Abstract
Both S-100 antigen and calmodulin were shown in normal lymphocytes with S-100 being decreased in lymphocytic leukemia cells. Although small amounts of S-100 antigen and calmodulin were shown in acute myeloblastic leukemia cells, they could not be detected in normal granulocytes. In lymphoblastic leukemia, S-100 antigen levels in T-cell leukemia cells were higher than in B-cell leukemia cells, while calmodulin was decreased in chronic leukemia cells. In mitogen-stimulated lymphocytes, the levels of S-100 antigen were decreased, while those of calmodulin were either increased or unchanged. Calcium-dependent cyclic nucleotide phosphodiesterase was highest in acute lymphoblastic leukemia. These data suggest, therefore, that calcium ions may play a role in the proliferation, differentiation or leukemic change in lymphocytes and, hence, that measurement of calcium binding proteins may be useful in the investigation of leukemia cells or lymphocytes.
