新的DNA甲基化时钟可准确估算斑纹鲨年龄

研究人员开发了一种新方法,利用其血液中的DNA甲基化模式来估算斑纹鲨的年龄。这种新的表观遗传时钟可以预测鲨鱼的年龄,其中位数误差为一到两年,仅利用基因组中几个特定位点的信息。这一突破意义重大,因为鲨鱼寿命多样且进化历史悠久,在衰老研究方面一直是一个挑战。研究结果表明,一些基本的衰老生物学机制,如DNA甲基化模式,可能在巨大的进化距离上得以保留,甚至在鲨鱼和哺乳动物之间也是如此。 AI

    鲨鱼DNA能教会我们什么关于衰老生物学

    What if we could estimate a shark’s age from a small blood sample rather than counting growth rings in its vertebrae? New research on zebra sharks has developed an “epigenetic clock” that can predict age with surprising accuracy, using changes in DNA methylation at just 10 sites.…
