In some instances of acute myelogenous leukemia (AML), erythrocytes or platelets also expressed the glucose-6-phosphate dehydrogenase (G-6-PD) isoenzymes which were detected in the leukemic cells.
Therefore, we tested whether these leukemias could be distinguished with respect to their involvement of immature precursors by studying colony-forming cells (CFC) and their precursors from four glucose-6-phosphate dehydrogenase (G6PD) heterozygous patients with AML and five patients with CML.
In the present study, LTMCs were established from two patients with newly diagnosed acute myeloid leukemia (AML) who were heterozygous for the X-linked enzyme glucose-6-phosphate dehydrogenase (G6PD).
The five glucose-6-phosphate dehydrogenase (G6PD) heterozygous patients with AML studied manifested only a single G6PD type in blast cells and in most or all granulocyte colony-forming cells, indicating that the leukemias developed clonally.
To determine whether acute nonlymphocytic leukemia develops clonally, to study the pattern of differentiation of the involved stem cells, and to determine whether clinical remissions are true remissions, we studied 27 patients with acute nonlymphocytic leukemia who were heterozygous for the X-chromosome-linked glucose-6-phosphate dehydrogenase.
In order to study the pattern of B cell involvement in acute nonlymphocytic leukemia (ANLL), multiple B lymphoid cell lines were established by Epstein-Barr virus transformation of peripheral blood mononuclear cells from two patients with the disease who were heterozygous for the X chromosome-linked glucose-6-phosphate dehydrogenase (G6PD).
Four patients with acute nonlymphocytic leukemia who were heterozygous for the X-chromosome-linked enzyme glucose-6-phosphate dehydrogenase (G6PD) were studied to determine the numbers and types of progenitor cells in which the disease arose.
Two patients with acute nonlymphocytic leukemia who were heterozygous for the X-chromosome-linked enzyme glucose-6-phosphate dehydrogenase were studied to determine the number and type of cells in which the disease arises.
