Abstract

Significance Enzymes of the folate cycle are among the most consistently overexpressed proteins in cancer. Whereas multiple clinical agents inhibit thymidylate synthase, no current drugs target the incorporation of one-carbon into folates via serine hydroxymethyltransferase (SHMT). Using genetics, we show that cancer cells require SHMT to generate tumors. We then describe small-molecule SHMT inhibitors, and show that they block the growth of many human cancer cells, with B-cell lymphomas particularly sensitive to SHMT inhibition. We find that this sensitivity arises from the lymphomas’ inability to import the amino acid glycine, which is made as a byproduct of the SHMT reaction. Thus, B-cell lymphomas have an intrinsic defect in amino acid import, which causes a therapeutically targetable metabolic vulnerability.

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.
