ network.

    “IPA identified BMP9 (or GDF2), a ligand of the TGF-β superfamily, the Toll-like receptor (TLR) adaptor MyD88, and mTOR”

    From Transcriptional signature in microglia associated with Aβ plaque phagocytosis (2021) · cites this paper as [55]

    The Introduction and §3.3 describe IPA as a method for predicting upstream regulators from gene-expression data. But the paper’s examples in §5.1 and §5.3 do not report BMP9/GDF2, MyD88, or mTOR as regulators of a Hif1a regulon or XO4+ network. The source supports use of IPA for this kind of analysis, not the specific findings attributed to it. (LLM, conf=0.78)

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.
