Expression of WNT-5a and ROR2 correlates with disease severity in osteosarcoma.

Osteosarcoma, a common malignancy primarily affecting children, generally has a poor prognosis. Novel diagnostic, prognostic and therapeutic markers are required to ameliorate the negative outcomes of this disease. We investigated two potential markers, WNT-5a and ROR2, which are hypothesized to dysregulate WNT signaling pathways to promote tumorigenesis in other types of cancer.
