英文摘要
Human myeloid leukemia K562 cells be induced to differentiate to mature cells bidirectionary, i.e., hemin induces erythroid differentiation, while 12-O-tetradecanoylphorbol 13-acetate (TPA) induces differentiation to monocytes. TPA is a potent inducer of heme oxygenase (HO), which catabolizes heme to biliverdin. An HO inhibitor, tin protoporphyrin (SnPP), suppresses TPA-induced K562 cell differentiation to monocytes. We show that TPA suppresses hemin-induced erythroid differentiation of K562 cells, while retinoids augment it. Futher, an HO inhibitor, tin protoporphyrin (SnPP), suppresses TPA-induced K562 cell differentiation to monocytes. It was also found that co-treatment of K562 cells with SnPP and TPA induces erythroid differentiation of K562 cells, though SnPP alone or TPA alone does not induce erythroid differentiation, suggesting a role of HO in the directional switch of differentiation.
