Of content of some kind of special protein reduce can spark lung cancer

Lung cancer is the commonnest cancer on the world, diagnose the patient that give every year to be as high as 1.3 million. A lot of research show, there is close connection between smoking and lung cancer, but specific mechanism did not make clear all the time.

　　 lung cancer is the commonnest cancer on the world, diagnose the patient that give every year to be as high as 1.3 million. A lot of research show, there is close connection between smoking and lung cancer, but specific mechanism did not make clear all the time.

　　 scientist discovered recently, of content of some kind of special protein reduce can cause DNA loss, spark thereby lung cancer. This one discovery may conduce to a scientist improving the treatment to lung cancer in the future. Relevant paper is online on May 13 publish at " British cancer magazine " on.

This plants 　 　 special albumen name is FANCD2, the protein that it is in is familial as exsanguine as transmissibility Fan Keni about. Have this exsanguine person, this familial protein content is low, be in more easily young when contract cancer.

　 　 the lung environment that researcher created a person to build tracheal imitate nicotian in the lab, studied with this cigarette is right the influence that albumen differs in the cell. Result discovery, expose when lobar cell at cigarette is medium, the production rate of FANCD2 can go delay, bring about its content to reduce. And the action of FANCD2 depends on be injured through repairing DNA or be being promoted blemish cell suicide will prevent cancer, so low-level FANCD2 can cause DNA loss, spark thereby cancer.

This one research showed 　 　 FANCD2 is resist importantly cancer protein, and the production process that cigarette can destroy it. Although the likelihood is returned inside this,the bag contains other protein, but a when know FANCD2 is a key, because contain the cell of FANCD2 of very high level,can resist the harm action of cigarette.

This one research increased 　 　 to be opposite the understanding of smoking mortality reason. Smoking is at present those who cause cancer is the biggest onefold can prevent a consideration, there are 9 in 10 lung cancer is smoking be caused by. Good nevertheless news is, smoke of Buddhist monastic discipline is the smoke of —— give up that has effect 5 years hind, the risk of the heart attack will fall the half of nicotian, after 10 years, the risk that contracts lung cancer also is met likewise halve.
