Abstract

Seminal yeast studies have established the value of comprehensively mapping genetic interactions (GIs) for inferring gene function. Efforts in human cells using focused gene sets underscore the utility of this approach, but the feasibility of generating large-scale, diverse human GI maps remains unresolved. We developed a CRISPR interference platform for large-scale quantitative mapping of human GIs. We systematically perturbed 222,784 gene pairs in two cancer cell lines. The resultant maps cluster functionally related genes, assigning function to poorly characterized genes, including TMEM261, a new electron transport chain component. Individual GIs pinpoint unexpected relationships between pathways, exemplified by a specific cholesterol biosynthesis intermediate whose accumulation induces deoxynucleotide depletion, causing replicative DNA damage and a synthetic-lethal interaction with the ATR/9-1-1 DNA repair pathway. Our map provides a broad resource, establishes GI maps as a high-resolution tool for dissecting gene function, and serves as a blueprint for mapping the genetic landscape of human cells.

  • Direct capture Perturb-seq can be used to study genetic interactions between cholesterol biosynthesis and DNA repair genes.

    “we next explored the use of direct capture Perturb-seq to study genetic interactions, specifically a complex set of GIs we recently identified between genes that control cholesterol biosynthesis (e.g. FDPS, MVD, and IDI1) and genes that facilitate DNA repair (e.g. ATR and genes encoding components of the 9–1-1 complex)28.”
  • An earlier model held that repressing cholesterol biosynthesis causes toxic intermediates to accumulate, producing replication stress and arrest after genotoxin exposure.

    “We previously proposed a model for GIs between cholesterol biosynthesis and DNA repair genes wherein repression of the former leads to the buildup of toxic metabolic intermediates in cells, which then cause replicative stress and genotoxin-activated cell cycle arrest28.”
  • In the data, rates of novel sgRNA pairs varied from 0.09 to 0.15 across experiments, roughly consistent with a previous report.

    “In our data, we observed rates of novel pairs varying from 0.09–0.15 across experiments, which is roughly consistent with a previous report28.”
  • Functionally related genes interact similarly, making the genetic interaction manifold highly constrained and enabling imputation strategies.

    “We and others have established that functionally related genes interact similarly—in geometric terms the GI manifold is therefore highly constrained, enabling imputation strategies (1, 2, 7, 12, 29).”
  • Primary human cell types such as skin fibroblasts or blood cells can be reprogrammed into iPSCs by transient expression of four transcription factors, including the Yamanaka factors.

    “Primary cell types readily obtained from human adult donors, such as skin fibroblasts or peripheral blood cells, can be reprogrammed to become induced pluripotent stem cells (iPSCs) by the transient expression of four transcription factors, such as the so-called “Yamanaka factors”89,90”

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.
