The authors measured the human pim-1 protooncogene (PIM) expression during fetal development and in hematopoietic malignancies. The data indicate that during human fetal hematopoiesis the 33-kDa pim product, p33pim, is highly expressed in the liver and the spleen. In contrast, a the adult stage it is only slightly expressed in circulating granulocytes. Out of 70 hematopoietic malignancies analyzed, 51 patients and 19 cell lines, p33pim was overexpressed in {approx} 30% of the samples, particularly in myeloid and lymphoid acute leukemias. This overexpression was unrelated to any stage of cellular differentiation and was not due to gene rearrangement or amplification. These results imply a physiological role of the pim-1 protooncogene during hematopoietic development and a deregulation in various leukemias.
