Abstract

In order to clarify the function of P210 bcr/abl oncogene in leukemogenesis, IL‐3 dependent murine hematopoietic cell line, FDC‐P2, was transfected with the plasmid containing cDNA of P210 bcr/abl oncogene (pGD'210) or murine IL‐3 (pcDmIL3) by electroporation. Four out of five pGD'210 transfected clones as well as FDC‐P2 transfected with pcDmIL3, acquired autonomous proliferation (i.e. lost the requirement for IL‐3 supplementation). The expression of bcr/abl oncogene was weak in one clone, which remained dependent on IL‐3. Unlike pcDmIL3 transfectants, which secrete IL‐3 into the supernatant, IL‐3 was not demonstrated in the culture supernatant of pGD'210 transfected FDC‐P2. These findings suggest that P210 bcr/abl oncogene is directly associated with autonomous proliferation, which is the first process of leukemogenesis.
