全反式维甲酸诱导HL-60细胞向粒细胞分化后，磷脂酰肌醇3-激酶（PI 3-K）活性增加。通过共聚焦显微镜的免疫化学和免疫细胞化学分析也揭示了酶的量的增加，这在细胞核水平上特别明显。抑制PI 3-K活性的纳摩尔浓度的渥曼青霉素和其表达的转染与p85 α的反义片段阻止了分化过程。所得数据表明PI 3-K活性在促进粒细胞分化中发挥着重要作用。
Phosphoinositide 3-kinase (PI 3-K) activity increases in HL-60 cells that are induced to granulocytic differentiation by all-trans-retinoic acid. Immunochemical and immunocytochemical analyses by confocal microscopy also reveal an increase in the amount of the enzyme, which is particularly evident at the nuclear level. Inhibition of PI 3-K activity by nanomolar concentrations of wortmannin and of its expression by transfection with an antisense fragment of p85alpha prevented the differentiative process. The data obtained indicate that PI 3-K activity plays an essential role in promoting granulocytic differentiation.
