通过改变被称为雷帕霉素靶蛋白(mTOR)的基因的活动，NIH的科学家将老鼠的寿命平均延长了20%左右。研究人员还发现，相比对照组老鼠，上述老鼠在衰老的过程中，记忆、认知和其它一些重要特征都得到了较好的保护。对照组的老鼠体内，与这种基因相关的蛋白质水平处在正常范围。研究显示mTOR基因是衰老过程的主要调节器。虽然对鼠类的研究并不总是能适用于人类，但研究人员说，这个结果提出了这样一个可能性，即用阻止其活动的药物瞄准该基因或许有一天至少会成为人类延寿战略的一部分。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
