Progress in epigenetic regulation of vascular smooth muscle cell remodeling in the occurrence and development of aortic aneurysms / 中国组织工程研究

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.
