Why do some people look old? "Old" genes have been found that the gene-and older-IT information

Why do some people look old?

A United Nations study found that it is likely determined by their genes. Researchers showed volunteers facial HD photos of more than 4,000 people and let them guess the age of the person in the photo, and that more than 4,000 people to do genetic testing. Results showed that a technique called melanocortin 1 receptor (MC1R) gene is closely linked to whether old.

? Frame-independent

Published in current biology, the researchers reported that MC1R is a major gene controlling melanin synthesis, it can make a person look older than their actual age on average 2. More than 4,000 people involved in the experiment, about half of those with MC1R gene, and the other half did not, which does look younger than the former. Researchers at Erasmus University in Rotterdam manfuleide·kaize believe that gene that old effect similar to smoking. He said that this was discovered by the human genes associated with age, if we can continue to find similar genes, understanding how they affect the countenance of change, is expected to realize the dream of man's eternal youth.

为什么有些人看着显老？

一项多国联合研究发现，这很可能由他们的基因决定。研究人员向众多志愿者展示4000多人的面部高清照片，让他们据此猜测照片中人的年龄，然后对这4000多人做基因检测。结果发现，一种叫做黑素皮质素受体1（MC1R）的基因与人是否显老密切相关。

研究人员在《当代生物学》上发表报告说，MC1R是控制黑色素合成的主要基因，它能使人看上去比实际年龄平均老2岁。参与实验的4000多人中，约半数人带有MC1R基因，另一半人没有，而后者确实比前者看上去年轻。鹿特丹伊拉斯谟大学的研究人员曼弗雷德·凯泽认为，基因造成的显老效果与吸烟类似。他说，这是人类首次发现基因与显老之间的关联，如果能继续找到类似基因，了解它们如何影响人的面貌变化，将有望实现人类永葆青春的梦想。
