Abstract

While the catalog of mammalian transcripts and their expression levels in different cell types and disease states is rapidly expanding, our understanding of transcript function lags behind. We present a robust technology enabling systematic investigation of the cellular consequences of repressing or inducing individual transcripts. We identify rules for specific targeting of transcriptional repressors (CRISPRi), typically achieving 90%-99% knockdown with minimal off-target effects, and activators (CRISPRa) to endogenous genes via endonuclease-deficient Cas9. Together they enable modulation of gene expression over a ∼1,000-fold range. Using these rules, we construct genome-scale CRISPRi and CRISPRa libraries, each of which we validate with two pooled screens. Growth-based screens identify essential genes, tumor suppressors, and regulators of differentiation. Screens for sensitivity to a cholera-diphtheria toxin provide broad insights into the mechanisms of pathogen entry, retrotranslocation and toxicity. Our results establish CRISPRi and CRISPRa as powerful tools that provide rich and complementary information for mapping complex pathways.

  • Compared with gain-of-function perturbations, a higher proportion of loss-of-function perturbations yield phenotypes in growth and chemical-genetic screens, especially for members of protein complexes.

    “Compared with gain-of-function perturbations, a higher proportion of loss-of-function perturbations yield phenotypes in growth and chemical-genetic screens, especially for members of protein complexes (Gilbert et al., 2014; Horlbeck et al., 2016).”

    From Mapping information-rich genotype-phenotype landscapes with genome-scale Perturb-seq (2022) · cites this paper as Gilbert et al., 2014

    In Results, “A Genome-Scale CRISPRa Screening Platform” reports that fewer CRISPRa sgRNAs than CRISPRi sgRNAs caused growth phenotypes. The ricin-screen Results likewise report phenotypes for all genes selected for a prior knockdown phenotype, but only a subset upon activation. The toxin-screen Results identify protein-complex members as CRISPRi hits, but do not establish that loss-of-function perturbations yield a higher proportion of hits than gain-of-function perturbations in chemical-genetic screens, especially for those members.

  • CRISPRi and CRISPRa technologies utilize catalytically inactive Cas9 (dCas9) fused to either a transcriptional repressor (e.g., KRAB) or a transcriptional activator (e.g., VPR).

    “For example, CRISPRi (interference)23–25 and CRISPRa (activation)26–30 technologies utilize catalytically inactive Cas9 (dCas9) fused to either a transcriptional repressor (e.g., KRAB, Krüppel associated box) or a transcriptional activator (e.g., VPR, VP64-p65-Rta).”

    From Large-scale CRISPR screening in primary human 3D gastric organoids enables comprehensive dissection of gene-drug interactions (2025) · cites this paper as [28]

    The Introduction describes dCas9 fusion proteins used to repress transcription (CRISPRi) or activate it (CRISPRa), and the CRISPRi Results identify KRAB as a repressor domain. The CRISPRa Results describe a sunCas9 system that recruits activating effector domains, but do not identify VPR (VP64-p65-Rta) as its activator or describe a dCas9–VPR fusion. No page numbers are available in our copy. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Alternatives to DNA cleavage-induced editing include base editing, prime editing, and CRISPRi/CRISPRa.

    “Alternatives to DNA cleavage-induced editing include using CRISPR-Cas9 for direct chemical sequence alteration (base editing) 25,26 , providing RNA templates for gene alteration (prime editing) 27,28 , and for transcriptional control (CRISPR interference, CRISPRi; CRISPR activation, CRISPRa) 29,30 (Fig. 3).”

  • Pooling gene perturbations increases scalability but cannot be combined with imaging of complex or dynamic cellular phenotypes.

    “Pooling gene perturbations greatly improves scalability, but is not compatible with imaging of complex and dynamic cellular phenotypes.”

  • Mutations in ubiquitously expressed trafficking factors or aminoacyl-tRNA synthetases can cause neurodegenerative diseases such as Charcot-Marie-Tooth disease.

    “Striking examples are familial mutations causing neurodegenerative diseases, such as hereditary motor and sensory neuropathies (Charcot-Marie-Tooth disease), which can be caused by mutations in ubiquitously expressed trafficking factors (RAB7A, DNM2, DYNC1H1), or aminoacyl-tRNA synthetases (AARS, GARS, HARS, MARS)2.”

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.
