Islet-l促C 3 H 10 Tl/2向心肌样细胞特化中基因上组蛋白乙酰化作用及相互关系研究
发布时间:2021-03-03 15:34
目的本课题组前期研究发现感染高表达Islet-1(Insulin geneenhancer binding protein-1,胰岛素增强结合因子)慢病毒载体的C3H10T1/2干细胞可被诱导向心肌样细胞特异性分化,心肌特异性蛋白基因Gata4,Nkx2.5,Mef2c表达增高。但Islet-1通过何种方式促使这些心肌特异性蛋白基因表达增高还不甚明了。本文将从表观遗传组蛋白乙酰化修饰的角度,来探讨Islet-1是否通过提高这些心肌特异性基因上组蛋白乙酰化的水平来促进其表达增加,以及心肌基因上组蛋白乙酰化水平的降低对与Islet-1的结合有无影响,最后综合分析明确Islet-1与心肌特异性基因上组蛋白乙酰化的相互关系。材料与方法用DMEM高糖培养基(含有10%胎牛血清)培养从液氮罐中复苏的C3H10T1/2细胞,5%的CO2,37℃孵箱中放置培育,C3H10T1/2细胞属于贴壁细胞,当细胞生长密度为80%左右时按1:3的比例及时传代。按Moi=20加入相对应量的病毒至细胞生长密度为60%的C3H10T1/2细胞,同时加入终浓度为8mg/L相对应量的Polybrene。就好的好的1.对细胞...
