考研英语阅读篇章: 可能导致精神分裂的80个基因

　　Scientists have uncovered 80 previously unknown genes which may put people at risk of developing schizophrenia, research in Nature suggests.

　　《自然》杂志的研究显示，科学家发现了80个以前未知的基因，这些基因有可能使人们患上精神分裂症。

　　The team says the world's largest genetic study of the disease shows it can have biological causes - putting it on a par with(与……同等) other medical conditions.

　　Led by Cardiff University, the international group believes this could be a launch pad for new therapies.

　　Charities say that holistic approaches(整体分析) to the illness must continue.

　　Scientists have debated the relative role genes play in schizophrenia - a condition which affects more than 24 million people worldwide - for many years.

　　Now a global consortium across 35 countries has examined the genetic make-up of more than 37,000 people with the condition, comparing them with some 110,000 people without the disease.

　　'New biology'

　　Scientists found more than 100 genes that make people more susceptible to schizophrenia- 83 of which have never been pinpointed before.

　　Many of these genes are involved in the relay of chemical messages around the brain.

　　And others are known to be involved in the immune system - affecting the body's natural armoury against disease.

　　Prof Michael O'Donovan of Cardiff University who led the research said: "For many years it has been difficult to develop new lines of treatment for schizophrenia, hampered by a poor understanding of the biology of disease.

　　"Finding a whole new bunch of genetic associations opens a window for well-informed experiments to unlock the biology of this condition and we hope ultimately new treatments."

　　Prof David Curtis of University College London and one of the authors of the research told the BBC: "This study puts psychiatry into the same category as other parts of medicine.

　　"In the past we have struggled with the view that psychiatric conditions are not 'real' illnesses but early genetic studies had limited successes.

　　"Now we show with confidence that there are biological processes going awry(失败，出错)."
