衰老与寿命研究
衰老的研究一直是令人非常着迷的课题,人类经历了几千年的文明,至今仍没有阐明衰老的机制。无论是从药物的研发还是基因研究上,衰老都是一个值得投入的方向。
秀丽隐杆线虫近2万个基因中,60-80%都与人类保守,影响衰老的经典信号通路-胰岛素信号通路是在线虫中最早被发现的,其它影响衰老的信号通路,如FOXO信号、TOR信号、sirtuin信号、饮食限制等都与人类保守。并且线虫寿命短,常温条件下寿命只有2-3周,适合做衰老表型及机制的研究。
我们提供服务的内容包括:
(1)检测基因或药物对线虫寿命的影响,发现潜在的抗衰老的基因或药物。
(2)利用遗传学方法对由基因或药物引起的效应进行机制研究,主要包括FOXO信号通路、类胰岛素信号、生殖系信号、饮食限制信号、TOR信号等。
(3)检测线虫体内自由基水平、肌肉退化程度、基因表达水平、daf-16核定位水平、运动水平等。
