中文摘要
双联蛋白被认为是DNA复制和染色质重塑的调节剂。Geminin蛋白的表达受Polycomb group复合物1和Hox蛋白(Hoxb4/Hoxa9)的调控,维持造血干细胞的活性。本研究的代表产生了逆转录病毒载体系统,修改了Geminin的表达水平和Geminin- eyfp敲入小鼠,使Geminin可视化。通过使用这些系统,该代表揭示了Geminin在调节造血干细胞活性中的分子作用。
英文摘要
Geminin is known as a regulator of DNA replication as well as chromatin remodeling. Geminin protein expression is regulated by Polycomb group complex 1 and Hox protein (Hoxb4/Hoxa9), which sustain hematopoietic stem cell activity. The representative of this study generated retroviral vector system modifying Geminin expression level and Geminin-EYFP knockin mice enabling visualization of Geminin. By using these systems, the representative revealed a molecular role for Geminin in regulating hematopoietic stem cell activity.
