Genome-wide copy number analysis of patient-derived gliobastoma cell cultures


ABSTRACT: Genome-wide copy number variation profiles were analyzed in the patient-derived gliobastoma cell culture samples. For this purpose, gDNA was analyzed using the CytoScan® assay in combination with a one-color based labeling and hybridization protocol. Signals on the CytoScan® HD microarrays were detected using the Affymetrix GeneChip® 3000 Scanner.

Antiangiogenic therapy of glioblastoma (GBM) with bevacizumab, a VEGFA-blocking antibody, may accelerate tumor cell invasion and induce alternative angiogenic pathways. Here we investigate the roles of the proangiogenic apelin receptor APLNR and its cognate ligand apelin in VEGFA/VEGFR2 antiangiogenic therapy against distinct subtypes of GBM. In proneural GBM, apelin levels were downregulated by VEGFA or VEGFR2 blockade. A central role for apelin/APLNR in controlling GBM vascularization was corr  ...[more]
