The identification and characterization of genes either induced or repressed in human brain tumors are important in understanding the mechanism of tumor initiation and progression, stages of malignancy, in developing new approaches to the diagnosis and treatment of tumors. In this paper, differential hybridization of arrayed human fetal brain and postnatal brain and postnatal brain cDNA libraries revealed differences in the rate of hybridization signals with total cDNA probes of the human brain and glioblastoma multiforme for more than 150 cDNA clones. Sixteen nucleotide sequences with changed contents in tumors were identified by repeated differential hybridization of the cDNA clones selected by primary screening with the same total cDNA probes of the human brain and glioblastoma multiforme and by Northern-hybridization of RNA samples from the human and glial tumors. The results of an analysis of the increased expression of the gene encoding apolipoprotein E. DNA-binding protein B, mitochondrial (16S and 12S) and cytoplasmic 28S rRNAs, Alu-containing transcripts, inactivation of cullin 1 gene and potential tumor suppressor gene TSC-22 are described. |
