Abstract

The translational control of oncoprotein expression is implicated in many cancers. Here we report an eIF4A RNA helicase-dependent mechanism of translational control that contributes to oncogenesis and underlies the anticancer effects of silvestrol and related compounds. For example, eIF4A promotes T-cell acute lymphoblastic leukaemia development in vivo and is required for leukaemia maintenance. Accordingly, inhibition of eIF4A with silvestrol has powerful therapeutic effects against murine and human leukaemic cells in vitro and in vivo. We use transcriptome-scale ribosome footprinting to identify the hallmarks of eIF4A-dependent transcripts. These include 5' untranslated region (UTR) sequences such as the 12-nucleotide guanine quartet (CGG)4 motif that can form RNA G-quadruplex structures. Notably, among the most eIF4A-dependent and silvestrol-sensitive transcripts are a number of oncogenes, superenhancer-associated transcription factors, and epigenetic regulators. Hence, the 5' UTRs of select cancer genes harbour a targetable requirement for the eIF4A RNA helicase.

  • Less than 1% of the transcriptome depends on eIF4A, including key growth and cell death factors such as MYC, BCL2, MCL1, CDK4, CCND3, EZH2, NOTCH1.

    “Specifically, they reveal that less than 1% of the transcriptome depends on eIF4A and, importantly, these eIF4A-dependent genes include key growth and cell death factors such as MYC, BCL2, MCL1, CDK4, CCND3, EZH2, NOTCH1, and others [21,23].”

    From NRF2 Activation Confers Resistance to eIF4A Inhibitors in Cancer Therapy (2021) · cites this paper as [21]

    The Discussion (page unavailable) identifies eIF4A-sensitive oncogene transcripts including MYC, NOTCH and BCL2, supporting the general point. But the Results, under “Ribosome footprinting” (page unavailable), report 281 transcripts with reduced translational efficiency among approximately 11,128 protein-coding genes—not less than 1%. The copy does not establish MCL1 or CDK4 as eIF4A-dependent; its mentions of CCND3 and EZH2 do not establish that designation either. (LLM, conf=0.90)

  • Silvestrol blocks translation of MYC and BCL2 mRNAs without affecting the GAPDH housekeeping gene across several lymphoma lines.

    “Consistent with our previous findings [21], we see that silvestrol blocks the translation of the MYC and BCL2 mRNAs, without affecting the GAPDH housekeeping gene, across several lymphoma lines (SuDHL-4, SuDHL-6, SuDHL-10, Ly8) (Figure 1D).”

    From NRF2 Activation Confers Resistance to eIF4A Inhibitors in Cancer Therapy (2021) · cites this paper as [21]

    The Results section, “What transcripts are affected by Silvestrol?” (page unavailable), reports effects on MYC and says housekeeping genes showed no change in ribosome-footprint profiles; the Discussion also identifies BCL2 as a silvestrol-sensitive oncogene. Our copy does not establish unchanged GAPDH translation specifically. The named lymphoma lines are presented as the citing authors’ new observation, not a finding attributed to this source. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • NRF2 activation increases baseline translation of eIF4A-dependent mRNAs with multiple GQ elements in their 5′ UTRs, such as MYC and BCL2.

    “Consistently, by comparing mRNA and protein levels, we observe increased baseline translation of eIF4A-dependent mRNAs with multiple GQ elements in their 5′ UTRS, such as MYC (six GQ elements) and BCL2 (five GQ elements) [21] (Figure 3D,E and Figure S3C–E).”

    From NRF2 Activation Confers Resistance to eIF4A Inhibitors in Cancer Therapy (2021) · cites this paper as [21]

    The Discussion identifies MYC and BCL2 as eIF4A-sensitive transcripts and says such transcripts typically harbor several G-quadruplexes in their 5′ UTRs. Our copy does not substantiate the specific counts of six for MYC and five for BCL2. The increased baseline translation is presented in the citing sentence as the citing authors’ own observation, not a finding attributed to this source. (LLM, conf=0.85)

  • EIF4A inhibitors block the pro-oncogenic translation program and produce powerful anti-cancer effects with limited effects in non-proliferative tissues.

    “EIF4A inhibitors block this pro-oncogenic translation program and produce powerful anti-cancer effects with limited effects in non-proliferative tissues [21,23].”

    From NRF2 Activation Confers Resistance to eIF4A Inhibitors in Cancer Therapy (2021) · cites this paper as [21]

    The Results section ('eIF4A is an oncogene in T-ALL'; page not provided) reports that eIF4A inhibitors suppress oncoprotein expression, delay tumour growth, and are well tolerated in mice. The Extended Data describe toxicity assessments, but the paper does not specifically establish limited effects in non-proliferative tissues. (LLM, conf=0.85)

  • CR-1-31 B treatment was generally well tolerated and did not result in weight loss or mortality in mice.

    “Consistent with our prior analysis of the in vivo toxicity [21], we find that the treatment was generally well tolerated and did not result in weight loss or mortality (Figure S1E).”

    From NRF2 Activation Confers Resistance to eIF4A Inhibitors in Cancer Therapy (2021) · cites this paper as [21]

    The Results section states that detailed toxicology found (±)-CR-31-B treatment well tolerated in mice. Extended Data Figure 3 describes weight monitoring, and the Toxicity studies procedures describe clinical observation, but our copy does not explicitly report no weight loss or treatment-related mortality. (LLM, conf=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.
