Abstract

Rho GTPases impact a number of activities important for oncogenesis. We describe a small molecule inhibitor that blocks oncogenic transformation induced by various Rho GTPases in fibroblasts, and the growth of human breast cancer and B lymphoma cells, without affecting normal cells. We identify the target of this inhibitor to be the metabolic enzyme glutaminase, which catalyzes the hydrolysis of glutamine to glutamate. We show that transformed fibroblasts and breast cancer cells exhibit elevated glutaminase activity that is dependent on Rho GTPases and NF-κB activity, and is blocked by the small molecule inhibitor. These findings highlight a previously unappreciated connection between Rho GTPase activation and cellular metabolism and demonstrate that targeting glutaminase activity can inhibit oncogenic transformation.

  • Inhibitors of glutaminase efficiently induce cancer cell death through dysregulation of the antioxidant system.

    “In addition, inhibitors of the enzyme glutaminase (GLS) that converts glutamine to glutamate, which is subsequently transformed to GSH via the glutamate–cysteine ligase complex, efficiently induce cancer cell death through dysregulation of their antioxidant system72.”

    From ROS in cancer therapy: the bright side of the moon (2020) · cites this paper as [72]

    The Results section (“968 blocks the transforming activity of human breast cancer cells”; page unavailable) reports that the glutaminase inhibitor 968 inhibited cancer-cell growth and colony formation. It does not establish that the inhibitor induced cell death or that its effects resulted from dysregulation of the antioxidant system; the Discussion instead emphasizes effects on glutaminase activity and oncogenic transformation.

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.
