Abstract

Background: Osteosarcoma (OS) is a primary malignant tumor of the bone that typically presents in the second decade of life and has a poor prognosis, especially in metastatic cases. Wnt signaling contributes to the pathogenesis of tumors such as colon cancer and malignant melanoma. Wnt signaling controls normal bone formation during embryogenesis and homeostasis in adult organisms, thus we evaluated Wnt signaling in OS. Procedure: We surveyed the expression of Wnts, their receptors, Frizzleds and LRPs, and soluble Wnt inhibitors (sFRPs) in four OS cell lines by RT‐PCR. We also tested biological response of OS cell lines to exogenous Wnts by measuring β‐catenin stabilization, Dvl phosphorylation, TOPFLASH activity and chemotaxis. Human OS tumor microarrays were evaluated for expression of Wnt10b by immunohistochemistry. Results: All cell lines tested showed expression of at least three Wnts and one Frizzled. Exogenous Wnt3a and Wnt10b treatment induced Dvl phosphorylation, β‐catenin stabilization and TCF4 transcriptional activity in both metastatic and non‐metastatic murine OS cell lines. Metastatic OS cell lines showed better chemotaxis response to Wnts than the non‐metastatic OS cell lines. Immunohistochemistry studies of 44 human OS samples demonstrated that Wnt10b expression correlated with decreased overall survival. Conclusions: These results further supports a possible autocrine or paracrine Wnt pathway in metastatic potential of OS. Pediatr Blood Cancer 2008;51:349–355. © 2008 Wiley‐Liss, Inc.

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.
