摘要 目的 探讨人端粒酶 RNA(human telomerase RNA,h TR)反义 c DNA在体内外对胶质瘤细胞生长的抑制作用。方法 将 h TR反义 c DNA作用于人胶质瘤细胞系 TJ90 5 ,用 MTT法检测细胞存活率、端粒酶重复序列扩增法测定端粒酶活性、RT- PCR法检测 h TR及其人端粒酶催化亚基 (humantelomerase reverse transcriptases,h TERT)表达、观察裸鼠体内肿瘤生长情况等检测其作用效果。结果h TR反义 c DNA在体内外明显抑制肿瘤细胞生长 ,降低端粒酶活性 ,抑制 h TR及 h TERT表达。结论h TR反义 c DNA显著抑制人胶质瘤细胞生长 ,可成为恶性胶质瘤基因治疗的靶基因。
