Prognostic Relevance of CCN3 in Bone Sarcomas
Osteosarcomas and Ewing’s sarcoma (EWS) are aggressive malignant bone tumors. In both cases, prognostic markers are lacking. Presently, only clinical features are widely accepted as prognostic indicators. In this study we assessed the prognostic value of CCN3 (Nov), a matricellular protein that belong to the CCN family of regulatory proteins, whose members were shown to play crucial roles in bone formation. In osteosarcomas, CCN3 expression levels represent a useful tool to early identification of patients with different prognosis. In both osteosarcomas and Ewing’s sarcomas, the expression of a full length CCN3 protein was associated to a worse prognostic and a higher risk to developing met…
Prognostic relevance of CCN3 in Ewing sarcoma
Ewing sarcoma is a highly aggressive malignant bone tumor occurring preferentially in children and young adults. At present, only clinical features, such as patient age, presence of clinically evident metastases at diagnosis, and poor response to neoadjuvant chemotherapy, are widely accepted as prognostic indicators in Ewing sarcoma. In this study, we assessed the prognostic value of CCN3 (Nov), a matricellular protein that play crucial roles in bone formation. Polyclonal antibodies directed against each of the different CCN3 modules were used to identify variant CCN3 proteins in tumors and to draw potential relationships between the expression of these variants and the outcome of patients …
