美国科学家最近研究发现,吸烟会减缓肺部细胞产生一种蛋白质的速度,这会导致脱氧核糖核酸受损,进而可能引发肺癌。这一发现有助于人们将来改善肺癌的治疗方法。美国俄勒冈卫生科学大学的研究人员在实验室中用人造气管模拟出吸烟者的肺部环境,研究香烟对细胞中不同蛋白质的影响 Recent studies by U.S. scientists have found that smoking slows the rate at which lung cells produce a protein, which can lead to DNA damage and, in turn, lung cancer. This finding will help people to improve the treatment of lung cancer in the future. Researchers at the Oregon Health Sciences University in the United States simulated the lung environment of smokers with artificial trachea to study the effects of cigarettes on different proteins in cells
