We studied fatty acid changes that are likely to occur during phorbolmyristate acetate (PMA)-induced differentiation of HL-60 cells. It was observed that PMA-induced differentiation is associated with increased uptake, but not synthesis, of fatty acids. Fatty acid analysis revealed that arachidonic acid (AA), 20:5 n-3 and 22:6 n-3 levels are reduced with a concomitant increase in 22:5 n-6 in the phospholipid fraction. In the FFA fraction there are increases in free AA, free 20:5 n-3, 22:5 n-3 and 22:6 n-3, and a fall in free 22:5 n-6 in PMA-treated cells. PMA-induced differentiation and nitroblue tetrazolium reduction by PMA-treated cells was only partially inhibited (about 20-30%) by indomethacin and nordihydroguiaretic acid (cyclooxygenase and lipoxygenase inhibitors respectively), but not by superoxide dismutase, catalase or mannitol. These results indicate that PMA-induced differentiation of HL-60 cells is accompanied by specific changes in the fatty acid composition of the cells.
