摘要:


文题释义:

表观遗传学:指基于基因序列在不发生改变的情况下,基因表达水平发生可遗传性改变的一种基因表达网络调控方式,主要包括DNA甲基化、组蛋白修饰和非编码RNA调控等,主要通过对基因转录和翻译过程的调控,影响其功能和特性。
主动脉瘤:是主动脉的局灶性管壁薄弱及扩张(>参考血管直径的50%),为一种具有较高的发病率和破裂后致死率的严重心血管疾病。


背景:表观遗传作为重要的基因表达网络的调控方式,已被证明在血管平滑肌细胞重塑介导主动脉瘤的发生发展中发挥重要作用。

目的:文章从主动脉瘤发生及进展过程中血管平滑肌细胞重塑的表观遗传调控机制进行综述。
方法:以“Aortic aneurysm,Vascular smooth muscle,Smooth muscle cells,Epigenetic,DNA methylation,Histone modification,Non coding RNA”为英文检索词,以“主动脉瘤,血管平滑肌,平滑肌细胞,表观遗传,DNA甲基化,组蛋白修饰,非编码RNA”为中文检索词,分别检索PubMed、Web of Science以及中国知网数据库1970-2022年发表的相关文献,最终纳入71篇文献进行综述。

结果与结论:①表观遗传修饰可通过靶向调节血管平滑肌细胞重塑、细胞外基质降解而影响主动脉瘤的发生进展,可在主动脉瘤治疗、延缓病情及改善预后发挥关键作用。②表观遗传相关酶分子(如DNA甲基化酶和组蛋白修饰酶)可通过调节血管平滑肌重塑如细胞增殖、迁移和凋亡等因素影响主动脉瘤的进展,可作为主动脉瘤药物治疗的参考靶点。③目前表观遗传修饰对主动脉瘤的研究尚处于基础研究阶段,且部分表观遗传修饰机制尚未探究清楚,未来随着此领域研究的不断发展,靶向表观遗传修饰在治疗主动脉瘤以及临床转化过程中有望实现新的突破。

Abstract: BACKGROUND: Epigenetics, as an important regulation mode of gene expression network, has been proved to play an important role in the occurrence and development of aortic aneurysm mediated by vascular smooth muscle cell remodeling.
OBJECTIVE: To review the epigenetic regulation mechanism underlying vascular smooth muscle cell remodeling during the occurrence and progression of aortic aneurysm.
METHODS: Related articles published from 1970 to 2022 were retrieved from PubMed, Web of Science and CNKI databases. The keywords were “Aortic aneurysm, Vascular smooth muscle, Smooth muscle cells, Epigenetic, DNA methylation, Histone modification, Non coding RNA” in English and Chinese. Ultimately, we included 71 articles for review.
RESULTS AND CONCLUSION: Epigenetic modification can influence the occurrence and progression of aortic aneurysm by targeting vascular smooth muscle cell remodeling and extracellular matrix degradation. Targeted epigenetic modification can play a key role in aortic aneurysm treatment, delaying the disease and improving the prognosis. Epigenetic related enzymes, such as DNA methylesterases and histone-modifying enzymes, can influence the progression of aortic aneurysm by regulating vascular smooth muscle cell remodeling, including cell proliferation, migration and apoptosis, and can be used as targets for drug therapy. The research of epigenetic modification on aortic aneurysm is still in the basic research stage and some epigenetic modification mechanisms have not yet been explored. With the development of medical research, targeted epigenetic modification is expected to achieve new breakthroughs in the treatment of aortic aneurysm and clinical transformation.

Key words: aortic aneurysm, vascular smooth muscle, smooth muscle cell, epigenetic, DNA methylation, histone modification, non-coding RNA, review
