Outline of Final Research Achievements |
Telomere maintenance is mandatory for cancer proliferation. In this research, we investigated the mechanisms of telomere lengthening or maintenance in meningiomas. Upregulating mutations in the promoter of telomerase reverse transcriptase were infrequent in meningiomas, and were invariably observed in aggressive malignant meningiomas. We also analyzed the activity of telomerase in meningioma samples, but telomerase reactivation was not observed in most tumors. Thus, telomerase is rarely reactivated in meningiomas, and this type of brain tumor might depend on other mechanisms of telomere lengthening.
