SCENIC: single-cell regulatory network inference and clustering

2017

Objective: Simultaneous gene regulatory network reconstruction and cell-state identification from single-cell RNA-seq data.

Why it works: The abstract states that cis-regulatory analysis can guide identification of transcription factors and cell states, and the web research summary describes a decomposition into network inference, motif-based pruning, and regulon activity scoring.

Stages

  1. 1.
    Network inference(broad_screen)

    The web research summary states that SCENIC first uses GENIE3 or GRNBoost for co-expression or network inference.

    Selection: co-expression or network inference from single-cell RNA-seq data

  2. 2.
    Motif-enrichment-based pruning to direct targets or regulons(secondary_characterization)

    The web research summary states that RcisTarget is used for motif-enrichment-based pruning to direct targets or regulons after network inference.

    Selection: motif enrichment and direct-target pruning

  3. 3.
    Per-cell regulon activity scoring(functional_characterization)

    The web research summary states that AUCell is used for per-cell regulon activity scoring in the final stage of SCENIC.

    Selection: regulon activity scoring across individual cells

Steps

  1. 1.
    Infer co-expression or regulatory network candidates from single-cell RNA-seq datanetwork inference component

    Generate candidate regulatory relationships from expression data.

    This step occurs first because downstream motif-based pruning and regulon scoring require an initial set of candidate regulatory relationships.

  2. 2.
    Prune inferred relationships using motif enrichment to identify direct targets or regulonsmotif-enrichment and pruning component

    Refine candidate regulatory relationships toward direct targets and regulons.

    This step follows network inference because motif-based pruning acts on the initially inferred candidate relationships.

  3. 3.
    Score regulon activity in individual cellsregulon activity scoring component

    Quantify regulon activity per cell to support cell-state identification.

    This step occurs after regulon definition because per-cell activity scoring requires the regulons produced by the pruning stage.
