We have investigated oxidized low-density lipoprotein (ox-LDL) induced senescence in hematopoietic stem cells (HCs). Mouse Sca-1+ HCs were separated and purified using the magnetic activated cell sorting technique. Ox-LDL induced significant senescence in HCs measured by SA-β-Gal staining, and reduced CFU-Mix colony-forming capacity, arresting cells at(More)
AIMS AND BACKGROUND Traditional chemotherapy strategies for human leukemia commonly use drugs based on cytotoxicity to eradicate cancer cells. One predicament is that substantial damage to normal tissues is likely to occur in the course of standard treatments. Obviously, it is urgent to explore therapies that can effectively eliminate malignant cells(More)
OBJECTIVE The effect of angelica sinensis polysaccharides (ASP) on the production of reactive oxygen specie (ROS), the capability of total anti-oxidant (T-AOC), and the expression of p16 in mRNA level in mice hematopoietic stem cells (HSCs) were observed to explore the underlying mechanism that ASP delay aging of HSCs in vivo. METHOD C57BL/6J mice were(More)
The latest findings of our laboratory showed that Angelica sinensis polysaccharide (ASP) showed a definite effect in regulating the aging of hematopoietic stem cells. Leukemia is a type of malignant hematopoietic tumor in hematopoietic stem cells. There have been no relevant reports about ASP's effect in regulating the aging of leukemia cells. In this(More)
OBJECTIVE To observe the effect of Angelica sinensis polysaccharides (ASP) on the length of telomere, the activity of telomerase and the expression of P53 protein in mice hematopoietic stem cells (HSCs), and explore ASP's potential mechanism for regulating HSC aging. METHOD C57BL/6J mice were randomly divided into the normal group, the aging group and the(More)
