Abstract

A high rate of aerobic glycolysis was catalyzed by rat-1 cells transfected with a ras oncogene (ras cells); rat-1 cells and rat-1 cells transfected with myc oncogene (myc cells) showed a low rate of glycolysis that was increased after exposure of the cells to type B transforming growth factor (TGF-beta). The uptake of radioactive methylaminoisobutyric acid or L-methionine via system A of amino acid transport also was accelerated after exposure of these cells to TGF-beta, with the myc cells being most sensitive and the ras cells least sensitive. Methionine was found to be a potent inhibitor of glycolysis in ras cells as well as in rat-1 or myc cells that were exposed to TGF-beta. We propose a relationship between the product of the ras oncogene (p21) and the protein(s) induced by exposure to TGF-beta.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Oncogenic KRAS upregulates PFK1, ENO1, and LDHA, promoting glycolytic flux and production of intermediates that can enter anabolic pathways.

    “Oncogenic KRAS also upregulates expression of other key glycolytic enzymes, such as PFK1, ENO1, and LDHA28,31–33, thereby promoting glycolytic flux and enabling the production of glycolytic intermediates that can be shunted into other anabolic pathways (Fig 2).”

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.
