Abstract

Drug With a (Re)Purpose: Thalidomide, once infamous for its deleterious effects on fetal development, has re-emerged as a drug of great interest because of its beneficial immunomodulatory effects. A derivative drug called lenalidomide significantly extends the survival of patients with multiple myeloma, but the molecular mechanisms underlying its efficacy remain unclear (see the Perspective by Stewart ). Building on a previous observation that thalidomide binds to cereblon, a ubiquitin ligase, Lu et al. (p. 305 , published online 28 November) and Krönke et al. (p. 301 , published online 28 November) show that in the presence of lenalidomide, cereblon selectively targets two B cell transcription factors (Ikaros family members, IKZF1 and IKZF3) for degradation. In myeloma cell lines and patient cells, down-regulation of IKZF1 and IKZF3 was necessary and sufficient for the drug's anticancer activity. Thus, lenalidomide may act, at least in part, by “grepurposing” a ubiquitin ligase.

  • Thalidomide analogues bring zinc-finger transcription factors and other targets to CRBN, the substrate receptor of the CRL4CRBN E3 ligase.

    “Thalidomide analogues recruit zinc-finger transcription factors and other targets to CRBN8–11, the substrate receptor of the cullin-RING E3 ubiquitin ligase CUL4A/B-RBX1-DDB1-CRBN (CRL4CRBN)12.”

    From The CDK inhibitor CR8 acts as a molecular glue degrader that depletes cyclin K (2020) · cites this paper as [9]

    The paper reports that lenalidomide increases binding of the zinc-finger transcription factors IKZF1 and IKZF3 to CRBN, which it identifies as a CRL4 substrate receptor (Abstract; page unavailable). It does not establish recruitment of other targets: it says alternative substrates may mediate other effects. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Thalidomide, lenalidomide, and pomalidomide cause ubiquitination and proteasomal degradation of IKZF1 and IKZF3 by bringing a C2H2 zinc finger domain to CRBN, the substrate receptor of CRL4CRBN.

    “The small molecules thalidomide, lenalidomide, and pomalidomide induce the ubiquitination and proteasomal degradation of the transcription factors Ikaros (IKZF1) and Aiolos (IKZF3) by recruiting a Cys2-His2 (C2H2) zinc finger domain to Cereblon (CRBN), the substrate receptor of the CRL4CRBN E3 ubiquitin ligase.”

    From Defining the human C2H2 zinc finger degrome targeted by thalidomide analogs through CRBN (2018) · cites this paper as [3]

    The indexed text (section labelled Abstract; page unavailable) shows that lenalidomide recruits IKZF1 and IKZF3 to CRBN through a region within zinc finger domain 2, promoting their ubiquitination and degradation. It also reports that thalidomide and pomalidomide decrease both proteins’ abundance, but does not establish that those two drugs use the same zinc-finger recruitment and ubiquitination mechanism. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Thalidomide analogs bind CRBN and change its substrate selectivity so that it recruits, ubiquitinates, and degrades proteins including IKZF1, IKZF3, CK1α, and GSPT1.

    “Thalidomide analogs bind Cereblon (CRBN), the substrate receptor of the CUL4-RBX1-DDB1-CRBN (CRL4CRBN) E3 ubiquitin ligase and alter its substrate selectivity to recruit, ubiquitinate and degrade seemingly unrelated proteins including Ikaros (IKZF1), Aiolos (IKZF3), Casein kinase 1 alpha (CK1α) and GSPT1 (2–7).”

    From Defining the human C2H2 zinc finger degrome targeted by thalidomide analogs through CRBN (2018) · cites this paper as [3]

    The paper’s Abstract reports that lenalidomide binds the CRBN-containing ligase complex and promotes recruitment, ubiquitination, and degradation of IKZF1 and IKZF3. It does not identify CK1α or GSPT1 as targets, so it supports only part of the cited sentence. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • Proteome-wide mass spectrometry showed selective degradation of endogenous IKZF1/3 and ZFP91 in multiple cell lines.

    “proteome-wide mass-spectrometry demonstrated selective degradation of endogenous IKZF1/3, and ZFP91 in multiple cell lines (3, 4, 16).”

    From Defining the human C2H2 zinc finger degrome targeted by thalidomide analogs through CRBN (2018) · cites this paper as [3]

    The copy’s Abstract (page not provided) reports SILAC-based mass spectrometry showing reduced IKZF1 and IKZF3 abundance in the MM1S cell line. It separately reports decreased endogenous IKZF1 and IKZF3 in cell lines, but does not report proteome-wide mass spectrometry across multiple cell lines or degradation of ZFP91. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Thalidomide, lenalidomide, and pomalidomide mediate CRL4CRBN-dependent degradation of more proteins than previously appreciated through a C2H2 ZF degron.

    “Thalidomide, lenalidomide and pomalidomide mediate CRL4CRBN-dependent degradation of a larger number of proteins than previously appreciated through a C2H2 ZF degron (3, 4, 16).”

    From Defining the human C2H2 zinc finger degrome targeted by thalidomide analogs through CRBN (2018) · cites this paper as [3]

    The paper reports CRL4–CRBN-dependent degradation of IKZF1 and IKZF3 by lenalidomide, and says thalidomide and pomalidomide also decreased their abundance (Abstract; page unavailable). It identifies a degradation-determining sequence within an IKZF3 zinc-finger domain, but does not establish the claimed broader set of proteins degraded by all three drugs through a C2H2 zinc-finger degron. (LLM, conf=0.84)

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.
