摘　　要：肺癌是世界范围内发病率和死亡率较高的恶性肿瘤之一。端粒和端粒酶与肺癌的发生发展密切相关。虽然端粒酶可能不是导致细胞癌变的直接原因,但在维持端粒长度和肿瘤生长方面起到关键作用。包括肺癌在内的大部分肿瘤端粒长度缩短。端粒长度的变化与肺癌发生风险相关,并可能成为肺癌的治疗靶标和预测指标。针对端粒和端粒酶信号通路的靶向治疗药物正在探索中,以端粒酶抑制剂为代表的小分子药物有希望应用于肺癌的临床治疗中。但是,人们对于端粒和端粒酶的研究还远远不够,端粒长度维持的旁路作用机制可能是下一步需要深入研究的方向。Lung cancer is one of the malignant tumors with high incidence rate and high mortality worldwide. Telomere and telomerase are closely related to the occurrence and development of lung cancer. Although telomerase may not be the direct cause of carcinogenesis, it plays a key role in maintaining telomere length and tumor growth. The length of most tumors, including lung cancer, is shortened. The change of telomere length is related to the risk of lung cancer, and may become the therapeutic target and predictive index. Target drugs for telomere and telomerase signaling pathway are constantly being explored, and drugs represented by telomerase inhibitors are expected to be used in clinical treatment of lung cancer in the future. However, the research on telomere and telomerase is far from enough. The bypass mechanism of telomere length maintenance may be the direction of further research.
