Drinking alcohol can increase your risk of cancer because ethanol is itself a carcinogen on certain parts of the body, scientists have found.
科学家发现，喝酒会增加罹患癌症的风险，因为对某些身体部位来说，乙醇本身就是一种致癌物质。
Researchers said they found that when ethanol is broken down by the body, it can cause DNA damage that may lead to dangerous changes to the cells.
研究人员称，他们已经发现，被身体分解后的乙醇会破坏DNA，导致细胞发生危险变异。
The US team from the National Institute on Alcohol Abuse and Alcoholism in Maryland, used human cells engineered to produce an enzyme that is found in liver and breast tissue.
The results confirmed that the alcohol (ethanol) was being converted to acetaldehyde, causing DNA damage and switching on the cell's DNA repair genes.
结果表明，酒精（乙醇）转换成乙醛后破坏DNA，激活细胞内DNA的修复基因。
Study author Philip J Brooks, said:"Although the link between drinking alcohol and certain types of cancers was first established in the 1980s the existence of such a relationship did not prove that alcohol itself caused the cancers.
"In most people, acetaldehyde is quickly converted to acetate, a relatively harmless substance, by an enzyme called ALDH2."
“大部分人的身体都会通过一种叫做ALDH2的酶迅速将乙醇转化成一种相对无害的物质——醋酸盐。”
"However, approximately 30 percent of East Asians are unable to metabolize alcohol to acetate due to a genetic variant in the ALDH2 gene, and have a greatly elevated risk of oesophageal cancer from alcohol drinking," he added.
keep a good habit about life so that you can have a good body.as the proverb says"An apple a day keeps the doctor away." we should keep the high quality and small quantity.作者: 簿子酒 时间: 2013-1-5 14:06
