此前的研究表明,一个人看起来的年龄是由基因和环境因素共同导致的。其他研究已经表明,外表年龄也是非常重要的,它能够反映一个人的实际健康状况和过早死亡的风险。
For the current study, scientists examined the genomes of more than 2,600 elderly Dutch Europeans "for DNA variants associated with differences in perceived facial age and wrinkling as estimated from digital facial images," the report said. "The strongest hits for perceived facial age were for DNA variants in the MC1R gene."
在当前的研究中,科学家们对2600多个荷兰老人的基因组进行了检测。报告指出,科学家们发现,人们实际的面部年龄以及数字面部图像中起皱情况的不同,都与DNA变异有关。“实际面部年龄最显老的是拥有MC1R基因变体的那些人。”
Researchers said they were able to confirm their finding in two other large European studies. The influence of the MC1R gene variant was not swayed by age, sex, skin color, or sun damage.
研究人员表示,他们的发现也得到了另外两项更大型欧洲研究所的证实。MC1R基因变异的影响不会随着年龄、性别、皮肤颜色和晒伤而有所改变。
