中科院动物所研究人员最近发现了吸烟引起肺癌的关键炎症因子。相关成果日前发表于《癌症通讯》杂志。数据显示,每年近160万肺癌死亡病例中有90%为吸烟引起。烟草中含有5000种化合物,其中73种对实验动物和人类具有致癌性。吸烟可引起DNA损伤和基因突变,但吸烟引起肺癌的机理仍未阐明,而这是开发肺癌防治策略的前提。
Researchers at the Institute of Zoology Chinese Academy of Sciences recently discovered the key inflammatory factors in lung cancer caused by smoking. Related results recently published in the “Cancer Newsletter” magazine. Data show that nearly 160 million lung cancer deaths each year, 90% of cases caused by smoking. Tobacco contains 5000 compounds, of which 73 are carcinogenic to laboratory animals and humans. Smoking can cause DNA damage and gene mutation, but the mechanism of smoking caused lung cancer has not yet been elucidated, and this is the prerequisite for the development of lung cancer prevention and control strategies.
