ENO2 and leukemia: They reported that treatment of human myeloid HL-205 and erythroid K-562-J leukemia cells for 6 days with different doses of genistein resulted in a time- and dose-dependent inhibition of cell growth and cellular differentiation; the latter was evident by the increased percentage of the cells reacting with OKM 1 monoclonal antibody, positive staining for NSE (a usual feature of monocytes), and expression of NBT dye reduction (a symbol of granulocytic maturation) in the leukaemia cells.
