title: 12-0-Tetradecanoylphorbol 13-acetate (TPA)-induced enzymatic change of human non-T, non-B lymphoid leukemia cell lines.
abstract: Culture of two lymphoid leukemia cell lines with 5 x 10(-9) to 10(-7) M 12-0-tetradecanoyl-phorbol 13-acetate (TPA) induced the significant increase in sialyltransferase, acid phosphatase and butyrate esterase activities, the decrease in poly(A) polymerase and terminal deoxynucleotidyl transferase (TdT) activities. B4-, J5-, TdT- or PNA-positive cells were decreased in TPA-treated cells, while B1-positive cells were increased. These results suggest enzymatic changes as an aspect of TPA-induced differentiation in lymphoid leukemia cell lines. These enzymatic activities may be useful markers for the differentiation of lymphoid leukemia cells.
