摘要: Abstract At subtoxic concentrations, aclacinomycin is effective in controlling erythroid differentiation of K562, a human erythroleukemic cell line. To better understand early events implicated this process, we have used bisindolylmaleimide (GF109203X), an inhibitor with high selectivity for protein kinase C (PKC). Our data show that GF109203X inhibits effects on evidenced by strong reduction hemoglobinized cells and marked decrease mRNA rates genes. establish firmly PKC involvement, also verified stimulates its rapid translocation, from the cytosolic to membrane compartment. By Western blot analysis, after short induction times, PKCα was most implicated.
