The amplification of hTERT was detected in glioma tissues, although telomerase activity was not always found within these specimens. The aim of this study was to correlate the level of hTERT transcription with telomerase activity in two glioma age groups. hTERT was significantly transcribed at similar copy numbers in both age groups. However, these mRNAs translated to telomerase in 100% of the young compared to only 25% of the older patients. While hTERT transcription correlated directly to telomerase protein level and activity, as well as longer telomeres in the young group, such correlations were missing in the older group.
在胶质瘤组织中检测到了hTERT的扩增,尽管在这些标本中并非总能检测到端粒酶活性。本研究的目的是在两个胶质瘤年龄组中,将hTERT转录水平与端粒酶活性相关联。在两个年龄组中,hTERT均以相似的拷贝数进行显著转录。然而,这些mRNA在100%的年轻患者中翻译为端粒酶,而在老年患者中只有25%。虽然hTERT转录与端粒酶蛋白水平和活性直接相关,并且在年轻组中与更长的端粒相关,但在老年组中却不存在这种相关性。
