Using HIV Virus to Cure Cancer
Scientists are planning to use human immunodeficiency (免疫缺陷) virus (HIV) , one of mankind's most feared viruses, as a carrier of genes which can fight cancer and a range of diseases that cannot be cured. The experts say HIV has an almost perfect ability to avoid the body's immune (免疫的)defenses, making it ideal for carrying replacement genes into patients' bodies, accordin to the Observer.
A team at the California-based Salk Institute, one of the world's leading research centers on biological sciences, has created a special new breed of HIV and has started negotiations with the U.S. Food and Drug Administration (FDA) to begin clinical gene therapy (治疗) trials this year.The first trials are expected to involve patients suffering from cancers that cannot be cured by surgery although project leader Professor Inder Verma said the HIV technique would have "far wider applications".
The new plan remains very likely to cause controversy since it involves making use of a virus which has caused more than 22 million deaths around the world in the past two decades. Verma said that the idea of using HIV for a beneficial purpose was "shocking" but it is possibly used to cure cancers by having all six of the potentially deadly genes removed.
Illnesses such as various cancers are caused when a gene in a patient's body fails to work properly. In the past two years, breakthroughs in genetics (遗传学) have led gene therapy scientists to try and replace the genes that do not function normally.
Unfortunately, the body's immune defenses have been known to attack the modified genes and make them lose their effects before they can start their task and progress in the field has been held up by the lack of a suitable carder.
The HIV virus has the ability to escape from, and then destroy the immune defense cells designed to protect our bodies and this makes it attractive to scientists as a way of secretly conveying replacement genes into patients' bodies.
HIV can be safely used to cure cancer only if the deadly genes have been removed.()
选项
A.Right
B.Wrong
C.Not mentioned
答案
A
解析
题干:只有致命的基因被消除,HlV才能安全用于治疗癌症。利用关键词deadly gene 和remove可以定位到文章第三段“but it is possibly used to cure cancers by having all six o the potentially deadly genes removed”,意为“但是HⅣV在消除六个潜在致命的基因后才可能被用于治疗癌症”。题干信息与原文信息一致,所以答案为A。
