Certain features of polyamine metabolism and pathogenetic functions in the mononuclear cells of the patients with chronic В-lymphocytic leukemia and acute monoblastic leukemia (М5)
Summary. Aim: a comparative study of the polyamines (PA) metabolic characteristics in the chronic В-lymphocytic leukemia (B-CLL) and acute monoblastic leukemia (M5) (AML(M5)) mononuclear cells, including multiple correlation analysis of the relations between the PA metabolic characteristics between one another an with certain hematologic parameters. Results. The putrescine (Put), spermidine (Spd) and spermine (Spn) content, as well as total arginase activity, was shown to be significantly lower in the AML(M5) than in the B-CLL mononuclear cells. At the same time, Spd/Spn ratio was essentially higher in AML(M5) than in B-CLL. In B-CLL, the sexual difference between the PA metabolic characteristics was absent. In contrary, in AML(M5) the average content of Put, Spd and Spn, as well as total arginase activity, was lower in women than in men. Conclusions. The correlation matrices of the hematologic and PA metabolic parameters for B-CLL and AML(M5) mononuclear cells were quite different, and this shows essential differences in the PA involvement into the B-CLL and AML(M5) pathogenesis.
