Research Abstract

It has been known that intracellular reaction oxygen specie (ROS)levels influence the maintenance of the stem cells. Nrf2 is a transcription factor that regulates the expression of antioxidant enzymes. In this study we analyzed the function of Nrf2 on hematopoietic system in mice. We found that Nrf2 negatively regulate cell-cycle progression of hematopoietic stem cells and contribute to the lineage commitment of multipotential progenitors.
