Abstract

Osteosarcoma is the most common primary bone tumor, but the pathogenesis is not well understood. While cyclooxygeanse-2 (COX-2) is known to be closely associated with tumor growth and metastasis in several kinds of human tumors, the function of COX-2 in osteosarcoma is unclear. Therefore, to investigate the function of COX-2 in osteosarcoma, we established stable cell lines overexpressing COX-2 in U2OS human osteosarcoma cells. COX-2 overexpression as well as prostaglandin E2 treatment promoted proliferation of U2OS cells. In addition, COX-2 overexpression enhanced mobility and invasiveness of U2OS cells, which was accompanied by increases of matrix metalloproteinase-2 and -9 (MMP-2 and -9) activities. Selective COX-2 inhibitors, NS-398 and celecoxib, inhibited cell proliferation and abrogated the enhanced mobility, invasiveness and MMP activities induced by COX-2 overexpression. These results suggest that COX-2 is directly associated with cell proliferation, migration and invasion in human osteosarcoma cells, and the therapeutic value of COX-2 inhibitors should be evaluated continuously.

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

  • COX/PTGS enzymes are typically induced in response to inflammation in vivo and are not found to be expressed in U2OS cells according to the Human Protein Atlas database.

    “Since COX/PTGS enzymes are typically induced in response to inflammation in vivo46 and are not found to be expressed in U2OS cells according to the Human Protein Atlas database (https://www.proteinatlas.org/ENSG00000095303-PTGS1/cell+line), this compound is not expected to show strong and specific phenotypic responses in this cell model (Fig. 7d).”

    From A statistical framework for high-content phenotypic profiling using cellular feature distributions (2022) · cites this paper as [46]

    The Introduction says COX-2 expression is induced by various stimuli, but does not specify inflammation in vivo or extend that statement to COX/PTGS enzymes generally. The U2OS expression claim is attributed separately to the Human Protein Atlas URL, not to this paper. (LLM, conf=0.82)

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.
