Chemokines in Ewing sarcoma
Â
Ewing sarcoma is an aggressive primary malignant bone tumor with high degree of tumor vascularization and is the second most common sarcoma of bone in children and young adults. Patients with disseminated disease at diagnosis or early relapse have a poor prognosis. To identify novel therapies and biomarkers for these patients we focused on the chemokines and chemokine receptors in Ewing sarcoma cells and their role its tumor microenvironment.
CCL21 CXCL14, CXCR7 and the ratio between CXCR4-1 and CXCR4-2 have been identified as candidate prognostic markers, CCL21 immunotherapy as potential therapy and CXCR4 as potential therapeutic target in EWS. In addition, the presented peptide-based life cell imaging methods improve the ability to study CXCR4 cell membrane expression and dynamics qualitatively and quantitatively. This approach might be helpful for the measurement of anti-CXCR4 therapy efficacy. This work identified specific the chemokine signaling pathways that can be used to target Ewing sarcoma and its tumor microenvironment.
