Abstract

Sialic acids are key glycans that are involved in many different normal cellular functions, as well as being receptors for many pathogens. However, Sia come in diverse chemically modified forms. Here, we examined and manipulated the expression of 7,9- O - and 9- O -acetyl modified Sia on cells commonly used in influenza virus and other research by engineering the enzymes that produce or remove the acetyl groups.

Claims other papers make about this one

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

  • Human alveolar carcinoma A549 cells are secretory cells and produce substantial amounts of mucin.

    “In contrast, human alveolar carcinoma A549 cells are secretory cells and produce substantial amounts of mucin (Barnard et al., 2019;Berger et al., 1999).”

    From Mechanism of Virus Attenuation by Codon Pair Deoptimization (2020) · cites this paper as Barnard et al., 2019

  • MDCK cells produce only a relatively thin layer of mucus.

    “MDCK cells only produce a relatively thin layer of mucus (Barnard et al., 2019;Harush-Frenkel et al., 2008).”

    From Mechanism of Virus Attenuation by Codon Pair Deoptimization (2020) · cites this paper as Barnard et al., 2019

    The Results section identifies A549 cells as secretory and reports their mucin secretion, but does not describe mucus production by MDCK cells. Searches for MDCK mucus, mucin, and a thin mucus layer found no passage establishing the claim in our copy; page numbers were not available. (LLM, conf=0.75)

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.
