Array-CGH in human glial brain tumors

ABSTRACT: Set of arrays organized by shared biological context, such as organism, tumors types, processes, etc. Characterization of DNA copy number changes in 54 glial brain tumors using a cDNA microarray-based comparative genomic hybridization method. Tumors: 54 fresh-frozen glioma specimens subjected to standard WHO classification. Specimens included astrocytic [3 juvenile pilocytic astrocytomas, 1 low-grade astrocytic glioma, 3 anaplastic astrocytomas, 31 glioblastomas (of these 3 secondary glioblastomas and 2 gliosarcomas)], oligodendroglial [5 oligodendrogliomas, 3 anaplastic oligodendrogliomas], and 7 anaplastic oligoastrocytomas tumors. One tumor had been classified as glioneuronal neoplasm. Human male and female genomic reference DNA was purchased from Promega (Promega, Madison, WI). The res
