    Abstract:
    Cyclic cytidine 3':5'-monophosphate (cyclic CMP), cyclic guanosine 3':5'-monophosphate (cyclic GMP), and cyclic adenosine 3':5'-monophosphate (cyclic AMP) contents of leukocytes and urines of leukemic patients have been investigated. We have studied four types of leukemia: acute myeloblastic leukemia; chronic myelocytic leukemia; acute lymphoblastic leukemia; and chronic lymphocytic leukemia. As controls, the cyclic nucleotide content of leukocytes and urines of healthy volunteers and patients with solid tumors selected for their normal hemogram has been determined. It has also been measured in phytohemagglutinin-stimulated lymphocytes. Our data show that: (a) the concentration of cyclic CMP is always lower than that of cyclic GMP or cyclic AMP; (b) in urines, the concentrations of the three nucleotides are higher in patients than in healthy volunteers, the greatest differences being observed between the cyclic CMP concentrations of acute leukemia patients and controls; and (c) in white blood cells, cyclic AMP concentration is lower in leukemic than in normal cells. The cyclic GMP concentration is the same everywhere except in monoblastic cells and leukocytes from solid tumor patients. High cyclic CMP levels are associated only with acute leukemia, whether myeloblastic, monoblastic, or lymphoblastic, a fact which suggests that cyclic CMP could be a biochemical marker of hematopoietic stem cell malignancy.
