グリオーマ細胞株におけるがん抑制遺伝子変化の解析

Abstract: Ten glioma cell lines were examined for alterations of the p16, p15 and p53 genes, which were tumor suppressor genes with direct or indirect CDK inhibitory functions. All the cell lines showed abnormalities in at least 1 gene, often in 2 or 3 genes coincidentally, suggesting that dysfunction of these genes is closely related to glioma cell growth. On examination of the primary tumor tissues, the same alterations of the p16/p15 and p53 genes as detected in the cell lines were demonstrated in all 6 cases examined, p16/p15 gene deletion in 1, p16 gene mutation in 1 and p53 gene mutations in 5 cases. This suggested that the p16/p15 and p53 gene alterations and their combinations in at least some glioma cell lines reflected those in the primary glioma tissues.
