为什么有人显老,有人显得年轻?身体组织和器官的年龄和你真实年龄的差距有多大?让『科学算命』来告诉你们吧。如何得知身体的真实年龄?现在,美国加利福尼亚大学的研究者能通过表观遗传来推断身体组织或者器官的实际年龄。研究者从51种不同的人体组织中获取了7844个健康组织的样本,然后对样本组织的甲基化程度一一进行检测。组织样本的提供者上至101岁的老人,下至还没有出生的胎儿,研究者希望从中一窥甲基化与年龄之间的联系。
Why do some people become older and others appear younger? What is the difference between the age of your body tissues and organs and your true age? Let “science fortune-telling” tell you. How to know the real age of the body? Now, researchers at the University of California, USA, can deduce the actual age of the body tissue or organ by epigenetics. The researchers obtained samples of 7844 healthy tissues from 51 different human tissues, and then examined the degree of methylation of the sample tissues one by one. Tissue samples are available from the age of 101 to the still unborn, and researchers hope to see the link between methylation and age.
