Abstract

Objective. To investigate the roles of mouse erythroid differentiation and denucleation factor （MKI）DF)

a novel factor cloned in our laboratory recently

in erylhroid terminal differentiation.Method. Mouse erythroleukemia （MEL） cells were transfected with eukaryotie expression plasinid pcl)-NA-MEDDF. Then we investigated the changes on characteristics of cell growth by analyzing cells growth rate

mitotie index and colony-forming rate in semi-solid medium. The expressions of c-mye and p-globin genes were analysed by semi-quantitative RT-PCR.Results. MEL cells transfected with pcDNA-MEDDF showed significant lower growth rate

mitolic index

and colony-forming rate in semi-solid medium （ P<0. 01）. The percentage of benzidine-positive cells was 32. 8%after transfection. The expression of β-globin in cells trarisfected with pcDNA-MEDDF was 3. 43 times higherthan that of control （MEL transfected with blank vector

pcDNA3. 1）

and the expression of c-rnyc decreased by66. 3% .Conclusions. MEDDF can induce differentiation of MEL cell and suppress its malignancy.
