Abstract

Glioblastoma (GBM) is the most aggressive and malignant brain tumor. Recent studies indicated that glioma samples are characterized by increased expression of CXCR4, the CXCL12/SDF-1 chemokine receptor. To better understand the role of CXCR4 in GBM biology we performed an integrated study where we simultaneously evaluate the contribution of the CXCR4/CXCL12 signaling pathway to the proliferation, survival and motility of a human GBM cell line. Our results indicated that CXCR4/CXCL12 axis induced an increase in cell proliferation and in cell motility. The blockage of CXCR4 induced a significant increase of apoptosis. Together, our results indicated that CXCR4/CXCL12 signalling pathway may contribute to GBM development and emphasize the therapeutic potential of this pathway in patients with GBM.
