Ageing is a phenomenon where the accumulation of all the stresses that alter the functions of living organisms, halter them from maintaining their physiological balance and eventually lead to death. The emergence of epigenetic tremendously contributed to the knowledge of ageing. Epigenetic changes in cells or tissues like deoxyribonucleic acid (DNA) methylation, modification of histone proteins, transcriptional modification and also the involvement of non-coding DNA has been documented to be associated with ageing. In order to study ageing, scientists have taken advantage of several potential organisms to aid them in their study. has been an essential model in establishing current understanding of the mechanism of ageing as they possess several advantages over other competitors like having homologues to more than 75% of human disease genes, having 50% of genes are homologues to human genes and most importantly they are genetically amenable. Here, we would like to summarise the extant knowledge about ageing and epigenetic process and the role of as an ideal model to study epigenetics in association with ageing process.
衰老现象是指所有改变生物体功能的压力不断积累,阻碍生物体维持生理平衡并最终导致死亡。表观遗传学的出现极大地推动了人们对衰老的认识。细胞或组织中的表观遗传变化,如脱氧核糖核酸(DNA)甲基化、组蛋白修饰、转录修饰以及非编码DNA的参与,都已被证明与衰老有关。为了研究衰老,科学家利用了几种潜在的生物体来辅助他们的研究。 已成为建立当前对衰老机制理解的重要模型,因为它们相对于其他生物体具有多个优势,例如与超过75%的人类疾病基因具有同源性,50%的 基因与人类基因同源,最重要的是它们在遗传上易于操作。在此,我们将总结关于衰老和表观遗传过程的现有知识,以及 将作为研究与衰老过程相关表观遗传学的理想模型所发挥的作用。
