It is considered that can replace laboratory primates in the study of nervous system diseases. To date, however, protein expression in the brain of has not been fully understood.
Three age groups of -15 days, 3 months and 1.5 years-were selected to study their hippocampal protein expression profiles.
A significant difference was observed between the 15-day group and the other two age groups, where as there were no significant differences between the 3-month and 1.5-year age groups. The Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis found that differentially expressed proteins could be enriched in several pathways related to neurovascular diseases, such as metabolic pathways for Alzheimer's disease (AD), Huntington's disease, Parkinson's disease, and other diseases. The KEGG enrichment also showed that relevant protein involved in oxidative phosphorylation in the hippocampus of for 15days were downregulated, and ribosomal proteins (RPs) were upregulated, compared to those in the hippocampus of the other two age groups.
It was suggested that when the hippocampus of developed from day 15 to 3 months, the expression of oxidatively phosphorylated proteins and RPs would vary over time. Meanwhile, the hippocamppal protein expression profile of after 3 months had become stable. Moreover, the study underlines that, during the early development of the hippocampus of , energy demand increases while protein synthesis decreases. The mitochondria of changes with age, and the oxidative phosphorylation metabolic pathway of mitochondria is closely related to neurovascular diseases, such as stroke and cerebral ischemia.
人们认为[未提及具体物种,原文此处表述有误]可在神经系统疾病研究中替代实验灵长类动物。然而,迄今为止,[未提及具体物种,原文此处表述有误]大脑中的蛋白质表达尚未完全明确。
选取了-15天、3个月和1.5岁三个年龄组来研究其海马体蛋白质表达谱。
在15天龄组与其他两个年龄组之间观察到显著差异,而3个月龄组和1.5岁龄组之间没有显著差异。京都基因与基因组百科全书(KEGG)分析发现,差异表达的蛋白质可富集于与神经血管疾病相关的多种途径,如阿尔茨海默病(AD)、亨廷顿病、帕金森病及其他疾病的代谢途径。KEGG富集还表明,与其他两个年龄组的海马体相比,15天龄[未提及具体物种,原文此处表述有误]海马体中参与氧化磷酸化的相关蛋白质下调,核糖体蛋白(RPs)上调。
有人提出,当[未提及具体物种,原文此处表述有误]的海马体从15天发育到3个月时,氧化磷酸化蛋白和核糖体蛋白的表达会随时间变化。同时,3个月后[未提及具体物种,原文此处表述有误]的海马体蛋白质表达谱已变得稳定。此外,该研究强调,在[未提及具体物种,原文此处表述有误]海马体的早期发育过程中,能量需求增加而蛋白质合成减少。[未提及具体物种,原文此处表述有误]的线粒体随年龄变化,线粒体的氧化磷酸化代谢途径与中风和脑缺血等神经血管疾病密切相关。
