Biological indicators of prognosis in Ewing's sarcoma: An emerging role for lectin galactoside-binding soluble 3 binding protein (LGALS3BP)
Starting from an experimental model that accounts for the 2 most important adverse processes to successful therapy of Ewing's sarcoma (EWS), chemoresistance and the presence of metastasis at the time of diagnosis, we defined a molecular signature of potential prognostic value. Functional annotation of differentially regulated genes revealed 3 major networks related to cell cycle, cell-to-cell interactions and cellular development. The prognostic impact of 8 genes, representative of these 3 networks, was validated in 56 EWS patients. High mRNA expression levels of HINT1, IFITM2, LGALS3BP, STOML2 and c-MYC were associated with reduced risk to death and lower risk to develop metastasis. At mul…
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…
