Expression data from glioma patient

Multicentric lesions constitute an increasingly diagnosed subgroup of glioblastoma (GBM) and are more malignant than that of solitary GBM. Understanding their biology is necessary and urgent for glioma patient treatment. However, molecular basis of these lesions are poorly characterized. We used microarrays to determine the gene expression profiling of three lesions from one multicentric GBM. We sought to obtain expression profile of three lesions from one multicentric GBM patient. Three lesion tissues were selected for RNA extraction and hybridization on Affymetrix microarrays.
