neoplasm

increased leukemia incidence ( J:140628 )

• following pIpC treatment 14 of 22 mice developed acute leukemia

• median latency for leukemia development was 131 days

• infiltration of the bone marrow, spleen and liver with immature hematopoietic cells is seen in moribund mice

• mice may develop either acute myeloid leukemia or acute lymphoblastic leukemia

• gene expression profiles in mice with acute lymphoblastic leukemia recapitulate gene expression profiles seen in human acute lymphoid leukemia
