Abstract

Leukocyte alkaline phosphatase (LAP) is synergistically induced by the combination of all-trans retinoic acid (ATRA) and granulocyte-colony-stimulating factor (G-CSF) in acute promyelocytic leukemia (APL) cells (Gianni′ M. et al., Blood 83: 1909-1921, 1994). The role of cAMP and tyrosine kinases in the induction of LAP was investigated. In the APL cell line NB4, adenosine-3′: 5′-monophosphothioate, cyclic, Rp isomer, a reversible inhibitor of cAMP-dependent protein kinase (PKA), has no effect on the induction of LAP enzymatic activity and mRNA triggered by ATRA + G-CSF, in conditions where this compound completely blocks the upregulation of LAP transcript caused by the combination of the PKA agonist, dibutyryl-cAMP (db-cAMP), and ATRA. Challenge of NB4 cells with G-CSF, dbcAMP and ATRA causes a much higher induction of LAP relative to that observed in the presence of ATRA + G-CSF or ATRA + dbcAMP. Treatment of NB4 with ATRA and G-CSF results in increases in tile tyrosine phosphorylation of several proteins. In the presence of the cytokine and the retinoid, tyrosine kinase inhibitors decrease LAP enzymatic activity and mRNA.
