中文摘要
在K562人红系细胞中过表达ETO2和染色质免疫沉淀分析表明,ETO2直接抑制红系的代表性基因,包括珠蛋白基因。随后,我们用脐带血cd34阳性细胞建立了红细胞分化系统。通过该系统,我们证明了短发夹RNA (shRNA)介导的脐带血cd34阳性细胞源性原代红母细胞ETO2的敲低导致球蛋白基因的显著调节。
英文摘要
Overexpression of ETO2 as well as chromatin immunoprecipitation analysis in K562 human erythroid cell line revealed that ETO2 directly represses representative erythroid genes, including globin genes. Subsequently, we established erythroid differentiation system from cord blood CD34-positive cells. By using the system, we demonstrated that short hairpin RNA (shRNA)-mediated knockdown of ETO2 in cord blood CD34-positive cell-derived primary erythroblasts resulted in the significantupregulation of globin genes.
