To further investigate whether cyclin A played as a key molecular in cell proliferation, HL-60 cells were exposed to different concentrations of hexamethylene bisacetamide.

为了进一步研究cyclin A在白血病细胞增殖中的作用，用在体内、体外均有抗肿瘤作用的六亚甲基二乙酰胺在体外抑制白血病细胞系HL-60增殖，并诱导其分化。

To further investigate their roles in cell proliferation apoptosis and differentiation, three human leukemia cell lines (K562, U937 and HL60) exposed to various concentration of hexamethylene bisacetamide, a potent inducer of differentiation of transformed cells both in vivo and in vitro, were used as an in vitro model for the study of cell proliferation, differentiation and apoptosis.
