Disordered methionine metabolism in MTAP/CDKN2A-deleted cancers leads to dependence on PRMT5

Abstract

Tumors put in a vulnerable position: Cancer cells often display alterations in metabolism that help fuel their growth. Such metabolic “rewiring” may also work against the cancer cells, however, by creating new vulnerabilities that can be exploited therapeutically. A variety of human tumors show changes in methionine metabolism caused by loss of the gene coding for 5-methylthioadenosine phosphorylase (MTAP). Mavrakis et al. and Kryukov et al. found that the loss of MTAP renders cancer cell lines sensitive to growth inhibition by compounds that suppress the activity of a specific arginine methyltransferase called PRMT5. Conceivably, drugs that inhibit PRMT5 activity could be developed into a tailored therapy for MTAP-deficient tumors. Science , this issue pp. 1208 and 1214

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

  • Loss of MTAP causes MTA to accumulate, and this MTA can inhibit PRMT5, creating a vulnerability in cancer cells.

    “Loss of MTAP expression can result in another vulnerability for cancer cells because the MTA that accumulates following MTAP loss can act as a potent inhibitor of the enzyme arginine methyltransferase 5 (PRMT5).”

  • Deletion of CDKN2A results in concomitant deletion of MTAP in many cancers, including 53% of glioblastomas and 26% of pancreatic cancers.

    “Deletion of the tumor suppressor CDKN2A results in concomitant deletion of the methionine salvage pathway enzyme methylthioadenosine phosphorylase (MTAP) in many cancers, including 53% of glioblastomas and 26% of pancreatic cancers (Mavrakis et al., 2016).”

    From Targeting Metabolism for Cancer Therapy (2017) · cites this paper as Mavrakis et al., 2016

  • MTAP-null cancer cells are more sensitive to PRMT5 depletion than isogenic cancer cells that express MTAP.

    “MTAP loss results in reduced PRMT5 activity and renders MTAP-null cancer cell more sensitive to PRMT5 depletion than isogenic counterparts that express MTAP (Kryukov et al., 2016; Marjon et al., 2016; Mavrakis et al., 2016).”

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.
