Research Abstract

BMI-1 plays an important role in selfrenewal of hematopoietic stem cells as well as leukemic stem cells. We investigated the expression in CD34^+ cells from chronic myeloid leukemia (CML). BMI-1 expression was significantly higher in chronic phase compared to controls, and was further increased during the course of the disease progression, accelerated phase and blastic phase. These results suggest the usefullness of BMI-1 expression in CD34^+ cells as a molecular marker for monitoring CML patients in addition to as a therapeutic molecular target. In Lymphoma, high BMI-1 expression was found resistant to both etoposide and oxaliplatin through enhanced expression of survivin.
