摘要
核糖核苷酸还原酶M1(RRM1)是DNA合成通路中的限速酶,RRM1的表达可抑制肿瘤细胞增殖,引起细胞凋亡。早期肺癌患者高RRM1表达水平提示预后较好,晚期患者高RRM1表达水平提示预后较差。RRM1是吉西他滨的分子作用靶点,是吉西他滨耐药的一个重要的预测指标,RRM1过表达者对吉西他滨化疗不敏感。
Ribonueleotide reductase M1 (RRM1) is the key enzyree in DNA synthesis pathway. RRM1 expression inhibits tumor cell proliferation and induces apoptosis. High RRM1 expressions are predictive of better survival in early NSCLC and poor survival in advanced NSCLC . RRM1 is a molecular target of gemcitabine. RRM1 expression is a crucial predictive marker in gemcitabine-resistance patients. RRM1 overexpression indicates resistance to gemcitabine.
