Abstract

Zeroing in on essential human genes: More powerful genetic techniques are helping to define the list of genes required for the life of a human cell. Two papers used the CRISPR genome editing system and a gene trap method in haploid human cells to screen for essential genes (see the Perspective by Boone and Andrews). Wang et al. 's analysis of multiple cell lines indicates that it may be possible to find tumor-specific dependencies on particular genes. Blomen et al. investigate the phenomenon in which nonessential genes are required for fitness in the absence of another gene. Hence, complexity rather than robustness is the human strategy.

  • Pooled CRISPR screening is a powerful and widely used method for identifying genes involved in biological mechanisms such as cell proliferation, drug resistance, and viral infection.

    “Pooled CRISPR screening is a powerful and widely used method for identifying genes involved in biological mechanisms such as cell proliferation 1, 2 , drug resistance 3 , and viral infection 4 .”
  • Joung, J.'s team employed the SHERLOCK technique to detect SARS-CoV-2 viral RNA using the CRISPR-Cas13a system.

    “Joung, J.'s team employed the SHERLOCK technique to detect SARS-CoV-2 viral RNA using the CRISPR-Cas13a system.”

    From A Review of Research on CRISPR/Cas9 Gene Editing Technology in Disease Treatment (2024) · cites this paper as [17]

    The paper’s Abstract describes CRISPR-Cas9 and gene-trap screens for essential genes in human cells. Searches for Joung, SHERLOCK, SARS-CoV-2, Cas13a, and viral RNA detection found no passage addressing the claimed diagnostic technique. (LLM, conf=0.78)

    Experimental — accuracy not yet measured
  • This assay is highly sensitive and specific, capable of detecting low concentrations of SARS-CoV-2 RNA in a short period of time.

    “This assay is highly sensitive and specific, capable of detecting low concentrations of SARS-CoV-2 RNA in a short period of time [17].”

    From A Review of Research on CRISPR/Cas9 Gene Editing Technology in Disease Treatment (2024) · cites this paper as [17]

    The paper’s indexed Abstract describes CRISPR and gene-trap screens for genes essential to human cancer-cell survival, not a viral RNA detection assay. Searches for SARS-CoV-2 RNA and for rapid, sensitive diagnostic detection found no passage addressing the assay’s sensitivity, specificity, detection limit, or speed. No page number is provided for the indexed passages. (LLM, conf=0.78)

    Experimental — accuracy not yet measured
  • Many identified mediator complex components were concordantly associated with resistance to other targeted cancer therapies, but were also controversially identified as essential genes in CML cells.

    “Many of the identified mediator complex components were concordantly associated with resistance to other targeted cancer therapies,44,45 but were also controversially identified as essential genes in CML cells.46”

    From Integrated drug profiling and CRISPR screening identify BCR::ABL1-independent vulnerabilities in chronic myeloid leukemia (2024) · cites this paper as [46]

    The passage labeled Abstract (page unavailable) reports screens in CML cell lines and identifies CML-essential genes, but it does not identify Mediator complex components among them. Searches for “Mediator complex” and MED subunit names found no passage in our copy establishing the specific claim attributed to citation 46; the resistance-to-therapy clause is attached to citations 44 and 45, not this source. (LLM, conf=0.72)

    Experimental — accuracy not yet measured
  • Gene-level enrichment scores were highly correlated with a previous genome-wide CRISPR screen in K562 cells (r = 0.85).

    “we computed gene-level enrichment scores (Supplementary Fig. 4e, Supplementary Table 3), which were highly correlated with a previous genome-wide CRISPR screen in K562 cells10 (r = 0.85)”

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.
