衰老学

Therefore, based on documents reports, through contrastive observation of 20-month-old natural senile mice, this study has confirmed that the anaplasia of subacute senile model mice was obviously similar to the features of 20-month-old naturally physiological senile mice. Mice in both two groups displayed dull color patterns, slow movements, insensitive responses and decrease of growth rates of body weight; hepatic and brain tissues in the mice presented senile features of sero-enzyme such as decrease in SOD activity, increase in content of lipid perhydrides and so on.

为此，本研究在文献报道基础上，通过与20月龄自然老化鼠的对比观察，证实：亚急性衰老模型鼠的退行性变化与20月龄自然生理性老化鼠特征的相近之处鲜明可见。2组均出现毛色暗淡，少有光泽，动作迟缓，反应不灵敏，体重增长率下降；肝、脑组织出现SOD活力下降，脂质过氧化物含量增高等血清酶学的老化特征。

Results as bellows: AtSIRT1 was located in Mitochondrial as hSIRT4 of human, and maybe take part in respiration and electron transformation chain, AtSIRT2 was located in nucleolus as hSIRT6 of human, maybe play important role in extend lifespan;mutation in AtSIRT1 leaded to cotyledon of plant turn to yellow and caused short life span. Mutation in AtSIRT2 could make the color of leaf turn to purple and accumulate a lot of anthocyanin;Sirtinol, a inhibitor of SIRT which did not cause the same model of the mutation of AtSIRT1 and AtSIRT2 indicated that the mechanism of Sirtinol was different from other organism;the structure of AtSIRT1 and AtSIRT2 were similar to other known Sir2, which indicated that they maybe have the same function;AtSIRT2 was overexpressed and its activity was detected.

结果表明，1，拟南芥AtSIRT1与人的同源蛋白hSIRT4相同，定位于线粒体，可能参与呼吸作用和电子传递，SIRT2与人的同源蛋白hSIRT6相同，定位于细胞核，可能同它的功能类似，在延缓衰老及调节细胞寿命方面起作用。2，AtSIRT1突变，可引起幼苗和植株的子叶变黄和早衰；AtSIRT2突变，可引起叶片发紫，沉积大量花青素。3，SIRT蛋白的抑制剂Sirtinol不能表型模写AtSIRT1和AtSIRT2突变体，说明Sirtinol在拟南芥中的作用机制不同于其他生物。4，AtSIRT1和AtSIRT2蛋白质结构预测表明与已知的Sir2蛋白相似，揭示其功能的相似性。5，在大肠杆菌中过量表达了其中一个基因(AtSIRT2)，可体外检测其酶学活性，进一步证明其功能。
