Abstract

Key Points: Crbn I391V mice degrade known thalidomide derivative targets and recapitulate thalidomide-induced cytopenias and teratogenicity. Degradation of Ck1α is sufficient to explain the in vivo therapeutic window of lenalidomide in del(5q) myelodysplastic syndrome.

  • Mice harboring a homozygous CRBN I391V knock-in allele show increased miscarriage upon IMiD treatment compared with control mice, but do not exhibit IMiD-induced embryopathies resembling the human phenotype.

    “In line with these findings, mice harboring a homozygous CRBN I391V knock-in allele, despite exhibiting degradation of mmIKZF1/3, mmZFP91, and mmCSNK1A1 Fink et al., 2018, show increased miscarriage upon IMiD treatment compared with control mice; however, they do not exhibit IMiD-induced embryopathies resembling the human phenotype Fink et al., 2018 .”

    The ‘Thalidomide-induced fetal loss in Crbn I391V mice’ section (page unavailable) reports high fetal loss after lenalidomide or thalidomide treatment in homozygous knock-in mice, with no effect in wild-type mice. It says surviving litters generally appeared normal, but notes a trend toward increased anophthalmia—a malformation seen in human thalidomide embryopathy. That qualification makes the claim that the mice do not exhibit human-like embryopathies too absolute. (LLM, conf=0.86)

  • Position V388 corresponds to position 391 in mouse Crbn, which features the critical isoleucine variant responsible for the lack of IMiD activity in mouse cells, masking thalidomide teratogenicity.

    “Intriguingly, this site corresponds to position 391 in mouse Crbn, which features the critical isoleucine variant that is responsible for the lack of IMiD activity in mouse cells, hence masking the teratogenicity of thalidomide39.”

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.
